Re: Engine Knock or Clanking in Mercruiser V8 5.7L Valve train .. UPDATE
Find yourself a good Chevy mechanic. Put a water jacket on the lower unit, and let him listen to it. A really good mechanic can often tell you exactly what's wrong by the sound--at least an educated guess.
Working on a 350 or 454 engine in a boat would be a snap for a quality mechanic. You don't have to work over fenders and under hoods--and can get to them so easy.
As far as you having to push the engine so hard to stay on plane--invest $450 in a set of Bennett hydraulic trim tabs. Problem will be solved immediately. Have you ever noticed that all planing boats (Sundowners, Cigarettes, Fountains) all have trim tabs. They'd never get those long noses down without them.
