I have a Sea Nymph V13 with a Evinrude 1972 65hp engine. The prop currently on the boat is an 18 1/4 x 17. This was put on by the previous owner after he broke the original prop and it was a second hand one given by a local to keep him going.
From what I have seen on trawling the net I cannot find anyone suggesting a prop of that size for a similar size boat/motor.
Is there a calculation to give you the right size, pitch etc?. I understand that it can depend to a degree on what you are doing with the boat etc, I am only fishing, occasional slow pull round with a sea biscuit for the kids, general use, not going too far each trip, bit of lake use and sea use but obviously would still like to get reasonable power etc
Any ideas at all on what size prop I should be looking at???
