I have been thinking about this a few times off and on. Since we are currently talking about refillable 1 lb propane tanks
, this has popped up in my mind again.
I have a 5 hp Lehr outboard
but it is insufficient to bring my 310 RIB
to planning speed. Not surprising really ... but I am also not getting the full power out of the engine
because it never gets to anywhere near full RPM's. I am thinking of fnding a lower pitched propeller
but have no idea if I can just buy a propeller
off a rack someplace or if it has to be a Lehr propeller. Also, I have no clue what the appropriate pitch
would be short of doing trial and error testing with different pitch
propellers (I would assume the diameter to stay the same).
Any suggestions how to best proceed with this would be appreciated.
