Ok so first I’d like to express how priceless this wealth of information is on this forum.
I have an 87’ merc 165 3.7l 4 cyl. that I converted to electronic ignition midway though last boating season (July 2018). The boat ran great for a few weeks, one of the weeks seeing daily use, as I was on vacation in the st. Lawrence river with the boat. The boat then sat for about a week, ran it for about an hour, stopped to fuel up, left the dock and as I was getting up on plane the boat cut right off and died. Would not start at all. It was late so I did not have time to trouble shoot at the time. Long story short I pulled and winterized and decided I would get it going this spring.
Well this spring, after determining I wasn’t getting any spark, I changed the plugs, wires, cap, rotor and cleaned all terminals and wires on the coil. It fired right up. Also I cleaned fuel filter before carb inlet and on fuel pump. And I am in fact getting gas in the carb when I pump the throttle. (Carb is good....I think) I rebuilt it winter of 18 and ran it for months before converting the ignition. Now it seems to idle fine when not under load. Haven’t water tested yet. I’m worried it will do the same thing and leave me stranded so I’m brainstorming what went wrong last summer, as I don’t believe bad plugs or wires would have cut the engine right out like that. I was
Externally resisted coil was new when I bought the pertronix ignitor 1 last summer. I notice while idling that the purple resistor wire from the choke is getting quite warm. Is it normal for this wire to heat up? What sort of thing could have cause the engine to abruptly cut right out?
I understand this topic has been discussed before, I’ve read for hours on this very topic and still haven’t came up with any answers I feel comfortable with. Any help is greatly appreciated.
