Hi Guys
I have in the passed discussed this issue but have been unable to solve it, so my questions are will this do dammage to the motor, and can anyone think of another solution.
I have a 1999 Sea Ray 180 with a 135 hp 3lt Mercruiser and Alpha 1 leg. The motor frequently runs on after the ignition has been turned off, some times for over a minute, even after allowing it to idle for a minute or two.
I have had it serviced, and lowered the idle speed to just above stalling, which it now does painfully often and does not idle properly when cold.
I have used hotter and colder spark plugs ( now using Irridum tipped), better but not stopped.
I have used a fuel system cleaner which is also supposed to remove carbon deposits.
I have tried different fuel grades, changed the air filter ( K&N), fuel filter ( Merc)....
and I have danced around the boat in small circles ( after I burned my hand)
And still I cannot stop the motor running on.
This is especialy irritating when out sking as I do not feel it is safe to clime aboard untill the motor stops.
So will it dammage the motor or should I continue to look for a solution???
Cheers
Mark
