Need some help w/the removal of the water impeller. Here is what I have done so far.
1) Removed cover, hoses, etc. etc.
Put a wrench on impeller, twisted and it spins.
2nd try - held clutch did it again but nothing.

What the heck am I doing wrong??:bonk:
I am a little slow !!!! but this is baffling me.
The manual is not very helpful!!

Thanks in advance.

You may have broken the shaft by attempting to remove it that way. To do the job correctly, you have to remove the right side crankcase cover and hold the inboard end of the shaft with a 13mm wrench on flats cut on the shaft for that purpose.


Got a manual?
