I have a 13 OBV with a OJ 14.25x14 and from what I have been reading many are using the Acme 1433/1235 ( i have to measure for clearance on trailer before I go to the 1235).

By the numbers it seems that the OJ would provide the best low grunt especially compared to the 1433 (smaller Dia and higher pitch). My prop seems to be fine but it is the only prop I have used.

I am thinking the difference performance was will not be noticeable but noise and vibration will be reduced. Is this correct thinking?

Also if the 1235 fits is it worth the extra $50. I need a spare prop and figured if I could upgrade that would be a bonus.

I run up 1500-2200# ballast and have up to 6 in the boat, so I run a bit heavier.
