I have a 06 155hp sportster, had it winterized in Oct. went to pull it out with a fresh batt. no beeps & speedo & tach were erratic. Took it to the dealer who winterized it & after spending 4 billable hrs diagnosis they came to the conclusion the ECU in the dash is bad, this boat only has 34 hrs. on it. supposable the dealer is trying to get it under warranty but is not making any promises.? anybody know what would cause this with the low hrs. on it I think something is fishy
