Hello all, new here and need help. Thanks to all the great info I have gleaned from this site I am changing the water pump on my 97 Yam c115. Got everything apart ok (even the dreaded collar thanks an old post by Rodbolt) till it came time for the impeller which is stuck to the shaft. I've removed the rubber, sprayed it with some penetrating oil and been tapping it with a plastic hammer but so far it still won't budge. Now what?
Also when I removed the lower unit a small amount of oil poured out from somewhere up in the motor housing where the driveshaft goes up into, thought that was wierd. When it poured out it hit just forward of the shift shaft and some collected in the cavity just forward of that, then when I got the water pump housing off there was some inside it too on the wear plate I can't really seem to locate the source yet as I wiped it off and don't see any signs of it anywhere else, anyone know what is the cause of this? See pic below...Thanks for any help.
