1998 SN GT40 engine ecm


Recommended Posts

Thanks guys. took one of the old bad ecms off the shelf and inspected the capacitors on the motherboard out of curiosity. Found both to be bulging. I believe the heat may have caused a hydrogen gas expansion in the capacitors. This ecm has nichicon capacitors which were known to be faulty. I have had many Ford Trucks and Mustangs with somewhat similar ecm with never a problem. Just my bad luck. However, my boat runs 3 to 6 times a day in the summers. No idea what my hours are since the hour meter went out when it was fairly new. I replaced many a capacitor on IBM computers when I worked there. Will let all know how the capacitor replacement goes.
