Hi all. I am unable to start, or at least keep running, the engine on my boat. All fine one day; then, after fiddling with the non-working radar interface, the engine now won't start. The Mercury Smartcraft dials also lack power although other ancilliary equipment is fine, so no problems with the batteries. Note that if I turn and hold the key at the 'start' position (against the spring) and at the same time push and hold the additional (separate) start/stop button on the throttle lever housing (i.e. two simultaneous methods of starting), the engine will start and the Smartcraft dials work. But as soon as either the key or the button is released the engine stops. Normally, the engine starts and runs by using either the key as usual, or by turning key just to the on position and then pushing the above-mentioned start/stop button on the throttle lever housing. I have checked every fuse I can find including the two located in the engine control module housing. I can find no loose wiring at the helm. Interestingly, when the key switch is operated the trim tabs reset themselves as usual. Any ideas what I should be looking for or doing? Thanks.
