I have a 16.6 ft lund with a 90 hp yamaha four stroke .
The dealer set it up with a 17 pitch prop and full of gas and two fishermen it runs 35 mph 5000 rpm .
Yamaha owners manual says the RPM's should be 5500 to 6000 when wide open . And their prop charts and Mercurys prop selector put me in a 23 to 24 pitch prop .
If I increase the prop pitch from my 17 to what they recommend wont my rpms be even lower ?
Should I strive to match the recommended RPMs and lower my pitch or what ? ? ?
Don't take me wrong, I'm not anti-technology. Battery powdered items will always have their place. I'm mean you don't want your girl friend or wife in the bedroom playing for their gas powered adult toys!! That would be a bit loud and smokey!
That’s right. My 84 year old dad loves his electric chain saw. Light weight and quiet. Besides, at his age he’s not cutting a bunch. Where as myself I want something with more power and heavier duty. Look at how many people have switched back to gasoline cars after running one in winter if you travel a lot.
As long as my strike master works I’ll keep using gas. Maybe my next will be electric, but who knows, you can find used gas ones pretty reasonable as others buy electric.
