I have twin 150 4 strokes on a dive boat so I push a lot of weight. I can run on plane about 3200 rpm before I start going to fast for conditions. My props are 15.25 X 15 P now and I also have some 15.5X19P and 14X21P props from my old motors.I would like to increase rpm without increasing...
I had late 90's Mercury 150 outboards and I now have 2004 twin Yamaha 4stroke 150's can I use my old Mercury props on my yamaha outboards ? Are they generic in that they will fit most brands of outboard engines ?
