prop selection for a 2:1 ratio drive?
i have a 1979 24' pantera. pulling out the 540 and putting the rebuilt 454 330hp merc engine back in it. i've gone through a few trs drives with this motor. i'm not looking to go super fast anymore as the boat is older and outdated. i have a tr drive that is in brand new condition and i want to run it. i know it's like 2 inches lower then the trs. i will be going from a 1:5 ratio to a 2:1 ratio with a 19 spline shaft. does anyone have a good idea of what prop i should be looking for to get started? i'm sure i will have to get the boat in the water to know for sure what prop i need but i need a base line idea of where i should start. thanks again for the info you guys gave me on my last post.
