I'll Bet Anything...

thanx guys... very interesting :P

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 :?:
 
I don't think that you will find that prop slip is greater at elevation--it is decrease HP. I figured 2" pitch for each 3000 feet.
 
Here's a bit more... and it seems to me that the elevation thing seems to fit right in with this:

Spent the weekend at Flamming Gorge Reservoir (fishing for Kokanee). Elevation was reading just over 6K. Lost another 100RPM and top speed dropped to just under 20MPH. Interesting.
