Hi again, fishing season over, and the usual Before Winter overhaul of my merc 200 20hp 1972 revealed:
Almost only water came out when I drained the gear oil, seriously 99% water!!!!
It had dripped some oil when stood on stand, wich alerted me of possible leak!
No leakage through screws/ventscrew, so I turned it upside own, and it seems the new waterpump housing won't "clamp" down on the drive shaft enough to prevent leak.
I installed new waterpump housing and impeller with help here from the forum, what can I have made wrong?
Did I forget something?
Is there any remedy?
My driveshaft is of course corroded and no longer smooth where the tight seal should be, but it's micrometers we're talking, of coroded surface.
The spring loaded seal in the bottom of the waterpump housing is new with the new housing..
Once again I hope you guys can give advice how to (cheaply) save this still very functional outboarder?
