Engine shuts down into safety mode? for no apparent reason. Switch off and restart and all is fine! Had computer analysis done and no problems show. Any ideas?
Long shot this one based on recent experience. Ive got a 2002 60 efi which recently behaved similarly. Turned out to be a blown regulator/ rectifier which is a known fault on 40 50 and 60's. Ran, stopped, ran, stopped.
Telltale apart from not charging was scorch marks on the inside of the cowling
Yes its a 40efi. No alarms sounding, no faults logged for the computer to identify. I'll check out the regulator/rectifier. Happened again this evening after it had been idling for a while.
Thanks for your input.
it will only go into guardian for either a oil fault (oil pressure switch?) or an overheat first check the thermostate or worse case senario the grommet between the leg and the adapterplate.

Thanks for that information. Replacement of the thermostat was the first fix tried, and I am beyond "the worst case scenario" as it is now two weeks since a strip down to check the grommet (which was fine, but was replaced anyway). Haven't had a chance yet to check out Portholme's suggestion of the regulator. The fault goes on and the frustration increases!!!
there was a service bulletin out on some voltage regulaters on some of the 40/50/60 hp efi, when i was working (retired now just under a year)i dont know if yours was done/or needed to be done at the time,it might even be out of the period for a warranty repair within the service bulletin time it might be worth checking,you will require your serial number.
