hummmmm that would be a bad little dive boat for around here.... seriously though the military has the convenience of using those on a mission or two and replacing motors so who knows what long term effect is. Nothing like the reliability of the 70hp 2 stroke yammi commercial engines
Many different motors have been used over the years, Merc's ,Evinrude's and Mariner's.
I have a 50 merc with a prop on this boat.
Cheers, Don
