Can air in my raw water strainer have an adverse effect on the rate of flow of sea water into my water pump? I've checked all hoses and seacock for obstructions and found everything clear..no kinks, no foreign objects. Right now, all I get from the raw water side before it enters the impeller is a moderate trickle. Secondly...how much exhaust water should be exiting my exhaust at, say, 1000 rpm? It is hard to find a definitive quantity, just lots of adjectives, like steady or sufficient. Thanks...
I think that it can.
I never figured out why but with my old engine and water intake setup, the engine would sometimes overheat when heeling to starboard.
It did this once in a very precarious situation and caused a great deal of grief.
I bypassed the raw water strainer and it solved the problem.
I suppose it was a vapor lock or something.
