Re: mercruiser manifold leak
Where is it leaking from? If it is leaking from a drain or hose, tighten or replace the clamp. If it is leaking from the gaskets, replacing the gasket is easy. If it is leaking from a crack in the manifold, then I would fix it first, 'cause when I didn't, I burnt an exhaust tube (very scary - smoke everywhere) and hydrolocked my engine!
