My boat has twin 305 Chevy OMC Engines. Now these babies been running and pushing my boat just fine.
The other day I was cruising at 2800 rpm - no issues ! I heard a loud click sound and the engine faltered , so I shout her down - limpeded back to port on one.
It wouldn't start up again - long and short - changed plugs- coil - ignitor electronic point module - filter and rebuilt carb.

It rolls over but will not ignite - I am running out of ideas - Help ?
