Default plugs look too "wet" (two stroke)

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

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


Ah - well then... :)

It could be a few things - plug isn't hot enough, you have an oil
mixture problem (as in running rich) or you need to clean the carbs
out. 130 degree thermostat is about right for that size engine.

I'd try the carb route first if it's running ok - run some carb
cleaner through it and see what happens.
