I Have A Sweet 16 That Has A 200 Bridgeport Motor That Has Been Rebuilt. My Compression Is 151 Psi Across All Six. I Also Installed A High Performance Tuner And Boise Reeds. I Was Pushing A 19 Pitch Prop At 6k Or More Rpm's. I Bought A 21 Four Blade Prop And Seem To Be Pegging The Rpm Gauge On 7k. Can This Be Possible, I Mean The Boat Is Flying But It's Hard For Me To Believe That I Am Able To Turn So Many Rpms With A Four Bladded 21. Does Anyone Have Any Experience With Proping A Sweet 16. I Was Told That The Motor Is Pushing Around 235 Hp. Like I Said She Skreems With That Tuner And Drilled Out Exhaust. Just Find It Hard To Believe That I Would Need Maybe A 23 Pitch Or Bigger.

Are you running a exhaust thru-prop hub propeller? You should be running a 25" pitch or possibly greater. A high performance propeller of some sort. Check out this link...
