Fouled Plugs 02 RXDI

[duscarter]

I have two RXDI's and they both started to hesitate until they got warmed up. All grounds are good, so I decided to change the plugs. All of the plugs were black and a little wet. My boat's never look that bad after a season.

They were serviced at 10 hours and only have @30 hours on them now. I am hoping to get to the end of the season before servicing them.

Question: Is it normal for the plugs to look like that after 20 hours, and do I have bigger problems looming?


I replaced them even though the skis ran great after warming up.

Thanks,

Re: Fouled Plugs 02 RXDI

those 02 RX's are plug-eaters...what is worse though is the exhaust gasket design-they changed from a paper type gasket to an O-ring style and down here in our saltwater the corrosion eats up the thin water jacket in the exhaust pipe and lets water get into the motor...looks like you're in freshwater territory so maybe you'll be lucky

Mine never see the salt water, but it would be fun! I don't mind changing the plugs often. How many hours should I check them? Is it normal for them to be wet?
