It was raining when I wrote my previous post, but it stopped, so I went back outside & repeated the test at 2PSI. No bubbles at all…
So I became convinced this must have been a fill port plug that wasn’t sealed well enough.
But then I got to thinking: If there were water in my gearcase, that would be the limit of my issues. But I have this foamy wet oil up around the upper seal, so that made me think that was the spot where the leak was. I cleaned most of it out before I started taking pictures, but here’s an example:
So I re-pressurized and added soapy suds to the shaft seal and the shifter o-ring. Nothing. Not a bubble to be found. It’s not shown, but I lowered the pressure to 2PSI…still no bubbling. I’m a bit stumped.
O-ring soapy…no bubbles:
Upper seal soapy…no bubbles
Thoughts?
Or just re-fill with new oil & see how it goes next season?
Also, there’s this:
Finally, you may want to consider using some of the better OEM lower unit lubes that are made to “absorb” a certain amount of water without losing much lubricating qualities.
I’m all ears. Any recommendations?
