[Pan84]

Hi everyone
I have a question about max RPM on mercury force 1987 85 hp. I have about 4400-4600 and 35 mph (1986 bayliner capri). What maximum rpm should be? And what propeller recommend for little more speed?
Thanks

WOT rpms should be between 4500 and 5500. Size/pitch prop depends on size/weight of boat, and the WOT Rpm you are trying to achieve. Post in the prop forum with all your info and they will help you choose the right prop for your set up.
