Hi, I have a 1995 tohatsu 50hp Model: M50D, No power trim or starter, I am thinking on buying a 1994 Tohatsu 90Hp Model: M90A with power trim and starter. Now my question is: Can I swap the lower unit from my 50hp to the 90hp since the 90HP lower unit is no good. I try to find any help but I can't get any. I don't see anything different except the power trim, starter and oil injection system they look very similar to me. Any help I will really appreciated.<br />Thank you
