I have a 06' 225 HPDI on a Ranger Z20. I have noticed twice that when my oil reservoir in the boat is same as dry the low oil alarm still has not went off. Is there a way of checking to see if it even works. Also if the boat reservoir goes dry is there a backup on the motor. If so if the motor reservoir is used some do you have to refill it or does it refill itself when you add oil to the boat.
I try to never run it that low but here lately I guess I've had my head up my arse.
