Though it truth its only the beginning...
first time out, tiny lake, barley nuf room to get going.
motor don't have power trim, tried hole 2, 3 and 4. 3 seems to work best.
i did not have a gps with, but hit 45 by speedo at 5000 RPM, with 14x19P prop.
i will bring it to the cabin tomorrow and test some there, that lake is also small but i should be able to let it run out some.
i will see what the other props are, and maybe try them, i have a stainless with no numbers :/
