Pulled my plugs today for the first time.Notices oil on The middle and PTO Plug.Front plug was dry...Any ideas why???Just got done installing power filter And ran it on the hose for about 2-3 minutes..Shut it down figured id look at athe plugs cause she was idleing a little rough.between 1720 -1840
insulators are still white and a little brown discoloration around the threads..Ski only has 14 hours on it..Just woundering if this is normal
for a 4-stroke watercraft..I know my 4-stoke pickup truck doesnt have oil on the plugs.

Thanks
Scott
