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.
