Well I finally broke down and purchased my new Reliance 17 degree pitch prop and I have to say Wow what a difference. I have a 2007 Yamaha F150 on a 21'8 Century 2102 Inshore. It came with a some sort of standard 18 degree Stainless prop. It always seemed a littled sluggish and slow out of the hole, so I finally broke down and bought a new yamaha Reliance Series 17 degree pitch and boom! Now I can finally get my 6000 RPMs and another 10 MPH Top end. The old one only got me 5200 RPS and about 41 MPH. I must say that if you have a boat similar to mine you might want to research it because its like I re-powered the boat.
