Ok, I admit I do not know much about Yamaha's HPDI 200 hp motors. I am still in search of a new motor for my upcoming river jet boat and went to Deweys Cook Inlet today in Anchorage Alaska. I asked the owner what he thought of a 200 HPDI for my choice and he told me the motor will not perform in cooler weather and the only people who are happy with them are people who live in Florida. He said in Alaska's cooler summer climate (temperatures usually 50-65 on the water) these motors fouled plugs constantly. He even told me he hasnt sold one in over four years and the ONLY motor I should consider is one of there 4 strokes.
I used to have a 2 stroke Yamaha 150 and a 115 and both ran great. Is he yanking my chain just trying to steer me into a 4 stroke? Anyone up here run these bigger moderen 2 strokes?
