Error Code -- 2012 Super Air Nautique 210 - need h

Most of the guys here have older boats, so while I am hoping someone can help solve your issue, there may not be much of an experience base with this question here.    I would suggest that if your dealer just did a bunch of work on the boat, you may want to at least include them in the troubleshooting process.   I don't take my boat anywhere for service, but have had similar experiences with car shops.   a mistake in hooking something up, or failure to reset things properly can happen and may be a warranty issue for the repair you just had.    It is possible that something else went wrong, but it would be good to at least check with them to see if they would weigh in as they just performed major work for you.   Not including them in the repair or questions would definitely give them reason to say that you had broken it after their repairs were complete.
