Older inboard wake/ski performance

Ice is out, and the last two days I skied an '87 MC 190 open water at 28 off, and barefooted behind it tonight. I also pulled a very recreational skier at 15 off 30 mph who raved about the tiny wake. Until 2010 this boat was our primary tug with PP and I know all about the short-line spray...but she tracks nice and the wake is really great. In '07 I ran 35 off at 36 behind her, and have 38's at 34 behind her as well.

 

Jump up a few years to '91-'94 MC 190 with EFI and spray relief pockets and PP...even better and available on the dirt cheap today.

 

Even better a '97 on up GT-40 SN 196. No more spray issue, better tracking yet, rope never catches on bubble but, fantastic wake.

 

A good number of Ballers need to train ZO and behind the latest boats both for enjoyment and similarity to their tourney conditions. For those who don't there are fantastic options out there at terribly reasonable prices. The last few days shows me there is a lot of on the water fun to be had behind a '87 MC 190...and if I were never going to ski a tourney again I could live with that boat in the buoys (tho may need some spray goggles until I'm too old to go short).

WSM did an article listing best of the best older rides. Like above, the early 90s MC, and bubble back SN were listed. They also listed the 80s Supra ts6m. A shortliners dream boat. No spray, rail like tracking and styling lines and looks a decade ahead of anything and everything of that era.

Yes the late 80's-91' MC were affectionately called 'aqua massages' in shorter line lengths and or in some wind! Next generation of ProStar is really hard to beat. MB 190s and 200plus are very nice too, similar hulls and big trunks for family gear. Centurion Falcon-Eclipse wakes are great for slalom of all ability and speeds.

@RAWSki - We've been using a '97 MB 190 at the public lake for the past three years. With PP speed control and a GT40, it's perfect for what we need there.

 

The 200 at the club is admittedly better in terms of spray as the line gets short.

It really is a shame that so many really good boats are obsolete (at least to many competitive skiers anyway) just because of speed control technology. I'd guess it does quite a lot of damage to the sport.

When it comes time for my new boat, it will likely be a late 90s early 2000s SN 196 or 90s mastercraft and I'll restore it. I've seen more than one top level skier train behind a PP equipped boat then jump behind a zo boat and still run into or through 38 off....While I'm no pro level skier, these actions speak volumes in my mind. I ski behind my 93 malibu euro f3 I restored, a 2003 SN 196 and 2014 prostar zo boat and do the same behind each (-28 with -32 attempts last season at 34) I just want to have fun though :) I'm sure there is a difference but it doesn't stand out as "slap in the face" to me

@9400, I use a '97 Nautique that I repowered for ZO with an Excalibur 343. Over 800 hrs on the new motor in 3 seasons. Runs like a top and from the skier's standpoint, no difference with the newer boats. Total of 2500 hrs on the boat.

 

Nothing wrong with the GT-40, but needed ZO for several reasons.

If it was easy, they would call it Wakeboarding

Last season in a tournament behind a 2014 MC with ZO....1.5@39 and I train 85% of the time behind a 97 SN with CLASSIC PP. I mean CLASSIC..it's original to the boat. It's not about finding a match to train behind. It's about finding a ZO setting that makes if feel easier then what you train behind.

@wish like you I train PP classic but perhaps 98% percent.

 

Both of us would be better at tourney's if we trained ZO.

 

If a '91-'94 MC Prostar with LT1 could have ZO...anyone could train better for tourneys for a very low price of entry. Similar argument for a '97 onward SN 196. Reasonable price of entry.

 

Running this carb, 240 hp, '87 MC for the last week with PP free skiing at 28 off has certainly brought to the forefront the fun factor of simply having a boat and skiing. Traffic is stopping to watch us, kids with jacked up pick-ups at the park are intrigued by the V8 sound (and the sound of Led Zeppelin from the stereo as we change over). Wake kicks butt...I'm having a riot.

@6balls I got my GT40 2000 SN pretty damn close to ZO feel and times with Z-box and some tinkering last fall. After the club boat sold early, my old tug stood in for a month and it felt great. In one instance we were training behind it on Friday, tournament on Saturday with actual ZO and we were fine. If anything actual ZO was slightly easier feeling. You can hear the old Ford reacting and settling down nicely, ignore the skier lack of skill.

Been back and forth between a LXi ZO and mine for 3 weeks now. No performance differance in how I ski. There is a difference in how they feel but it seems easier behind ZO. And my GT-40 runs 10x smoother then the LXi soooo...tough to drop $$$ on a paid for boat. Did several months on a 200 a while back and also noticed very little improvement in my skiing and didint really mind going back to PP. Will convert in a few yrs when my clock hours reach closer to 2000.

@wish I think as long as you are getting in some regular ZO time and have settings etc...it's ok to go back and forth. More difficult when there is only PP all the time, and then a tourney here and there.

I like this thread a lot. But it has me thinking about the wake on my older boat...

 

As I mentioned above, we use a 1997 MB Sports Boss 190 at the public lake. As I understand it, that boat is built using the '91-'94 Prostar hull. And that's when it got me thinking, I wonder what tweaks can be done to improve the wake?

 

The boat skis well for sure... But what adjustments might make it ski even better? Weighting the front? Anything else?

 

We don't use that boat in the course at all and already try to keep it as light as possible by not carrying extra stuff.

@pgmoore I don't see much reason to improve the wake on a '91-'94 MC...or even the '87 MC I'm free skiing at the moment for fun. Great wakes...lack of current horsepower/speed controls and spray at shortline. Aside from that...great ski boats.

@6balls - fair enough. Totally plausible that there is nothing worth doing. Which is great! That makes me happy for sure!

 

In terms of horsepower, to be honest the GT40 has been just fine for our needs. We only slalom (no barefoot) and I've yet to find a person that I can't pop up out of the water.

 

And as for speed control, I will concede that my Stargazer system is not the same (or as good) as the ZO in the club boat. But would recommend it to anyone over nothing. It's a marriage saver for sure!!!

@9400…I have a repowered TSC1 w/Zero Off. Thanks @Jody_Seal I think it's basically the best thing going. It's almost as good to ski behind as a $40-60K boat. I'm a fairly active tournament skier and routinely drive/ski the newer boats. I don't find it hard at all to go from my boat to one of the newer models of any manufacturer. The wakes/spray are marginally better, but the zero off pull difference is not really an issue. I originally wasn't planning to get a Zero boat, but I can't imagine not having it now.

If I lived closer to @Jody_Seal , my bubble butt would be ZO converted. Skied it open water today at 28 off as we still have no courses in the water. Have to give slight edge 28 off wake 34 mph to the '87 MC. Tracking, power, drive-ability, to the bubble butt. Obviously as line gets shorter the spray issue would come up...otherwise again favorable performance by the old '87 MC.

My 97 SN Bubble butt has the Jody Seal (ZO and new engine) treatment and is fantastic to ski. We also have an 07 SN (ZO)196 and switch back and forth daily. The 97 has the step on the gunwale lined with rubber making it the easiest boat to get in and out. I would do it again in a heartbeat! If I was getting a new boat, I'd probably trade the 07 out.

@liquid d I like no trunk as well. Easier to the platform. The newer TSC's I think drive a little more like a train...has a heavier feel and flatter attitude.

The bubble butt goes in the water today at the swamp...next task will then be raising two courses and we're off to the races.

@6Balls, you do have a nice boat already in the MB and the wake is very close to the current boats, you might try a little weight in the bow or perhaps a different prop but that's about it. If you aren't using it in the course then it's probably just fine "as is" Just Ski It!

@rawski the '87 MC 190 is my buddy's boat...you are right in that outside the course it's a great ski boat. For anyone up through 28-32 off it's also great just get the spray going any shorter.

 

We just dropped in the dock, boat lift, and boat at our ski swamp with 2 courses along with my 196. No need to set it up any better...all dialed in! (just lacks ZO but oh well).

 

There's a guy nearby selling a '93 MC 190 with 386 hours and the 285 hp Indmar for asking $9K. Will make a fantastic boat for someone and a TON of boat for the money.
