OK Boys, here goes: Got the boat home last night after a very long trip from Cape Cod. Anyway, let me take a step back. When I test drove the boat a couple of weeks ago, I got 4900-5000RPM's max out of the set up. The boat has a Tee Top, Whaler Drive and it had the front Curtain installed on the Tee Top (Lots of Drag) The boat seemed to plain easy..ran fast (Mid 40's), but was stopping just short of 5000RPM's. At the time I was wondering what kind of Prop was on the motor. Last night, I noticed that there was what seemed to be a 21" pitch Stainless Yamaha Prop of the rig. The only designation I could read was on the side of the prop with a letter then a hypen then the 21. I assume this means 21" pitch. Yamaha shows specs for this motor such that the Max RPM's should be 4500-5500. Also, I thought I read that Max HP is made at 5000RPM's. OK, finally for the question: Would I benefit by going to a 19" Pitch prop? Oh yeah, let me know if the Letter-21 mark on the prop may not indicate 21" pitch. Thanks guys, John from Madison, CT |

The letter-21 does refer to pitch. I recommend trying a 19" pitch for increased rpm and better performance. |

John- I agree with the boys- toooo much pitch at 21". I run a 225 with a 15x17", goes toward mid 5,000rpms. Screams, plus perfect to pull wakeboard crowd, cruise or fish. .03 David |

John, for rough comparison purposes, I'm running a 17" pitch on a 22 Revenge WT powered by a 225 Yamaha OX66. WOT is about 5300. The dry weight of a 22 Revenge is about the same as 22 Outrage WD. However, you have the T top which probably adds more drag, particularly with curtains up. 21" pitch, even for a 250, is too much. Drop to 19" to get your rpms up over 5200 when lightly loaded. |

Guys, Thanks for the help. I bought a "used" Yamaha 15 1/4" x 19" Saltwater Series SS prop from a Yamaha dealer. Only saved 20% off List but needed one. John |

Boats in WATER !! Took test ride with new prop.. Gained 300RPM's with this (15 1/4 x 19") Prop at WOT, now 5200. Expected 400RPM gain but realized that prop has larger diameter by 3/8". Top Speed is 44MPH (Light load) but with Front Curtain on Tee Top. John |

Reelescape1, I was told that he Whaler drive, not only adds weight (~300lbs.) but also bleeds some speed due to wettable surface. I am thrilled with the ride. Feels like a much bigger boat than 22'. With bow pulpit, and Whaler Drive, she LOA's at nearly 26' !! John |
