A few months ago my family purchased a seado sportster 4tec 2004 but they never they just dident sell them. We were out on the lake (georgian bay) and this anooying beeping sound started we though was one of the warning lights but none were lite up so we dis regarded it. There was this loud constant high pitched humming. The next day we took it in to the marina and they plugged it up to the computer and there was nothing visibly wrong with it. They ran the engine and everything. In the end they just said they would order us a new brain. has this ever happen before. I might have been that were were out in 10 foot waves but i dont think that would make a difference. Our fish finder tranducer was totaly bent up from the waves. I'm just wwondering why this would have happened.
