Have Boat Questions? Ask a Boat Repair Expert.
Hello my name is ***** ***** I will assist you. Normally that alarm is due to either low battery voltage or low fuel pressure. If the engine is running properly and the you said the volt meter is pegging out then most probably it is either the alternator that is not charging properly or a loose connection in the battery cables. Start by checking the battery cables and if it persists you need to get the alternator checked out.
If you still require assistance let me know.
