i just bought a 14' Fisher SC Aluminum boat. It has a 2001 mercury 15HP 4stroke big foot outboard. I drive it from a side console and have most of the weight in the front of the boat. It barely planes and tops out at about 9-11 MPH depending on load and water condition.

I know the big foot is not the ideal motor for this boat but its what i have and i can't afford to get get a new motor. I believe it has the stock prop. it also has the planing fins on the motor.

would swapping the prop out help with speed? i don't know much about props. what would be a good prop to switch to? any other things I can do to help speed upa bit. top speed of 15-17 MPH would be nice.

Thanks
Jeff
