Re: overpropped vs underpropped
I agree with Minne. It's not just that you can't reach WOT, it's that at 2500 rpm you are asking the engine to do what it normally would at 2800 rpm (approx) with less hp so it puts more strain on everything. That's not a huge difference and your engine might do OK, but if you get into a situation where you are motoring into a stiff wind and large waves and you need to run near full throttle that is when you might blow a headgasket or overheat, etc.
