    Default Project Mini Update: lol, wtf!

    So i decide i'm going to remove the bump rail since i'm going to gel/paint this thing sooner or later. I start drilling out the rivits and i start to notice somthing... Can anybody tell what it is?






    Look it's like a bug, i got a trunk... in the front!




    Well it turns out the f'ing top of the boat was held on by rivits and they used double sided foam take to keep the water out... Actually this is a good thing becuase the top came right off and it's going to make it a hell of alot easier to work on. The hull is pretty thin, i'm pretty sure i'm going to lay some glass to thicken it up a bit. The side of the boat i can flex/move in and out, it's pretty flimsy. ALso this will make it alot easier for me to replace the wood, and to lay full stringers. Oh and sorry guys but my plans changed alittle.... I'm thinking this boats going to become a v-drive... I just dont have the room for the motor and pump.


    I started cuttin out the bulk heads.. First ones out.






    I got a couple guys over on the v-drive section who have some older v-drive units that they are selling pretty cheap. None have shown me any pics yet though

    That's too bad about the v-drive thing. And you had the little pump and everything.

    Is that a baseball bat?

    ya my son through his little bat in the boat apparently. Problems i see with doing a jet....

    1. Room, when i talked about this before i was going to attempt a southwind dragster look, but thats going to require me building a box attaching it, making it strong, etc..

    2. The little pump is cool, but i'm not quiet sure how strong this pump will be, also i'm over powering the pump and that impeller is not designed for the amount of power i'm going to be putting down. I'm affraid it's just going to cavatate instantly.

    3. Pump parts, they dont make that pump anymore, nor do they make replacement parts. Finding impellers, shafts, bearings, etc will be difficult i'm sure and probably expensive.

    4. That little pump pushed a old school jetski to i think 30 mph... thats a bit slow, if i got done with this and the boat only ran 30 while the motor was screamin at 6K that would suck.

    The boat with a v-drive should scoot along pretty good, if i can figure it out/mock it all up. I'm not very fermiliar with v-drive boats. The setup seams simple. I need a strut, a shaft log, and v-drive...

    GREAT! Those '6J' pumps are junk, even with Scat Trax stainless impellers. You will need stringers to mount all the stuff. BUT FIRST!!! You MUST make a solid SQUARE level dolly to do your work on. With the deck off, that hull bottom is "all out of shape". How heavy is the motor you want to use? I've done a few "one off's" in my little 12' 2" deals years ago. PM me and we can go over some stuff, if you like.

    I doubt the deck was doing anything to help keep the shape, what i am concerned with is the bulk heads, i only got the first one out now but when i cut the other one out and remove that one in the back i'm wondering if the boat is going to hold it's shape. THe transom has a 1" thick peice of plywood so that rear aint going anywhere... it's kinda rotted looking too though so i might pull that out too. It looks like a pain in the ass because they did glass good and then glass, but not just a sheet, it's as thick as the rest of the hull.

    As for the square dolly, how would i build this? Do i just need two supports and that run along the strakes?

    You should also have the new bulkheads ready to install prior to removing the existing ones.. The dolly is just so the bottom stays flat (does not twist or sag) while replacing the bulkheads... Shaun.. Cut some 2X4's & screw them from one side of the boat to the other where the bulkheads are before removing them......

    Wow that was a bad way to get level flotaion, more like a bobber in the water. Also that's what is called a shoe box fit. If I were you I would tab the deck to the hull when you get done painting it and put it back together. After that take some silly cone and run it around the perimeter to keep out the water.Then put on the rub rail.

    Actually i was thinking i wanted to try to cap the boat, not sure how easy that would be. The deck fits over the hull so there's overlap.. To cap it i'm guessing i would need to cut off this overlap and then glass the deck and hull together..

    Todd, where you at?

    To cap it is no problem..Sand the inside surfaces where you will be glassing..Position the deck where it fits the bottom good and sits level...Glass the inside & then grind the excess off of the outside and glass the outside..

    "Flat, LEVEL, and good equal support" is what makes a good dolly. YES! The deck is creating some of the hull bottom shape, good or bad, it works that way! The "shoebox' deck to hull attachment is the STRONGEST way to do it, and a mistake to remove it. YES! That blue boat is an openbow, I designed these to look like our 20'6" cruisers. You will need to make some custom stuff for this boat, do you have access to machinery and welding equipment? Your boat looks like Stan built it as a Crusader (brand) and it really doesn't have a lot of material in the bottom. Grinding then adding stringers and material to the bottom will make it "more safe". How heavy is the motor you want to use?

    The dolly i'll have to build, you have any pics of yours or recommendations on things when it comes to building it?

    The hull does seam thin, i was already thinking about laying some extra layers of glass to add some strength. What would you recommend i use? Do i need to vacume bag it?

    The engine i want to say i was told is around 275 lbs.

    Foam under the bow ONLY, is NOT LEVEL FLOTATION. I saw no blocks of foam along the sides towards the transom, so I am guessing it never had level flotation. Inboards don't need level flotation, just enough flotation to keep one end up on top of the water. You can make a dolly out of two by fours, level it (front to rear and side to side) and then don't move it! Two bulkheads will never hold the shape of that hull bottom. The deck always helps hold the boat together, mounted correctly (straight) or not. How about two motorcycle chains on four sprockets for a 'V-drive'? It would be parallel, but light weight and strong. My 12' 2" boat shown on the Mag cover, ultimately went 62 MPH with a 439CC two stroke motor. I used a 'snowmobile clutch' but it was not strong enough to last. I finally went to 'two small block Chevy timing chains'. That made my deal 50% under driven. I was working with some stainless small outboard props when I had to move on to some customer's real race boats ($$$$) and keep the rent paid. I also did one with a Mazda Rotor and Berkeley "E" pump. The size, weight, price and power of that motor make it my choice of power for little boats. Then you throw a turbo on it and WOW!

    cobra1, foam does nothing while the boats at float, it when you sink it. Keeps the boat bobbing so it doesnt end up at the bottom of the river/lake.

    GFINISHLINE, i was thinking about getting a real v-drive unit. I've found some guys who have older ones (not casale) that only want 100-200 bucks for them. I've not seen any pics of them yet though.

    I'm going to have to draw out a dolly design and see what you guys think about it. The 2x4 horizontal bow and are week, i assume i would want these sitting vertical right next to the inner strakes?
