Will not reach top speed

Re: Will not reach top speed

That will only remove the valve cover, the valves are a part of the head and the head is mounted to the the top of the engine block. the "head" and "block" are seperated by the head gasket, and that is where you have to get to in order to see the problem. Also, keep in mind if you are going to remove the head, you are going to need a new head gasket, they are NOT reusable.

OK, thanks for the info Poppa... my first thought was that gasket they referred to on the valve cover was the head gasket. I am going to at least take my boat in to get an estimate and see if I can/want to do it myself.

Re: Will not reach top speed

Just talked to the mechanic and it is, in fact, a blown gasket. They of asked if it had overheated (which it didn't), so I'm still a bit unsure of what would have caused it. I wouldn't think that the outdrive going south of cheese would have caused it... the previous owner seemed to do very little in the way of maintenance (oil changes and winterizing) but am unsure of what else could cause a blown gasket.
