I have a 1968 Sweet 16 with a 302 Ford that puts out about 300 hp with a Volvo Penta Hollam and Moody, and I am only running about 50 mph on the water. I need to know what size prop to put on so that I can get up to about 65 mph on the water; with still a good hole shot. Anybody have any suggestions?

I sell SS props that work very well, but that combo will not go 65 with that power. 58 on a good day

What you did not mention was the size and type of the prop you are using now.
