The kids are scared to get towed behind the 22', so I have one of those horrid 13' jet boats w/ the 90 hp merc sport jet.

Today it started running on 2 of three cylinders for a few minutes. I pulled the plugs, bottom one all wet, cleaned and put back in. Still two, then none. Must be electrical. I have heard somewhere that these have a common electrical problem. Anybody know what to do?

Thanks
