My c-dory 25 with a 135 honda came with a three bladed stainless 141/2 x 15 prop. I used that prop for a few years putting about 600 hours on it before trying a 151/2 by 13 aluminum three blade prop. I have put about 1400 hours on the new prop. Last week I hit a dead head and had to put the old stainless prop on and boy what a difference. The 151/2by 13 drives my boat SO much better. I get much better fuel economy, get much better boat speed at lower rpm's and get up on a plane easier and quicker with the aluminum prop. The difference between the two props was amazing. I carry a heavy load on board ( average 6 to 7 people) and that may influence my prop size. I'm wondering about going to a 16 by 13 as there is about a 1/16 of an inch clearance using the 16 x 13 prop....
Just my experience, thought I would share it
Bill.

From what you describe, you where getting more slippage with the 1&5" prop.

1 / 16" clearance is not enough-clearance ! The al prop flexes more, so there is more like 2.5" difference. On our 25 at Powell the best prop was an 11". Also check engine height.
