4 Tec Misfiring

[alldodge]

My 07 Seadoo started loosing power and the longer it was run the worst it got. Slowly managed to get it back to the dock and looked at the plugs which looked OK. Checked voltage, and looked but didn't find the fuel pressure test point. The filter is in the tank as part of the pump

After reading some other threads looks like its a common problem after so many years/hours that the plugs go bad. Even found some new plugs are bad.

In any case ordered 6 plugs (DCPR8E, only need 3) from iboats and will put them in when they arrive

I have a pair of 06 GTI's and just experienced the same thing with one of them. The plugs looked fine, but I installed a new set of plugs & it is now running great. I have read it is a good idea to swap the plugs every year.
I'm going to change plugs on the other one too, just to keep them on the same pm cycle.
