350 chevy from 24' bayliner trophy

[motoguru]

I just picked up this 24', 1985 bayliner trophy(I belive it's a 2460, correct me if I'm wrong). It has been in storage for the last 8 years, the guy said it was winterized before it was stored. It has a 350 chevy with a penta outdrive (I think it's a 280 but I may be wrong, has a duoprop too!). Me and a friend went in on this project 50/50 and I belive we got a decent deal. I've always loved boats and want to learn as much as I can about them. Kinda why I got this project.
I am thinking about putting a rebuilt 350 in it. The guy said it was running when he winterized it for storage. However, I would like to go ahead and put in a fresh motor. I have a few 350's I can use, they are 4 bolt mains(does it matter if they are 2 or 4 bolt?). I will be building it myself and would like to know if there is anything particular about the engine that should be tuned/built for a boat? Do I need to keep it under a certin HP? I dont want to build a major performance motor, I want it to be mild and reliable. I just know that It can easily get over the 225hp the boat came with. I would also, like to replace the seals and u-joints on the outdrive. is there anything else I need to do to the outdrive? Is there anything I need to know about these outdrives(do they have any week points or something that needs to be checked/changed often?). Also, as far as accessories, what needs to be "marine" and what does not(starter, alternater, hoses, belts, spark plugs, freeze plugs, wires etc)? I have some pictures in the link below.
Any help would be great. Thanks in advance.

Re: 350 chevy from 24' bayliner trophy

if ya can see? look at the stringers pretty close. or wherever yer engine mounts to before ya invest in motor parts. research parts availability on the drive. i got had on my last boat because i didn't have good wood to mount my front motor mount too. turned out i had soggy stringers and have a full restoreation on hand. for me it made no difference weather i had a new drive and engine or not. i had nothing to bolt them down to.
pretty much all acc. on yer engine are marine duty. don't mix auto parts on boats. its a bad idea. ya probaby picked out a couple of the less critical parts for not useing marine parts though. belts and wires. everything else, marine duty.
before investing any bread, ya might try and see if ya can get it to run with what its got. take'er out on some shakedown cruise's. you will start finding things that are in need of repair pretty fast that way. clean it up good too. every spot and everywhere. you will find items in need of repair that way also. least i have anyways.....welcome to the world of boats.....it's fun. if ya got deep pockets........

oh, and don't forget the plug....

The first thing to catch my eye is the Delco automotive HEI distributor. A big NO NO, it is not marine certified.

Re: 350 chevy from 24' bayliner trophy

i did the same thing, bought a boat to rebuild and asked alot of question quick. it came to getting rid of the project boat because i knew nothing about boats and wanted to. it got costly fast, and most costs and troubles were due to knowing nothing about boats.

i devised a new plan for a future project boat. i just bought a newer boat with everything in place since the day it left the assembly line. now i know where everything is, i can see what works and what may fail and i have the REAL manual that i need for it.

the conclusion i came to was to learn about boats first, then turn to a project boat when i know a bit more.........

i'm hoping this works for me because i'd love to do what your setting out to do one day, but the knowledge and money to do it with will have to come with time and experience.

nice boat, best of luck with it, you came to the right place for help. also learn quick......... marine parts only, you'll get a double lashing otherwise.........

Re: 350 chevy from 24' bayliner trophy

Not only is the distributor an automotive (and dangerous) so is the fuel line and inline fuel filter. Also a No-No on inboard engines. Then look at the carb, probably automotive also, never seen a marine carb with a manual choke as standard equip.
The REAL dangerous part I see is that positive battery cable going down between the engine head and exhaust manifold. The hottest place on the engine. When (I didn't say IF) that insullation on the cable burns off or wears off, you have a direct short to ground of an unfused battery cable. It will be exciting.
In the fuel pump picture, a piece of copper tubing stuck in the hose without all the clamps? ? ? ? Nice use of electrical tape to prevent leaks :% :%

Don,

What's the problem with the inline fuel filter?

I installed one in my boat because I was having trouble with the carb getting gunked up. I haven't had the problem since.

"What's the problem with the inline fuel filter?"



It will not pass the CG flame test and you would be suprised how easy they fall apart
