It's pretty simple, and doesn't take long, PROVIDED the bolt heads aren't rusted off. If you get in over your head, then take it down to be worked on.

then you can get another one, just make sure you put quick disconnects on the motor mounts

I agree, it says that engine is great for 4x4. Doesn't sound like it's a marine engine. I want an engine for marine use. Does "crate" engine mean it's for vehicles only or are there marine "crate" engines?

This ad is a little old, but I'd check to see if these were still available.

You speak the truth, I was told the HT 383 has .051 S/S head gaskets. There is a raw cooled one out by me that ran all last year a lot more then 2-3 times, I will check with him and call Sallee Chevy to get the real scoop on that. I do not and would not run raw cooling on a good engine especially one with some fair $$$ in it, I know many do.

Re: $6,000 for 5.7 engine work?
I don't want to get too crazy. I was planning on selling the boat after the season anyway (got my eye on a 336) so I'm not going to do much/spend big money. I just want to get it running again (right) or buy a solid 350 engine so when I sell it I'm not screwing anybody. If I can't figure out the problem is something simple like intake or exhaust manifold gaskets, I'll probably buy the new motor you guys told me about for $3500 + shipping. Sounds reliable, with warranty and an added 50hp. Hopefully I'll know more this week. Gotta love big wrenching in 105 degrees

Sleek1- I bought two of those engines last year. They run great, the only issue I had was the the power valves, and main jets in the carbs. The are shipped with 2.5pv, and I think 60 mains. I have GLM manifolds and Imco risers, so I was lean. I changed them to 6.5 and 64 Mains and they are now happy.

My question is, do you buy a new long block, a rebuilt long block or do a full rebuild of what you have?

Re: $6,000 for 5.7 engine work?
Well everyone, it appears the engine is now siezed. Throwing my hands in the air. Talked to a reputable (from what I hear) mechanic. 3-4K rebuild the merc 5.7 ready to run. A lot cheaper than the 6k I was quoted by the mobile mechanic! The down side is he can't even look at the boat unitl June 22! Plus however long it will take to fix. Looks like I'll be mooching off some friends for a good part of the summer. Good thing is, my buddy just bought a 37 Sundancer. I know he'll need someone to help with those lines. Thank you all for your help. It's good to know there are people like you willing to take the time
