Losing revs and split in coil lead

[Markjh27]

Hey guys,
I ma new to this sort of thing. I have only just bought my seadoo jet ski.
It is a 2003 185hp supercharged gtx.
I took it out the first time only last week, and went really good, reved to 7+ grand. I took it out today and it reved to 6 grand on take off and struggled to pull really hard like it first did. I went to look at the plugs, and the leads, what attches to the plugs, one of them is split and has a crack down the sid eof it. Would that be causing my problem of losing revs and not as much power? It has only done 68 hours. And just had a major service done on it.
Any help would b greatly appreciated. THanks Mark

Welcome to the seadoo forum Mark. Depending on what you call a major service, it could be it needs to be fine tuned. I would replace the bad coil wire as that might be adding to the problem too... it definitely isn't helping it.
