thanx guys... very interesting 
I was going to ask about the altitude thing, but somewhere I had read that the Honda 40 doesn't need any adjustment for altitude. Mentioned this to a couple of friends and one mentioned another aspect I haven't seen yet in this thread... according to my friend there may be more prop "slippage" pushing water at a higher altitude. Has something to do with the O in the H2O being less dense than at sea level :roll: Anybody ever heard anything like this :?:
