SN#OG172120- Running the boat in about 4500 RPMs when the motor lost power, somewhat gradually. So I I mediately shut the motor down. Fast beeping alarm was sounding. Reset ignition, the motor started a couple times but would not run with any load, few more tries and motor will not start, and the beeping alarm sounding. It’s the same fast beeping pattern that if the killswitch is out or oil reservoir is very low.
i’ve ran some very basic tests so far. Oil reservoir full. Killswitch in place Compression is perfect 125psi x 6. Spark test revealed getting very little spark at all on some cylinders, after alarm sounds getting absolutely no spark on any cylinder. I’ve had the motor for a while and have repaired stater failures, switch boxes, and voltage regulators in the past. What confuses me is the alarm was never present during any of those failures. Any help would be greatly appreciated.
