Hi Folks,
Thought I'd report back on my results.....
I never got to check for 'spark'...nobody around to assist.....
Anyway, I decided to take Woodsy's last suggestions....
I noticed the iginition swich was sticking when I turned the key, so I sprayed a little WD40 on key an into switch.
I then disconnected the 3 wires that connect to the back of the switch. I suspect one is POS the other Ground, not sure about the third but looks like it goes to the alarm control (Mercruiser). Cleaned off terminals then put wire connections back on.
Checked the 'Lanyard' swithc, moved up and down a few times, seemed OK.
Then 'wiggled' throttle handle to make sure it was in neutral.
I then cranked engine over, and VRRRRRRRRRRRROM engine started,
I ran it for a few minutes, then shut off. I then started again without any issues.
Know I don't know what the actual problem might have been ? Could have been sticking ignition switch on dash? Could have been 'Lanyard' switch not closing properly, or could have been throttle not exactly in in neutral ?
Could have been Sun Spot flareups for all I know !
I guess the expression 'KISS' applies here, think basics. Lessons learned !
Anyway, problem solved. Whew ! Going to winterize and put boat to bed for the winter this weekend.
Can't thank everyone enough for all their input, much appreciated !
