Yamaha 40 Lower Unit

Tried to drop my lower unit to replace the impeller but it will only go about half an inch. Any thoughts?

Get a couple of die bars and try to persuade it off.You Tube video.

Still working it…

3 hours of beating stacked 2x4s with a rubber mallet finally got it done.

Would have been really easy if the shaft had not stuck.

Haha ,how did the impeller look? I changed one out on my Yamaha 70 and it was fine.Good job and I wish I could have been there.

Impeller looked good. Nice to know it is an “easy” fix.

Greased the spline so hopefully next time is a little more user friendly.

This guy has some good tips for the reinstallation.

Little update, motor would not pee so I dropped it again.

Impeller that was supposed to fit 40hp shaft is too big and kept slipping off the key.

Only Yamaha certified parts from now on.

Old one in the right…
