I searched my question on here before asking and cannot come up with the solution. I have a 1989 28 hp johnson and need a lower unit, I need a conversion chart of some sort to locate one. Somewhere I found info that a 25 to 28 hp ser. no 0432812 20 in. long shaft 1989 to 1996 will work, and I was hoping someone here could verify this info or point me in the right direction. Thanks in advance as always.
