I've been using my 60 EFI the last few days no issues, I shut of today and now when I
try to start I get 2 fast beeps followed by 5 slow. Anyone know what this means.
There was some water in my fuel. I'm using a fresh can and line I've drained that aluminum
can on the side of the motor. if this is (was) a water in the fuel issue is there anything else I can do to get the motor running myself????
 
Re: O5 Merc 60 Big Foot Buzzer Code

Looking through the guardian codes there is only one failure that would result in a total of 7 beeps on start-up.

A MAT sensor (manifold air temp sensor) failure will result in the inital "beep" on start-up followed by a total of 6 other beeps.

However, before starting to swap parts it really is best to get it into a dealer and have it hooked up to a DDT - the only real way to determine what the engine is trying to tell you...
