    I found this after my last run. Starboard side. It is directly in line with the dipstick location, but on the other side where there is just a plug.  The plug does appear to be leaking. It only leaks when running, which I am attributing to oil sloshing, boat angle, etc.  Is there a specific part number to replace a seal, or is it just a tighten it up deal? It appears to be quite a bit of oil.  There appears to be no additional leaking. Runs fine. I know its not super clean down there anyway.

    Thats exactly what i was looking for.  Thank you.

    Is the oil level at rest over that bolt, or can that be swapped without draining.

    Also will note this is first time it has done this,  and the motors sat for about 45 days.
