I am thinking of trying a Powertech OFS4 on my single engine Fountain Center Console. I need a large diameter 4 blade and the Powertech is even larger in diameter than a Rev4. I have been told that the OFS4 is kind of like something between a Bravo and a Rev4. I will need a 17 or 19 so I cant run a Bravo. Has anyone ever compared one to a Rev4? I can spin a stcok 19 Rev4 to about 5200rpm. Unfortunatley when I try a 17 Rev4 I hit the limiter at 5750.
