Picked up my new ride today!! It has the 150 SHO with 4 inch Atlas JP and a Yamaha SHO 22p prop. Got the initial two hours of break in done and ran another half hour before loading it up. Opened it up and hit 59.2 gps trimmed half way up and the jp all the way down and hitting 6,000 rpm's. I'm thinking I may need a 24 p prop. The boat handles great!
