1990 Force 90 hp Dual Exhaust Prop

[Mike O Jr]

Hello, Does anyone know what type propeller I should be buying for my 1990 Force 90 hp dual exhaust outboard? It's mounted on a 1990 19' Bayliner Capri Cuddy. I have the prop off but only find the number 692265 on the hub. The performance was fine. The diameter appears to be 13" for the prop. I have yet to figure out how to measure pitch.

I own 1990 Force 90, mine is single exhaust and I can use both types dual and regular props. With dual exhaust props the prop hub is open, however it makes no difference for single exhaust motors.
As far as pitch, it is likely you will need 15" or 17" for the boat type/size you have. The goal is to pick the prop that allows you to run your motor 5000 to 5500RPM at WOT with your regular load out.

Thanks very much. I really appreciate the help. Good to hear from a Force owner. I've owned this boat/motor for 15 years, use it every year. Had the lower unit rebuilt 4 years ago with a new stator and impeller. Top end was rebuilt when I bought it. No complaints. Very easy for me to maintain.

You are terrific. Thanks very much for the numbers. You've accomplished more than I did by visiting a dealer. Happy boating to you.
