I have a Merc 60 Bigfoot, 3-cyl outboard fitted with NGK BP8H-N-10 plugs. I
think my plugs look too "wet" much like the third one shown in the photo on
the NGK website.

Although the motor runs pretty smoothly. I running with a 130 degree
thermostat. What should I look at adjusting?

I'm hoping you'll get a response from one of the mechanic types who
frequent this place. But, until you do, you might try this place:

If it were my motorcycle, and I had a wet, oily deposit, I'd be thinking of
bad rings. If it were a wet fuel deposit, I'd be thinking carb problems.

Good luck!
