Thanks, I did find some old mod posts. I just upgraded my prop from the OEM ( I assume) 14 x 18 1/2 to an Acme 1433 and I expect huge results. I'm not real qualified to even be judging the wave because of lack of experience and skill, but after a couple of seasons of tweaking I always end up at the same speed and trim with my ballast and suck gate. I guess I need to recruit an experienced surfer on Lake Livingston for an opinion. Might be as good as it gets with the new prop.
