I have a Merc 60 Bigfoot, 3-cyl outboard fitted with NGK BP8H-N-10

think my plugs look too "wet" much like the third one shown in the photo

the NGK website.

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

Four stroke? If you, you've got a problem if it looks like that.

Maybe a valve not closing or oil leading past the rings.

Sorry.......... damn, I knew i forgot something....... two stroke

If it is wet with oil, you are either running over rich or with the
wrong ratio of fuel to oil. That engine probably wasn't meant to run
with resistor plugs, but I doubt that would hurt, either.

When did it last run correctly? What changed?


It ran great last summer. Admittedly it lacks a bit of power this season.
Could the gas be sour even though I used stabil? I am so accustomed to
looking at plugs on four strokes that when I saw those wet looking plugs I
was shocked. I double checked and it is the right plug for that model
engine. So in answer to your question.... what has changed is that the gas
has "aged." I will let it run down and refill with fresh.
