I have a 90 HP Evinrude 90 SPL on my 16 ft 1997 legend bass boat that I just purchased. It has a 13 1/2 24p Raker prop. What is the factory prop size for this motor? The boat didn't come with a tach so I don't know how many rpm it's turning but it's slow to plane. Once planed it runs well both my father and I are big men and it consistently runs 40 mph.
I just want to get the boat to plane faster, and want to try a 4 blade Renegade what size do you suggest? Thanks for any info you can provide!
