Well, I couldnt get my engine to turn over and I got a little emotional so I just yanked out that Merc 350 and will begin the rebuild process. Let me be the first to say its no party getting that heavy old thing out of a boat that stands 12 feet tall on the trailer. <br /><br />I'm thinking of replacing the heads with regular auto heads. I know there is a differece in chemicals used in marine heads, but as long as I stay up on the flushes I should be okay, Yae/Nae?

Re: Fed Up

No differences in the heads, just be sure any freeze plugs are brass. I don't know about chebbies but ford has a zillion different combustion chamber sizes. That as well as your piston choices will affect your compression ratio.

Re: Fed Up

ok, ready for some humor?<br /><br />My boat on trailer is a little over 12 feet tall. Dissasemble the engine all the way down to the block. Get rid of anything that adds weight to it. Then, secure a chain on each side of the engine with the bell housing bolts/water pump bolts. Using at least two people, pull out the engine and set it down up top.<br />next, attach another two ropes to the engine, and run the free ends to the back of a truck or something. You will use this truck to back the engine down off the boat kinda like a pully system, but use thick blankets to protect your boats fiberglass. <br /><br />Be very careful. the block w/pistons in it weighs about 350 lbs. Its heavier than it looks. <br /><br />oh, a bit of advice: Drain the oil from the pan. I was craddling the engine while two of my buddies had the chains. Naturally, where do you think the oil from the crankcase ended up once the engine was tilted? All over my shirt, and all over the deck of the boat.<br /><br />Its a fun little project but be careful...
