Re: Steam from 454 exhaust
Ok llerrad<br /><br />We got hot manifolds. Now, cuple of things, crusader has the best design for manifolds and risers, such that, unless you take a sledge hammer to them or let them sit in sea water for years, rarely will you have water falling into the exhuast ports. They are far superior to Merc setups. That being said, How old Are the mainfolds? Are they original Crusader manufactured manifolds or are they the ever popular and far less quality Osco brand? 8 years is about the max they will last in fresh water. You can try pulling the riser off first. Rust builds up here quit a bit. Relpace the gasket with the hole in the gasket at the top position. Don't try to make holes in the gasket for the other 4 passages. Next, You say you replaced the impeller, but how old is the raw water pump itself? The seals on the shaft go bad, and a good way to tell is if water is leaking out of the pump behind the pulley. If water is dripping out steadily, replace the $250.00 Sherwood raw water pump. You mentioned that flow is low on this engine, so here's where I'd start.<br /><br />Good luck.
