Hello, I have a 2001 Hunter 460 with the flex-o-fold prop, previously my WOT was around 3600rpms. This put my cruising RPM's at around 2800. Over the last year i've noticed I can no longer get up to 3600rpm's. I top out around 2900. Thinking this could be because of a running gear or bottom growth issues I had the boat hauled, new bottom paint, running gear inspected (nothing looked out of the ordinary). I'm still not able to get the RPM's above 2900. I had the engine serviced, oil change, fuel filters, valve timing, belts, etc etc. After performing the engine service i'm still unable to get above 2900rpms. Does anyone have any other suggestions? Are there adjustments I can make to the throttle cable? I've heard they can stretch and or may need adjustment from time to time. Any suggestions would be greatly appreciated!
