I would appreciate any suggestions on what type of prop to select. Will run at approximately 5500 feet elevation with about 700 pounds of net weight inside (includes about four people and gear). Cruising and towing the occasional tube or skier. Thanks

With a load, I would drop down to the same make/model but in a 10.25 x 13 size. Given you are at elevation, you will suffer a loss of hp. I would go for a 11" pitch. Mounting should be two holes up. http://www.whalercentral.com/articles...cle_id=106 Get a tach. 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT
