What condition is the rest of the boat in - stringers, floor, helm, steering mechanisms, etc. You can't tell much of anything by the cosmetic condition of the hull. I think you need to have a good understanding of the overall condition before deciding what to do with the engine.

If those other parts of the boat are good, I think I'd look at a rebuilt engine. I'm not sure you'd be able to know whether that one's good for a rebuild without tearing it down.

Oh, OK. How 'bout the drive? Sounds like a nice project.

Do you plan to use the boat a lot? I still think I'd at least check the cost of a rebuilt motor. But that's more a statement about my philosophy about things than it is about your existing motor.

Well, whatever you do, DON'T use the sledge on your drive :roll: .

Your trim pump motor is probably shot, or the connections to it are corroded, or the fuse or breaker on it is blown/tripped, it's out of fluid, or all the above. That's OK, you're tearing this thing completely apart anyway, that's just another part that needs done.

Agreed. Hopefully it isn't a complete loss and you can get it back in the water.

If you have to replace the block, they changed in 91. You have to get a kit for the retro, but you can get a new longblock with distributor and fuel pump for $2600.

I did mine last year and I am glad I got to tinker around. I have more in it than I could sell it for, but She is perfect for what I wanted.
