Hello,
I?ve just purchased a Honda 20hp outboard for my 27-foot sailboat. It came originally with an aluminum 4x9 1/4x10 propeller. As I was sure this would be too much of a pitch for a sailboat, I ordered a spare 4x10x7 5/8, power thrust propeller. This is the standard power thrust propeller model for this engine and, supposedly, the the one with the smallest pitch. The problem is that 7 5/8 pitch seems to be still too large: At WOT, the engine reaches only 4700rpm(while I run at 6.8kts). My question is: Since I rarely reach such high rpms (I usually run at 3000rpm) would I be damaging my engine by keeping this propeller?
Thanks!
