Prop upgrade.
I'm currently sailing a Gemini Legacy 35. Under sail on a broad or beam reach it is pretty easy to hit 8-12 knots but under power at 3000 rpm only about 5.5 knots if no wind. The engines don't seem to be in any strain even motoring into stiff winds. I was considering replacing the two blade props for the folding variety until looking at prices. I suppose the real question is can I go to three blade props on the Yanmar 15 hp engines. If so what diameter?
Thoughts appreciated
