If you want to improve the performance of your boat I recommend buying a well fit stainless steel propeller and, perhaps, raising the motor on the transom a bolt hole or two.

Another way to say it is a 14" 3 blade from Mercury may not perform the same (better or worse) than Stilletto or Spitfire etc. Before investing $2-300 for a new prop, you should tell us the weight of passengers, gear, fuel on board. At what height is the motor? How many empty holes are ther above the top set of bolts? 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT
