I know altitude effects horsepower, but can it also affect prop slip?
I am running a 118c with a 150 show 21P yamaha prop. I am running at 4500 ' in elevation. I'm 4" prop to pad with a manual jackplate....
I get 44 mph at 5800 RPM. Basically 20% slip. Takes forever to get on plane. Doesn't seem like there is much bow lift either.
I think I should be able to get better than that, either by changing props, playing with set up etc. Thinking of going to a 4 blade...
Any suggestions?
Thanks
