finding the right prop

[shine]

my motor is 2.5" higher than bottom of transom, no issue there.

Have decided to go with a larger diameter 3 blade 15.25" by 17 pitch. the 4 blade I tested was 14.5, so I am hoping to get a little less slip.

To this point I have just been trying to find a prop that will match the boat/motor well enough to operate. Assuming I have done that now the big 3 blade 17 pitch, I want to now dial in the fuel efficiency......Ordered a fuel flow meter, it does not make much sense to spend a lot of $ on props and and gas when you dont even know the efficiency of the changes your making
