Signs of SC failure???

[rxtshea]

Hey, was out on my sea doo today rxt 215 2005 has 79 hours on it and it started to bog off the get get but once plained out or give it some shots of gas it runs perfect and still got 69mph out of it. It only did it couple times then stopped then later on again taking off did the same thing. I was thinking it was the plugs so I changed them out they did need to be changed by the looks of them hoping that was the problem and not my SC starting to fail. Any info from others with this problem would be great

Sounds like plugs to me.
