240 BR Rebuild

Post by Ytmsn » Mon Aug 29, 2016 12:08 pm

Hi ya'll
I just bought a 2003 240 Bowrider about 2 weeks ago and just joined the group. BB suggested I start a build thread and I think that's a great idea as hopefully I can glean a
little wisdom from you guys as I go through my project!

So the prior owner bought the boat new in 2003. He is a super nice guy but very busy and consequently going 12 directions at once. He kept it boat up for the first few years, then didn't winterize one fall and the block cracked. He spent a ton of money getting the motor replaced, and then during the fall of 2013 it happened again. Wasn't his fault ths time though, it was bad service. (long story) At any rate, it sat partially covered in a storage lot until he threw up his hands, ran an add, and I found it.

Again, I've only had it home for about 2 weeks, but I've already sourced several things. Other than cleaning and detailing, I'm not going to do anything until after Labor Day and things slow down in the boat world.

I started with the seats. They were pretty bad with mold and stains but I've got them looking pretty good now. It's going to need some vinyl work, but that'll come later.

Sometime in the next 2 weeks I'll take it to the boat shop and they'll pull the motor and strip it down to a long block and set it on a pallet. Then I'll take the engine to a builder to strip my pistons, crank, cam and such and at the same time do the heads. It'll get honed or bored, depending on how it looks, then we'll go back with new rings, bearings and seals. Then back to the boat shop to be reinstalled.

Next up will be to the fiberglass guy who will wet sand and buff the entire boat.

Then to the vinyl guy for some recovering and repair's.

And finally to the stereo shop for a new head, 6.5 speakers and LED lighting.

I'll post updates and pics as I go. It's gonna be fun!

Here is is the day I pulled it home from Texas

These pics are from day one. The first thing I did was order a cover and clean on it.

The interior was pretty nasty. I'll get some shots of what it looks like now and post them up later.

Curious from your description - are you going to try to reuse the same engine block? I'm not too familiar with how that might work. Can they weld cracks and save the block if they are minor enough?

I was thinking the same thing John. What engine is in this? Why not just buy a used or Long block?

Cast iron and aluminum are both a huge pita to weld, and I don't know that I'd trust JB weld, devcon, or even belzona when I was spending so much already on the rebuild. I thought one of the advantages to most marine engines was that they were built on cheap, common blocks?

There's no way I would weld the block. Too many things can go south by doing that.

Originally I looked into ordering a longblock. But my engine is low hours, so I figured I can use my pistons, crank, cam, and heads.

I have a builder that is supposed to get me a very low mile block. If everything specs within tolerances we can use my pistons and new rings and just hone the cylinders. If we can't find a block that will spec within tolerances then we may look at boring or going with something like a 400.

I thought about upgrading to a big block, but it would be too much trouble to change the outdrive, wiring harness, shift cables, etc. By the way, my motor is a Volvo Penta 5.7 gxi 320 horsepower engine. All of the Volvo parts hang off of the outside, the core of the engine is a 350 Chevrolet. I should have less than $2,000 into a new motor for removal, rebuild and install when it's finished!

Ok thanks for the update. Think you could spend that on a short block or long block and get a warranty with it. I'm going to check around I have nothing better to do and I live on cl. And eBay.

Btw, a longblock from Jasper Engines was going to be about $3,200 not including removal and installation.

Ok just a quick non stressful look on the inter web. I will also check with my brother.I know it's not a Volvo but he works at mercury and sometimes they have things laying around for sale. He sent me a list a bit ago. Alkali found a little jewel to wreck your budget.
