force rpms.

Trying to find out what the top rpms of a 1990 force 120hp l drive would be, any help would be greatly appreciated

The prop you choose you should give you 5500 RPM with a light load (1 person, 1/2 gas) and deliver 5000 RPM loaded. Planing characteristics of your boat can also affect that. A doelfin/shark fin on the motor can also help in planing and poposing if you are marginal on power.
