Ok I need a 20mm shaft 27 1/2 inches long. It needs a 1/4 keyway 2 1/2 inches long and 3/4-10 threads on other end 3 inches long. Seems MB used stainless; I would be ok to use chrome molly or even tgp precision shafting, just as long as it is cost effective. I got one estimate from machine shop , it was like $500 using SS boat shafting. Thanks for any help. Sucks MB does not sell parts fo these models anymore.

Your tellin me Mud Buddy does not make and offer parts for a machine that they built? What year is your motor? Have you contacted MB directly? Duckdon

They do, but it is a complete replacement, meaning shaft plus housing. Thats a $600 shaft replacement. I got lucky and found a local machine shop that does shafts for longtails and they will fix me up with drill rod instead of stainless, suits me fine I run fresh water . I know stuff breaks and it costs to run a MM. But my pockets not so deep nowadays. So machined shaft will costs me half. So I am good to go now...........
