Hello, I did some searching but didn't see anything that helped.
A friend an I just purchased a 1992 Seaswirl with the 5.8L OMC Cobra Outdrive.
There were a few issues but we got them resolved and took the boat to the lake, it ran fine for the first two days but on the third, as we were pulling away, the engine just died. Nothing worked, no starter, no trim/tilt, no gauges… And the Tach was pegged at 6K plus…
Resetting the 50amp breakers got the trim/tilt back, replacing the ignition switch fuse got the engine to crank but it wouldn’t start. Pulled a plug and discovered no spark when cranking. After checking everything we could think of, we decide to unplug the ESA module, low and behold, we had spark and the engine ran but we had to shut it off to get out of gear (no shift interrupt).
We were able to use the boat for the rest of the trip but discovered a few more issues, if we just idled the engine and shut it off, it would restart just fine, if we ran it at high speed, we would have to reset the starboard 50amp breaker to get it to crank again. The Tach was still pegged at 6K and the only gauges that worked were the water temp and voltmeter which showed around 16 volts.
We ordered a new ESA, but I’m concerned that it is not the root problem, if anyone has any thoughts on what could cause this would be greatly appreciated.
