First question is what is your age? Youth heals faster than those with more years. However, even in the best situation healing takes time and there is no replacement for time. Your doctor has taken your specific situation into account and I am going to bet that your provider knows more than you or I about your procedure, healing time, failure rates for the procedure, failures for those that do not get and follow through with PT. Now, as you are on this site I am going to guess that you are an adrenaline junkie like the rest of us. And that means YOU DO NOT know how to just go out and have a good time and take it easy. Your addiction to adrenaline needs to be found in another way until your provider fully releases you to ski. This allows you to ski another day. Returning to rapidly to skiing and re-injuring yourself could terminate you from skiing for ever. Do not be too anxious to cause planned failure. I have not had the same injury you have but I have had many injuries and had to sit out seasons from many sports. I am also not one to follow all advice from medical providers including my own. You can still drive the boat to be involved and or teach others. But running, bike riding, and the gym may be your wisest choice until next snow skiing season then return to the water in the following summer.

I have had low left side back pain for many years. For the last five years the pain wakes me up in the morning. Then I move to the floor and stretch, acupressure, to function for the day. I spend an average of four days a week at the gym and I am very active for 59 years old. I found this training video here and started it. I have not woken up in pain once since starting this. I am doing this every morning before going to the gym. My wife is even following this workout. Horton thanks for this post and thank you Dr. Goodman.

Thanks Marcus this is a great tutorial. Seeing the difference slowed down and explained really gives one something to aim for. With help from your neighbor Matt and the videos that Abby would take of me at your lake or our home lakes my skiing still sucks. However, I no longer have low back pain after skiing. I attribute that to better body positioning that came from seeing video of myself skiing. I am a visual learner and you also explain in ways I understand.

IWWF Disabled World Championships 2023 7 hours ago Current World Record Holder in Women's seated Trick skiing Abby Dunn is at Elk Grove CA to defend her title by setting a new record. Ya, go Abby. For those of you that don't know or keep up with her. Besides being beautiful, humble, and talented, she is also a sweet heart. Oh! And besides being on the University of Arizona's Women's basketball team she is one of the newest members of the U-25 USA Women's Disable Olympic team and will be competing in Thailand. Wish Abby luck when you see her.

About 10 years ago I had an acoustic neuroma removal on my left 8 cranial nerve. The process required removing about a 2 inch portion of my skull. Then the piece of skull was put back with some clips. Because of my age I was told the bone would probably never grow back strong. Then there was 3+ years of hell so I did not want to have any further TBIs. So I also did the search for a helmet also. I looked at bike helmets, snow skiing helmets, and hockey helmets. I needed something that had coverage behind my ears and down to the bottom of my ears like a open face motor cycle helmet. My first thought was a ice hockey helmet. While looking for helmets I found a Bell skateboarding helmet and I have been using it ever since. It is typical strya-foam inside about 1/2 inch thick with very thin padding in the head area and thicker padding in the cheeks and hard outer shell, much thicker than a bike helmet and similar to my Briko down hill race style helmet (not your regular snow skiing helmet seen on most people on the hill) although not as well designed internally. The Briko may be a better option they are FIA approved race helmets and comfortable. The Bell skate boarding helmet has done well with the water as it has very little padding so mold and drying has not been an issue. It is also not extremely comfortable as my Briko or my Aria are, but I don't have it on for long periods like I would motor cycling ridding or snow skiing. As Slalom.Steve has stated the helmets could cause a bigger problem and I agree. I could see the edges catching and snapping ones neck. But I am still here to say this has not happened yet. I have stacked it pretty hard a few times with the helmet to the point the driver and spotter thought they were going to have to pull me out of the water and call a helicopter. Because of the helmet I just readjusted it and said hit it.

I will add my $0.02 to this topic. I prefer pressure treated wood and in the west that is usually Douglas Fir. Douglas Fir is structurally much stronger than pine, and fir and especially Ceder. Cedar although will withstand weather better, Cedar is not used structurally. I would not use Cedar to support your boat. Bunk carpet comes in sizes to wrap three sides of the boards. This is to allow air to have access to dry out the boards and carpet. Wrapping the entire board does look better but will hold moisture causing mold and premature wood rot. All of your staples should go on the side of the boards not on the surface in contact with your boat. Wrap the ends as you would with wrapping paper on a package and staple in place. The carpet should be installed after you have fitted the lumbar to the trailer frame. I would use lag bolts and finder washers stainless or galvanized. The bolts must not go through the boards into the surface where the boat will sit. Pre-drill your holes about 1/2 the thickness of the board with a drill bit smaller in diameter than the bolts you choose to use I would guess 1/2 inch diameter bolts. Now here is something that has not been discussed and that is fitting the boards properly to the trailer. This takes a bit of planning to be done at a boat ramp/dock. I have done it and this depends if some or all of your attachment points are welded to the trailer or you have some that are adjustable. The bottom of our ski boats are fairly flat but there is some curvature toward the front. The boards need to curve to fit the bottom of the boat prior to bolting the boards fully in place. Other wise when the boards bend into place some of the bolts will be ripped out of place. I have use a floor jack and spare lumber to aid in this process of proper fitting the boards to the bottom of the boat and mounting location.. Put the boat in the water at a non-busy ramp, dock it, anchor or send the family out for fun. Pull the trailer out and find a spot you can park and work on the trailer. Measure the old bunks and make your new boards the same length or longer as the curving of the boards will change the bolt location when the boards flex. So a little longer is better as you can cut to final length after the boards are in place. Remove the old boards and set the new boards one by one in place, start at the front of the trailer and pre-drill one hole in the boards and place a bolt and washer in place snug it. If you are on the flat portion of the boat bottom you can do this at all of the brackets. When it comes to the curves/angled section towards the front of the boat continue to place one bolt in place and then bolt loosely in the second bracket from the front to help hold the boards in place. Do this with all of the bunks. Place the carpet on the bunks wrapping the front ends of the trailer boards and leaving the rears unwrapped until the boards are bent into the proper shape for proper length. Then put he boat on the trailer gently making sure the boards stay in place as you slowly pull the boat out of the water with friends monitoring this for the driver. Go back to your working area hopefully very close to the ramp, no bumps in the road surface. Now the boards will be conforming to the bottom of your boat. Crawl under the trailer and finish pre-drilling the holes in the bunks and bolting the boards in place. Sometimes a jack and some persuasion is needed to get the board angled properly as you are bolting the boards in place. Finish stapling the carpet in place and wrap the back end of the boards. To some, this process may seem overkill but when you bolt the bunks in place without allowing for the curvature of the bottom of the boat to bend the board properly. The bolts then under the weight of the boat get pulled out of their position and now you have destroyed your surface to mount the bolt to. So this is the process I have used to put new bunks under a boat. I have one boat I did this to with 20 years ago and one from the factory that is 23 years old and they are both in great shape today. Side note: West Marine has many tutorials on their web page on do it your self boat projects with reason why you do certain things a certain way such as bunks and anchoring.

I have a friend that trains a Queens Creek AZ. It is a beautiful location and looks close to Phoenix. I have no idea if there is any access to the public or anything else about the property. I have just seen pictures of Abby skiing there.

Agree, build up to a heavy weight for yourself and dead lifts and continue to hold the bar at the end of your set until the bar is dropping put of your hands. Same with shoulder shrugs. Over all strength is important leg and core. If your knees allow you to do squats do them finishing each squat squeezing your glut together straightening your low back. And, yes the slow acceleration for the driver allowing you to regain that feeling of equal forces being applied to your feet and legs while playing a balancing game with the grip you have.

I was hoping to be there but did not make it. My son Jacob and Abby have gone to school together since kindergarten. My first experience with adaptive skiing was Abby's second year getting to ski with Ability First. Jacob and I were heading home from a California state championship school sports event and Abby texted Jacob and said I am at this location skiing, you should stop by, and we did. The coaches and boat driver asked if we were going to ski with Abby and we said yes. Then jump in the boat and learn how we work with the adaptive skiers. Although Abby had a schedule to keep and needed to leave. My son and I stayed and worked with the coaches and athletes. The coaches looked at photos of my son and I skiing and told and instructed us how to fix it. My back no longer hurts after skiing. Winning the state competition was not the highlight of that weekend. Seeing Abby and the other athletes ski is what sticks in our minds of that weekend. I went home and told My wife I really feel like I belong working with this group and we have been invited back to work with and learn from this amazing group since. That was 3-4 years ago and we have been skiing with Abby ever since. We had a group of veterans skiing a few months ago. One guy was 93 years young. He said it had been a few years since he last skied. It turned out a few years was 30 years ago. We eventually got him up on a sit ski. That mans and some of his peers determination and grit showed us why his generation is titled the Greatest Generation.

Awesome! Love to see this, a passion for life. Stay active as long as possible.

Enjoyed watching.

Forgot to add this: https://www.motortrend.com/how-to/1502-sae-j2807-tow-tests-the-standard/

Fastguy888 is on target and many truck manufactures did as he states. However, a new standard came out around 2011-12 SAE J2807 to measure vehicles towing and payload equally. It was something like 2015 that all manufactures were required to fallow the standard. New vehicles all fallow SAE J2807 now. As was stated it is all a legal issue.

Lot's of snow that will slowly melt and hopefully fill up our local lakes, so next season will be amazing.

I have done what BraceMaker suggest although I used a 1x4 and rope. The 1x4 gives a little more area for weight distribution. The draw back of the 1x4 is it wants to float and can be awkward to get a foot on.

Nobody really drives a Fiat. People own them, go for one or two short outings and then has an experience that causes them to become familiar with a tow truck driver. Then a mechanic, and if you choose to keep making payments to these two professions, these people will become like family that you can not get rid of. Oh! wait, doesn't Fiat own Dodge, Chrysler, Jeep, Ram?

That is great. As one who despises political correctness (telling lies to protect others feelings) Someone had to work pretty hard to put into words that level of truth.

I learned on a TapperFlex similar but older then the one in this photo. Then I was able to purchase this TaperFlex 3, Wide Tunnel-66 soon after getting up on a single about 1979-80. I skied that ski and carried it all around the West during different jobs hopping to bum a ski for many years. The Maja I found a few years ago, and to answer someones question about the small yellow washer, it is to keep the front boot from sliding too far forward and falling off. The Cut & Jump Classic is another ski picked up that I planned to make something out of. It is of little to no value so it found a home at the entrance sign to my home. As for my HO VTX & CDX they are not vintage enough to show and are still what I ski on.

The ski, handle, and driver have been talked about and some touched on another issue but did not elaborate, strength. After I have spent the last 15 years as a runner I returned to the gym wit a focus on strength for skiing water and snow. The exercises I like are squats, dead lift, and shoulder shrugs (shoulders to ears). I do the dead lift and shrugs slowly as if I am getting up from a deep water start or making a cut and hold until I am making the next turn (6-8) seconds. These exercises are not only great for the legs and low back but they build hand strength also. These exercise have made it much easier for me to get out of the water even at 57 years old and multiple tendon transfers in my left arm. Then add cardio so you can hold your breath long enough so the spray is no longer in your face and you can take a breath. Putting together all of the above mentioned information from the other Ballers plus specific strength exercises and weight loss you will be successful.

Looks like fun but I will stick to my season pass and hopefully powder.

When listed as West I assume it is in the Western United States. Were is Lake 38? When I google it the only Lake 38 I get is in Florida. Florida is west of Europe.

It has a torque converter. The clutches are located inside the torque converter just like on a car with an automatic transmission. The ZF 63 A is a gear reduction trans instead of a 1:1 ratio as in many boats. In gear forward and in gear reverse is it, the torque converter is doing the work. ZF 63 A Description: Reverse reduction marine transmission with hydraulically actuated multi-disc clutches. As discussed in the article I listed above the friction modifiers can be beneficial if you are experiencing torque converter shudder. For about $8.00 you can see if that works. I would start with two ounces. If that helped but did not resolve the issue completely I would add the other two ounces and see how that works. If that does not work then you may be looking at another issue. ZF 63 TECHNICAL DATA SHEET Torsional Vibration and Torsional Couplings The responsibility for ensuring torsional vibration compatibility rests with the overall propulsion system integration responsible party. Compatibility check of torsional vibration must include excitations induced by engine governor. ZF cannot accept any liability for gearbox noise or for damage to the gearbox, the flexible coupling or to other parts of the drive unit caused by torsional vibrations. Contact ZF for further information and assistance. For single engine powered boats, where loss of propulsion can result in loss of control, ZF recommends the use of a torsional limit stop. It is the buyer's responsibility to specify this option. ZF cannot accept any liability for personal injury, loss of life or damage or loss of property due to the failure of the buyer to specify a torsional limit stop. ZF selects torsional couplings on the basis of nominal input torque at commonly rated engine speeds. Consult ZF for details concerning speed limits of standard offered torsional couplings, which can be below transmission limits. Special torsional couplings may be required for Survey Society requirements. So if the friction modifier does not work. Based on the above technical data sheet I would surely check shaft alignment and prop that could cause torsional vibration. But based on your description, that as trans warms up it gets worse I doubt alignment is causing vibration. If the friction modifier solves your problem great. If not it eliminated one option. The other option is to replace the trans. The trans are about $3000 not installed and with winter coming on I would want to know if I needed to replace a trans over the winter so you are without a boat next year. Just my $0.02

I would consider adding a friction modifier 2-4 oz. To see if that quiets it down. They are made by many companies such as Red Line, Torco, AC Delco, Yukon Gear. Below is a post from "Bob's The Oil Guy" https://bobistheoilguy.com/forums/threads/what-do-friction-modifiers-do.37756/ site and it is a good description of what is occurring. It is cited at the bottom. I have used the Red Line product in a limited slip rear differential and it quieted it down instantly. I have also used it in a new transmission that had a small amount of torque converter shudder and the shudder stopped in a few miles. "Perhaps I can lend some insight to the topic? Before you can understand how friction modifiers function, it is important to understand how "wet" clutches perform. In a wet clutch arrangement, there are three stages of engagement. During the first stage, the clutch is not in contact with the pressure plate or other metal plate. We will use an automatic transmission torque converter as an example. Anyone who has driven auto trans cars with lockup torque converters for a while has probably experienced a phenomenon known as "lockup shudder" or "torque converter shudder". Shudder is caused during torque converter clutch lockup by burnt fluid or fluid wich has exhausted all of it's friction modifers. The result is a chattering feeling when the torque converter goes into lockup mode. I will now attempt to explain the physics of wet clutch engagement. As I have already mentioned, during the first stage the clutch is not in contact with it's mating surface. The fluid itself, however, is acting as a viscous coupling, causing a partial engagement. A side effect of this is heat, and I believe you all know that heat is the killer of automotive oils. The second stage is very simlar to the first. At this point the clutch is very close, possible within thousandths of an inch, from it's mating surface. The viscous coupling is now more effective, but the pressure and shear load on the fluid are also higher, and the result is increased heat. During the third stage, the clutch actually contacts it's mating surface and positive engagement is reached. The shear load of the fluid has been overcome and has either extruded itself outside of the clutch material or, depending on the application, has partly or entirely extruded itself through a porous friction material, thus exiting the engagement area of the clutch. Now that we have an understanging of wet clutch engagement, lets see how that plays out in the real world. If a fluid has lost a substantial amount of the friction modifier, the shear of the fluid will be inconsistant accross the engagement surface and the clutch will briefly alternate between full engagement (stage 3) and viscous engagement (stage 2). The as power through the assembly varies, wich is connected in our case to a vehicle that we are inside of, a bucking of sorts is perceptable to it's occupants as power transmitted to the wheels is momentarely interrupted and regained. In an application like a limited slip rear end, similar phenomena occur but in a slightly different manner. Because the clutch plates are constantly loaded with heavy springs, in theory they should always remain in stage 3 of lockup. If that were the case however, they would never slip. So the purpose of a friction modifier in a rear end is to ensure that the transition from S3 to S2 and back again during cornering etc. is smoothe. Therefor chatter occurs in much the same way it does in our torque converter clutch scenerio. So the answer to your question if friction modifiers enhance friction or reduce it? The answer is there is no answer. Depending on what the application calls for and how it is engineered, they can do either. So as Alex said, it does just that; modifies friction. And now hopefully you will understand why and how as well". [smile] Pete [ January 06, 2003, 10:09 PM: Message edited by: Pete2k_Z28 ] Hope this information helps.

If the work you did on the loose wires you discuss does not resolve your issue, I would be looking for a short in the system. A wire that has the insulation worn off touching metal. It could be anywhere, but there is not a lot of metal so I would concentrate around the circuit breakers and motor. Gremlins like that can be so simple but are a nightmare to locate. Look at each wire from one end to another. It can be time consuming.

D. Is my expensive ski visible for all to see especially those who may desire to own it more than you desire to keep it. Just something to think about.
