oil trail-1993 yamaha 150hp

[mjdtofino]

still trying to familiarize myself with my "new" engine--I have a 1993 150hp yamaha V6 2 stroke outboard. I was chasing down one issue and while I had the engine cover off I noticed an oil trail coming from one of the plugs and running down the engine. Any ideas what this might be and how to deal with it? BTW I know nothing about 2 strokes at this point!

thanks

most likely 1 of 3 things.
1 plug seat is dirty.
2 plug was not torqued properly.
3 gasket is crushed and wont seal.

I would remove the plugs, carefully clean the seats and install new plugs with a torque wrench.

thanks, those are the kind of fixes I like to hear!
