    You have to change the oil tank on the engine. The float inside is heavy with oil and is no longer floating.

    Hi and thank you for the answer. I wonder if it's possible only to change the float in the tank or is that difficult to do? Is it posibol for me to drive the boat if I dont drive over RPM 4000 or is that no good for engine? Will the engine receive oil anyway or not?
    Thanks in advance for your help

    Hi Again.
    I have try know to change the oil tank but stil have the same problem. When the problem was coming up after the oil sensor have been change I take Master reset on the Smart Craft system but I have not taken calibration on the system,can that bee the reason that I have the same problem?
    Sombody say that it can bee that the oil pump is broken, but I dont know becous I think if the oil pump is broken the alarm will run when you start the engine not like it is today that the alarm go when I come to RPM 4000 and go in to
    Safe mod.
    I dont know what to do and hope you can help me litel
    Thanks in advance for your help
