Baller ReallyGottaSki Posted March 21 Baller Share Posted March 21 Welp, my next boat project has commenced, and seems time to begin a photolog/discussion. I can only hope a photolog remains for posterity, However it appears my 351 build in ccfan lost its images, as well as my RCB build here lost its images, but alas! Lets play boats! My 82 Supreme went offline two summers ago, just as my RCB project boat came online; its pylon was getting creaky and its old bones were just too soft. Why bother one asks? because this boat consistently provided the best ski experience i've ever had. And not just for me but for the family and others. I embrace the challenge of improvement, making a mind-melting, unique old ski boat, making people wonder why such a thing is not available in 2024, I contend the 26-30 mph skiers got shortchanged in the incremental pursuit for record shortline performance. Then we ask where are all the new competitive skiers? 3000#+ boats cannot perform well in this realm, no matter the cost. Weight, with new draggy hulls create more propwash volume, that hump becomes the new 'wake' no matter how wide they make the boat. aim it make it no heavier than before, add some spray rails, no wood. Coosa/1708/epoxy layups. Play with carbon engine cover and platform just cuz. Beware this is going to take a while, going to look worse before it looks better. we will learn new skills along the way. Will be much slower than the prior projects, i welcome your patience , interest and dialogs 5 Link to comment Share on other sites More sharing options...

Baller eleeski Posted March 21 Baller Share Posted March 21 Big project! Absolutely worthy. Enjoy the build. Are you going to add ZO? Some things did improve with time. Old boats with ZO are magic. Do you have a link to the RCB build? Eric 1 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted March 21 Author Baller Share Posted March 21 Thank you both, @eleeski I don't see using zo on this, but will get pp w/zbox. The engine is enhanced, snappy responsive with strong midrange , the boat is light, i hear this is a combination that works well together with that system. here is the link to that RCB build. I had just started rebuilding the images after the site migration, but then suddenly the thread was no longer editable, i regret not acting quicker.

Baller Fine409 Posted March 21 Baller Share Posted March 21 @ReallyGottaSki Interested to see how you build your carbon fiber platform - post up the details there when you tackle that piece! 1 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted March 22 Author Baller Share Posted March 22 Deck came off last spring, but then the hull sat outside for rest of the year. Here it was brought inside and the floors were zipped off. An oscillating tool is the best low-dust, fast solution for demo, just chase the blade with the shop vac as one goes. Stringers removed similarly All fittings removed, Grindy grind grind 6 Link to comment Share on other sites More sharing options...
Baller DvarianDan Johnson Posted March 22 Baller Share Posted March 22 @ReallyGottaSki Outstanding work. Huge job. Not for the faint of heart, but you're doing it absolutely 100% correct. This will be an amazing boat when completed. I love doing the rehab/restore route so much more than buying something new. Keep the pics coming. Hopefully these wont get lost. 1 Link to comment Share on other sites More sharing options...
Baller Dano Posted March 22 Baller Share Posted March 22 @ReallyGottaSki are you using coosa for the stringers too? Do you have to then laminate a bunch of pieces together to get the required thickness? Will Coosa accept lag bolts for motor mounts are do you have to come up with a new design for motor and trans mounts? 1 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted March 25 Author Baller Share Posted March 25 @DvarianDan Johnson thank you, i can appreciate your enthusiasm! @Dano Yes, Coosa for stringers, laminated 3/4 bluewater 26. I will do 2 ply everywhere with a third ply for 6' long from behind trans to ahead of the pylon No, coosa does not accept lags or hold screws well like wood does. i don't have a complete solution for the vertical lags yet, but will now also utilize the holes that transverse the stringers for through-bolt fasteners, these mount fasteners were often omitted I considered an aluminum cradle for a time but have not dismissed it entirely yet here is my drawings and cut plan for the stringer coosa. one note is it suggests one can fab stringers for a 19' ss/mc/centurian or similar from a single sheet of 3/4. An sn could need wider cuts than a single sheet can provide my third ply necessitates getting into a second sheet of 3/4 Transom, plywood removed and ground down Bottom section, first traced onto paper with a sharpie, cut the 1/2 coosa with jig saw and routered a 3/8 radius bevel here wetted with 2:1 , then thickened epoxy sandwiched and clamped with throughbolts and fender washers, wood blocks Upper section of 1/2" bonded similarly, then filleted the next day. the 1/2 bluewater 26 conforms to the transom arc well with a little clamp pressure. next day, 1708 cut and bonded. For a good layup the 1708 is so dense it first needs the substrate wetted, then its chopstrand side wetted, then of course its topside wetted. polyester would sink though the fibers fast but epoxy not so and would result in a dry layup. the transom firmed right up solid after this The doubling at strategic locations did not need precision cuts, and the rudder reinforcement was duplicated. similarly bonded with thickened epoxy, filleted, and glassed in one evening. 2 Link to comment Share on other sites More sharing options...
Baller DvarianDan Johnson Posted March 25 Baller Share Posted March 25 5 hours ago, ReallyGottaSki said: I considered an aluminum cradle for a time but have not dismissed it entirely yet @ReallyGottaSki - I would definitely encourage the aluminum cradle. My 92 has the aluminum frame (box) that sits inside the stringers (and bolt through) with the four pedestals then for the mounts. Maybe this was a more common approach for older boats that I'm aware of - but I haven't seen it in others. Will send you some pics as I'm doing spring maintenance and clean up on it now anyway 1 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted March 28 Author Baller Share Posted March 28 Pylon bracket was heavy steel, and pylon was seized into its lower cup. We had this aluminum bracket and ss lower cup fabbed locally First bonding of 8 footers in the stringer lamination 3 Link to comment Share on other sites More sharing options...

Baller ETskier Posted March 30 Baller Share Posted March 30 Good to see you bring this one back to life. I had Ski Supreme promos in the 80s. My 83 and 84 were great boats. Sharp looking, beautifully appointed, drove well. Best wakes in the business at that time, low, soft, no rooster tail. Downside, tiny trick wake, ha ha.

Just now getting time for Spring maintenance and clean up. Attached are a few pics of the metal box in my 92 Hydrodyne. 1/4 inch thick stainless steel 3 sided box that sits inside the stringers, is bolted through the stringers, and with four square pads for the motor mounts. The pylon as shown has its own 3 sided box as part of this frame. The pylon has a bolt the runs up into the pylon from underneath as well as the U bolt shown. Entire structure is extremely strong. Re-doing an old boat I would definitely go this route. Your project is amazing! 2 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted April 2 Author Baller Share Posted April 2 Raw stringer has been laminated. Placed into boat because we just had to see them in the boat. Precisely sized spacers will keep them true, parallel and square while they are positioned, scribed and shaped. 2 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted April 4 Author Baller Share Posted April 4 Adjusted trailer so the Borrowed laser level can set a consistent floor height based on best fig'rin.this step critical to get the stacked heights correct for the top of stringers to be right after scribing them to the hull so the deck and inner gunnel will all line up again. 2 Link to comment Share on other sites More sharing options...

Baller DvarianDan Johnson Posted April 5 Baller Share Posted April 5 @ReallyGottaSkiOutstanding work. LOVE to see older boats that come back being 10X better than when they left the factory. PLUS - IMO older boats have SO much more style than anything new. Not even close. Keep the pics coming. 1 Link to comment Share on other sites More sharing options...
Baller DvarianDan Johnson Posted April 5 Baller Share Posted April 5 @ReallyGottaSki curious if you're experiencing heavy blushing with your epoxy resin. I know I did with the resin I used but have heard of others that don't blush nearly as much. I'm guessing you've used several over the years? Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted April 6 Author Baller Share Posted April 6 @DvarianDan Johnson no blushing problems yet. On the response we used totalboat without issues, on its floor. Then i got system 3 supplies for the supreme. We ended up first using that system 3 on the outboard Sanger barefoot, floor encapsulation, and coosa bulkheads. All from my regional fiberglass supplier. Lately we did the stern of the supreme, using up the remainder of the totalboat. Remainder of the supreme will be system 3 Im happy with it, because its basically odor free compared to the totalboat. I think my face looked flushed last time i finished up the totalboat. System 3 no reaction Link to comment Share on other sites More sharing options...

Baller DvarianDan Johnson Posted April 11 Baller Share Posted April 11 OK you have to give us some insight into this engine......... 3 Link to comment Share on other sites More sharing options...
Baller ReallyGottaSki Posted April 12 Author Baller Share Posted April 12 I could a bit Dan, Its quite the engine. five years ago it was a 38 yo tired 351 about to drop a valve. I didn't have the means to overbore and pistons for a fresh seal, but compression was still good. I gave the lower fresh bearings, seals, timing chain, oil pump. Camshaft clevite 214/224 112 lsa modest .480 lift. upper is twisted wedge 170 as -cast runners , with machined combustion chambers at 58cc. with the stock pistons CR is now 9.3 lifters from lunati, scorpion std 1.6 rockers, and i measured for the right pushrods Intake is Edel performer, due to height couldn't go bigger. but i port matched to the heads. Front cover is now aluminum, so running a johnson crank pump (can i say that?) vs the sherwood. found some ss commander manifolds from the eighties. all told 141# off the engine lets just say it gives 'spirited' performance its weight to HP exceeds a new prostar with the 6.2, by a whole integer digest these times and distances, and extrapolate what time and distance to 36 may be. it does all this on 87 gas, and uses less of it than all the boats we ski. And the colors came out a bit, steampunk Boat will do 49.5 with three aboard. its done 52.5, but i think it was getting air on one side. it could use bigger carburation so it likely has more in it. I would build similar in a moment. some day it will get the right pistons and zero-decked, but till then, 5 Link to comment Share on other sites More sharing options...
