    hard miss at wot

    hey guys when my 15 fz got a new motor it did the following (pre scom) 1 time at around 5 hrs- wot and bam a solid miss like i let off the throttle. now at 12 hrs and after scom it did it 3 more times only at wot. so i took it back to dock, pushed on scom wire and too the plug out of the fuel separator- there was a tiny bit of water on the end and idk if some water dumped out when i unscrewed it also the plug easily unscrewed and when i put it back in i got it tight. after doing the above it ran great. my rpms even pre- scom are close to 7700 what does the limiter feel like when u hit it? my plugs have 12hrs on them but man when u start my ski it is very rich!

    has anyone had this happen to them?

    More than likely you are hitting the revlimiter hard. Replace sparkplugs first to be sure you don't have a bad sparkplug then re test. If the problem is still there and your rpm's are 7700+ look into a larger pitch prop or reflashing your ecm to a higher rev limit. Tommy Jordan
