OK Mates, I got this impeller kit but I can't figure out where these O rings go, none where on there when I disassembled it. 1997 Mercury 3 Cyl. 90 HP Sr# OG539183
Thanks, Ed
Those WP kits were made to service a lot of motors.They found it easier to include all the parts and not have a million part #s .So just save them and don't worry.J
OK, but most of the illustrations on replacing the impeller there is a seal on the shaft above the housing and is removed and replaced, but there was noting there when I removed the unit.
So it dose not need anything on the shaft and I replace it just the way I found it?
If you're referring to the seal that sits just above the housing. It referred to as a 'slinger' seal. its for keeping any gunk from sliding down the shaft and collecting on the top of the housing.
Since it didn't have anything in the first place I figured one of the rings would not hurt it, so I did install one and lays on the cover and she pees just fine.
Thanks all, Ed
