proper prop pitch
is there any reason to worry about proper pitch?
Certainly. Under pitch the prop, and over rev your engine. Over pitch
the prop, and overload your engine.
Your engine should have a " recommended " rev limit. Pitch the prop to
get close to that figure, and your fine. I changed from a 16 pitch to
an 18 on my Chris, and get more top end, but now my trolling speed is
a little too high.
