On my boat I use a 15 1/4 X 15 it has a lot of torque and works well for me.

Do you have a Hydrofoil on the motor?? That helps alot!!

Are you sure you are getting full throttle?? Make sure of that first.

My mariner alowed me to talk to them, then they recomended a prop, they let me try, if no good and still perfect they would swap for the next size till I got what I wanted. I used 3 props.

Over all a 14 1/2 X 17 worked, but I always felt like I was spinning my tires when getting out the hole.

Thats when we found the 15 and now out the he great!! little slower on the top end, I use o get 40- 43 mph now I get 36-40 depending on the load.
