Hi All As my engine sits on the cabin floor over the winter while my mechanic waits for spring to reinstall it, I'm thinking maybe he should have removed the manifold and cleaned it out. The mixing elbow is being replaced already due to corrosion, and there is rust visable on the interior of the manifold. The surface had some light rust which I've sanded off, primed and painted. The drain petcock is frozen. The engine never ran hot last season, however the zincs were completely corroded by the time I got around to checking them. Is it advisable to pull the manifold off now, or should I leave well enough alone? Is it likely that the manifold could be damaged while removing it? Or are there less invasive ways to flush the system? Thanks for any input. Larry

Manifold bolts/studs/nuts
are likely to be frozen. If you break them off, do you have skills, drills and easy-outs to remove the stubs? You won't damage the manifold unless you are a total animal! ;D

Ditto that
As they haven't made these boats in a long time, I am assuming this one is close to or over 20 years old. Ditto what was said previosly, about the bolts more than likely being frozen in place. The flip side of this is, would you rather crawl down into the engine compartment, and attempt to get them out, and fix the ones that twisted off, or would you rather do it while you can get to it. I would do it while it's out. At least if it's OK you will know it, and be able to get it off later if needed. If you remove, be sure to coat the new manifold bolts liberally with never seize.
