Like it's 3-bladed predecessor, the Legend, it has become the top manufacturers choice as original equipment. The 4Force is the first 4-bladed prop created for tournament boats. It takes over where your inboard leaves off-showing its stuff at precisely the point where horsepower is transferred to the water.

The result is a ride of remarkable smoothness and steadiness, with a consistent pull and increased stability to satisfy even the most demanding skier.

I have 2000 MB sport boss 190 boat. I wanted to know if this was the right prop to buy. Can you help. My motor is a 5.7 PCM?
We do not have original information to confirm. You will need to to know number of blades, diameter, pitch, and bore size.
