I was pulling my plugs to see how they were looking and found some oil around the nut part of plug on 3 plugs
any advise here. Is this a gasket issue?
Plugs looked good but not evenly burned. Each plug have a different amount of burn on it
is this normal?

Should have posted this in the forum of your boat model but that’s okay, it should get plenty of replies… So there’s oil on top of the spark plug? So when you pulled them it seemed like oil at dripped down on them? Did your air filters look okay and not oily as well?

Not sure about the burn on the spark plugs, I’m not an expert so I never really dissect every plug and compare them lol!
 
thanks for responding! I did not realize I posted in wrong area. I will re post!
It does not appear as of if oil dripped down on them. More like oil seeping in where they screw into the head.
have not checked air filter but i expect it to be clean.
Thanks again!
