I do about one Yamaha service a day. every keyway I have to grind down to fit, and from the bottom side of the impeller I have to grind a little, without touching the top (of impeller)to slide down the drive shaft that I polish and us a light oil on before install the impeller !!! and about 1/3 of any model/horse pwr has a melted pump housing on top of the "cup"... I now also tell my guys to go to the ramp and bury the transom, and start with a quick jab on ignition...any clues as to why these units are so tight ??

dunno.
I watch some of my fellow techs fight them.
its very rare I do.
I have modified a chiesel specifically for key removal.
I use a 32oz ball peen and my tool.
I smack the bottom of the key in ,holding the chiesel horizontal.
then I place the dulled chiesel vertical and drive the key down and out.
if you do it for a living,learn not to fight it.
make that tool.

tight fit
Sir rodbolt,, that's more or less what I do myself....I have got it down pat !! but still think Yamaha should address this pain in the ass issue,, for what they get in cash for their parts,, one would think that they would fit better IMO...Of the 1000's of pumps I have done over the years,, I would say the yamaha's are a Tight fit !!
