hey guys ... I have a 24ft pontoon with a merc 150 outboard . Current prop right now is a 14.5 4 blade 17 pitch . Have had the boat for 2 years now. Boat and motor is 2015 . Wot I’m running around 30mph at around 4800rpm . Problem I’m having is I have to be on pure glass water to get that result . Any type of sharp turns , or if the water isn’t ideal I’m get ventilation every time rpms run around 5k and mph sit around 20-21 . Also happens when I’m pulling tube off the back . I’ve had the motor mounted to the lowest spot at this point . That helped a little . Installed a whale tail on it . That also helped a little bit more . But still it continues to blow out the prop if conditions aren’t perfect ! Any suggestions on different prop sizes or trying something out would be appreciated. I was thinking of going to an even larger diameter prop 16 by 13 3 blade . Rpms should be between 5600-5800 by doing that I believe .
