Re: 1995 75 hp force lower unit
Physically, the Mercury designed Force 70 and 75 have the same lower unit. I don't know if the gear ratio is the same. The late 90s Force 40 may also use the same lower as the props on all these engines are the same as the Mercury 40. Again, I don't know what the gear ratios are, and I think the 40 uses a different shift linkage. So, I would not think too much about substituting a 40 lower unit.
