My neighbor bought a new Tritoon powered by a new 150 HP Mercury a nice looking rig. He brought it down from Canada. When he started to use it, in the 25 mph range it would start to over heat and the alarm would go off. So the motor was lowered and that took care of the heat alarm. OK thought the problem was over. Nope now when adding more throttle to go faster he can hear the motor revving up but no speed in cease. He said it sounds like the motor is cavitating so he puts on a new prop 4 blade prop same problem. My observation is middle pontoon is creating an air pocket causing the problem. My thoughts are the motor should have the longer shaft to get a deeper bite in the water. I am not sure how much experience his dealer had powering Tritoons.
Looking for input on powering Tritoons .
