have a 25" shaft and want to convert to 20" shaft. is it as easy as getting a 20" shaft lower unit or is there more? How hard would it be to convert the 25" lower unit to a 20"? any help is appreciated

Dont know if the newer motors are any different, but old Force needed mid section, shaft, water tube, shift rod.. I figure an optimax mid section wont be as easy to come by used as an old motor like I had. Good luck with the project.

Dont think i would need a mid section. There is a 5inch spacer section above the lower unit below the mid section that i could just take out
