Well I took the boat for a spin the other day (17 foot Tracker, 40HP Force (2 stroke, 2 cylinder), and something seems off. If the tach is correct, which I'm not sure it is, I'm going to blow this motor. It was reading over 7000 rpm (5200 is normal) at WOT. Anyone know what the idling RPMs should be? I'm going to see what the tach is reading tomorrow at idle and see if its close to a normal range.
So the tach reading was the first thing that got me thinking. Second thing was that I had the prop "runaway" on me one time after throttling down and opening it back up again. That usually means you're under propped right?
The prop that's on it is an 11 pitch. I'd guess that's a little low, especially considering the get up this thing has out of the hole.
I'm not sure of the overall size.
Any suggestions?
