..... Do you recommend changing the port engine to ccr? I will be buying props anyways mine are in bad shape. or just keep the both in cr and buy new props?????
IMHO,
if you are satisfied with the boat's performance now and there are no unusual engine noises with good oil pressures and the drive-oil looks clean,
i would send out the props to Throttle-up or B-Blades and have them either fix or recommend a new set-they are great peeps and wise. This would probably be the most cost effective way and with the right prop tweeking you may pick up a few mph.
FYI, I had a Nova as well and a bow lifting prop worked much better for me (ie:Quicksilver Lazer 21's) than the stern-lifters (i.e Hydromotive) but that was in the mid eighties and technology has changed quite a bit with prop work and labbing.
Best of luck
btw, the drive is what determines the rotation.
