Check engine light stays on

My 2005 Sportster 215 runs excellent, no problems starting, idling or high speed but the "check engine" light goes on immediately when the plunger touches the starter hub. A local jet boat repair guy claims it is my ECU but I don't want to drop a grand to just get a light to turn off. It would be a different story if the boat wasn't running so well. I had the oil changed and new plugs, but the light stays on.

Just like a new car your boat has a computer that stores trouble codes. Without actually reading the codes the "local repair guy" and us here would just be guessing.

Thanks, I was hoping someone had a similar problem and I could try a few less expensive "guesses".
