I have a Searay 215 w/ Mercruiser 5.0
Was on water and shut off engine then tried to start and no electric power except radio. Jiggled every wire I could find and no resolve. Once under tow the engine started and ran fine. Also another time docked boat and shut down to rinse. Tried to start and nothing. The next morning dock crew started boat with no issues. I have checked all grounds and connections in engine compartment and behind dash. Checked battery connections and fuses I can find. It is very intermittent and sometimes seems to fix itself.
Any ideas?
