I have a pair of 2001 150hp optimax. Last time I used the boat the engines were running fine, but on my way back the boat started beeping four times every 2 minutes. The was no loss of power or hesitation or anything, boat ran perfect back to shore, just beeping every two minutes. While I was at home flushing the engines, I realized that the beeps will go on only when i turned one of the engines. So the error is coming from the startboard engine only. I have searched the forum for my problem and so far I've read that it could be low oil or water in the fuel. So far I refilled both my oil tanks, they were a little low, but not empty. They are full now as well as the reserve tank in the engine. It still beeps. I unscrew my fuel filter on the engine, didn't seem like it had any water in it, but still replaced with a new filter. My beep is still on. Im not very good at troubleshooting so I don't know where to turn next. Any help will be appreciated. Tx.
