Hey I have a 2003 efi saltwater series motor I am having a couple of problems the fiest problem is that it seems to be having is with the oil tank on the motor I have a mercury scan tool and it keeps reading that the oil tank is low.I purchased a sealoc manual followed their diagnostic tree and sure enough it pointed to the tank level sensor replaced still have same problem the tank is full and staying full
the motor is getting oil it does smoke slightly at start up . I am getting a 3 beep signal wich nobody seem to be able to explain what that is then next it gives us a four beep tone then when we have had the boat we got a steady tone we idle it back that goes away but the three tone and four beep tone still constantly keep re accuring it has never to date triggered the guardian but motor seems choppy and low on power compression is well within its spec according to sealoc water psi seems to be in spec. any help would be appreciated
