My SkiBoat resto project. *last update 17-2-09*
Hey guys and girls.
I just love tinkering so much I've got another project on the go.
Its my old mans skiboat, dunno if he'll be able to use it as much as he used to but My brothers and I sure will, and I think dad will be happy to hand it down to us...
So its been out of action for about 10 years, the sump ruster out and dropped its load all through the bottom of the hull, plus the floor was getting saggy in parts. Dad was concerned that the main stringers (wooden chassis rails) were rotten, but we had to rip the floor up to be sure...
First I went to pick it up and discovered the trailer was totally fvcked. all the suspension was mild steel despite the rest of the trailer being Galvanised.
the suspension had rusted to nothing and collapsed:
So it was out with the old and in with some new Galvanised leafs:
I also replaced the hubs and the axle will be changed in a few months too so I can get the right offset for commodore wheels
And soon enough she was a roller:
We towed her back to melbourne then stripped her and cut the floor panels out to expose the stringers and floor frame:
Patched a couple of dodgey bits in the hull whil the floor was out:
The stringers we absolutely fine which was really good news, some of the floor frame was a bit damaged from years of use so we replaced some sections and added some more bits of frame using mirboo (water resistant) for added strength:
Next I cut up some new sections for the floor using Marine grade water resistant plywood:
I put a layer of fibreglass on the underside of the floor panels to insulate the wood from any water that might get into the hull.
Then the floor panels went in, I put a few stainless nails in through the frame and stringers just to hold the floor in place, most of the strength is provided by the glass which as you can see covers the whole lot...
Flipped her over on the cup weekend to clean up the underside, Initially we thought there had been repairs to the hull as there were patches of bog type material.
When we sanded all the bog away we were shocked to find no repairs at all. It appears the bog was put on to fill patches where the gel coat may have flaked away or peeled off.
I simply sprayed a few coats of high build primer and sanded it back until it was fairly smooth. there are still a few wobbles but its under the boat so who gives a rats....
painted it in Poly 2 pak in a similar yellow. Looks like the yellow is way light in the pics but because it was still wet it looks funny under the flash of the camera. Its actually quite alot darker and almost matches the old yellow. I did go a little lighter as eventually I'll spray the whole boat and I want it to be a bit cleaner yellow as opposed to an orangey yellow.
Thats all for now, I'll keep adding pics as I go...the aim is to have it done for summer!
Update 1st Dec '08
painted the inside of the hull. looks a bit funny I think but it will look heaps better when I get some carpet down on the floor. Also got a pic of the old engine before I started pulling it down. I'll have more pics in the coming weeks as I will be doing heaps of work on it...

too late for the paint!! thanks for the offer though.
painted in a poly 2 pack. good for adhering to gelcoats apparantly.
We use the baot primarily for skiing with occasional wakebaording so we don't want a massive wake. It puts out a pretty good wake at low-medium speeds anyway.
one of the things which I'm trying to avoid is adding more weight actually. the boat is very nimble and we want to keep it that way, makes for good hooning and when you have a few tubes on the back....

lol a four banger would not pull a skier out of the water idle - 1500rpm. direct drive so I need the install pull of an 8..
Has always been and will always be holden 308.
just a fresh engine with tricked up dizzy, jetted up quadrajet and mild a cam.
nothing too flash... jus a solid reliable unit.
The Name will stay aswell, though you cant see it too good in the pics, It's "Lawless" and believe me the name suits.. this boat has broken so many laws its not even funny...
tis a 5 seater but we may change the the front bench seat to buckets, so that may change...not sure yet.

Whoops. Someone should tell dennis that, hes got 2 of them with RB30ET's - both with 800hp roller bearing turbos and external gates moahahahalol a four banger would not pull a skier out of the water idle - 1500rpm. direct drive so I need the install pull of an 8..

I'm guessing thats for ski racing?GeminiCoupe wrote:Whoops.

if you want to wakeboard and knee board at low speeds you need an engine that will happily pull at 1500rpm.
for ski racing you just need to get the skier out of the water/ doesn't need to be a good start as long as they get up...then its full noise...
rb30's would be sweet for a race boat...
I have seen a 16ft boat with a 202 but it was not very good..
V8 all the way.
Last time i checked the Gemini WAS running Daniel, so that means you can pump money into something else now
Yeah your right, they do use them for ski's. One of the guys went out with Dennis ages ago, he vowed hell never step foot on another boat since then. Mustve been fun haha.
A mate at work picked up a 351 with twin turbo's making 800hp out of a speed boat - needed a bottom end rebuild. $1500. I wonder if he wants to sell it....want me to ask dan?
