says that this tranny has a 2.63:1 ratio for "right handed rotation" and a 1.95:1 ratio for "left handed rotation". As far as I know (and unlike Yanmar) they do not say which one of the two ratios is "forward" and which one is "reverse"
One boat I know has a right-handed propeller
so that when it goes forward the 2.63:1 ratio applies and when it goes astern the 1.95:1 ratio applies (this means that with a fixed-blade prop chosen to go forward you get lousy rpm
Another boat *seems* to have it the other way around with a left-handed propeller
so that when it goes forward the 2.63:1 ratio applies and when it goes astern the 1.95:1 ratio applies. This means you need a smaller prop to go forward and it is more balanced forward vs astern.
My crazy question is: Is it possible to use this transmission
either way or will it suffer if you use it to go forward in the "longer" 1.95:1 ratio using a left-handed prop?
I look forward to some wisdom.
