Serviced my boat early May ran the motor '85 Evinrude E90TLCOS and cleaned things up after winters storage. Motor fired up and ran good. All was good for my first outing. Finally had the opportunity and pleasant conditions to put the boat in the water. At the ramp the motor wouldn't start. Cranked strong, primer pump was delivering fuel, but never even sputtered. Pulled it out and came home.
At home I pulled the plugs and they were wet. (new last fall) Using a spark tester I had made in prior years no spark was seen jumping the 7/16" gap on any of the 4 high tension leads. So, I doubt it would be all 4 of the coils at once and unlikely that both power packs went out at the same time in a 3 month span so I'm in the fog as to where I should look next? Could it be the rectifier / regulator? I've gone over the wiring looking for any evidence a rodent may have chewed something but didn't find any such evidence and all connections seemed secure.
In the fall of 2018, I had conducted a spark and compression test. Spark was strong in all 4 high tension leads. Compression on the cold engine was 110 / 109 / 108 / 108. Fuel tank was full over the winter and there is a water separator in the system.
Any suggestions as to where I should look next would be appreciated.
