I had a new Yamaha outboard installed on my Four Winns 16' ft boat and the max rpm is 5200. I want to go down two pitch sizes and would apprciate some guideance.
Suggestions please.
The rpm range for the F70 is 5300-6300 rpm's at wot. Dropping 2 pitch sizes would get the rpm's to high side of rpm range, would gain 150-200 rpm's per inch of pitch.
