Prop for Older Johnson OB

[FishnTechGuy]

What is a good fast prop for a '77 Johnson 85EL77?

First off, welcome to Fishing Minnesota!

This is dependent on several things...

First off, based on the model number I'm guessing you have a 85 Hp motor?

Anyway, sizing a prop mostly involves where you're at for RPM's at Wide Open Throttle (WOT) and what your max WOT RPM rating is for your motor.

Do you know where you're currently running for RPM's at WOT?

Other helpfull information is if you're happy with the performance today (holeshot, top end speed, etc) and what pitch prop you have today.
