Lower end water Johnson 1.5 1R69C

I changed the seal on the prop shaft and large o ring on the casing visable on removing the prop. #2 #3 and #4 on the pic at this link:

As this is a simple motor can someone explain how water is getting into the lower end?

Re: Lower end water Johnson 1.5 1R69C

you have a seal under the water pump#10,though its not shown on the parts list,#9 ,also check every surface that a seal sits in or rides on ,such as the shafts,the oil fill screw gasket#9,is the prop shaft nice and strait,if not it could leak,also check all castings around the water pump for possible cracks or corrosion.All that said,best way to check is to pressurize te unit with about 1o lbs and spray soapy water around leak possibilities.Either buy ,borrow a pressure pump,but you can likely make one from a replacement oil plug,drill and tap for a shrader valve,srcew a bike pupp to schrader valve and lightly pressurize,you may also put a "T"in the system for pressure safty and put a guage in the line.OR,have a shop do the pressureand or vaccuum test for you for a small???fee???

I just e-mailed to see if that seal is available, in the mean time I shall make a pressure fitting out of a spare drain plug and proceed from there.

Will post as I go.

Thank you for your advice.
