I have a 2006 Yamaha 50 2 Stroke on a 18' Pontoon Boat. The factory RPM Range is 4500 - 5500 RPM @ WOT
It origionally came with a 12 1/4 x 9 Yamaha Prop and and ran WOT at 5400 - 5500 rpms 15.2 mph w/ 2 adults and a teanager.
I then bought a Turning Point Hustler 12 x 10.5 and ran WOT at 4900 rpms 18 - 19 mph w/ same 2 adults and a teanager same load. Wich was kind of on the mid to low end of the RPM range.
So i then bought Turning Point Hustler 12 1/2 x 8 thinking it would jump my RPMs back up near the Yamaha 12 1/4 x 9 and ran WOT at 4950 - 5000 rpms 16 - 17 mph w/ same 2 adults no teanager same load.
Any info or help will be greatly appreciated
Thanks in advance.
