Boat propeller

[Mike Redmond]

Bought a new propeller for my 15 hp honda,original was 9 1/2 by 9 1/2 ,,got a new one 9 1/4 by 9,,hoping this will slow down the boat a little bit for trolling,hoping I was right,havent tried it out yet,was told I would loose some at top end but should be a bit slower for trolling hope I made the right choice,,,any ideas?

I don't know how much slower you want to go but going from a 9-1/2 pitch to a 9 pitch reduces your top and bottom end speed by only 5%.

The most common fix to trolling too fast is to add a trolling motor. You can also drag an empty 5 gallon bucket through the water to slow you down.

You would need to go down to a 6 if there even is such a thing to make any real difference at idle.
