Well after 4 months of perfect running, my issue is back all be it with slightly different symptoms. Start my starboard motor, runs perfect. Simply turn the port motor key on (not crank motor) and the starboard motors stops. Start the port motor, runs perfect. Try and start the starboard motor and it just cranks and cranks, no start.
So I check for spark. What I find is that when the port key is turned on ( again not cranked), I loose spark to the starboard motor. Now just to complicate matters more, this only happens when the motors are hot. 3 times on the weekend the motors ran perfectly from cold start. Planed out without issue. Problem occurred when I brought boat off plane. Starboard motor splutters and dies, will not restart while port motor is running. Switch port motor off and starboard motor fires right up. This happens 3 times, so cannot be a coincidence.
This is doing my head in. I'm thinking my 1st fix it to swap out the coils as that is all I can think of that may be effected by heat. At least this is a fairly cheap starting place.
Any thoughts?
