The other day i was running my boat and it was running good for about half the trip until one time i slowed down and then sped back up and an alarm went off and it wouldnt go fast anymore. It would just bog down and i couldnt go more than idle speed. I checked over everything and the only thing that i thought could be the problem was it was low on oil. It wasnt completely out but it was pretty low. So the next day i put more oil in it and it ran fine. Does my motor do this to protect itself or was it even an oil problem? Maybe i dont have the problem fixed and it just didnt act up yesterday? I have an 03 60hp yamaha 2 stroke.
