A friend and I went to help out a Haitian boat, stuck on a sand bar (Bahamas). After we towed them off, and showed them where they were (their distress
call noted that there were “several islands in sight”), the young boy (who spoke the only “SpEnglish” asked if we could look at their “possessed” engine
It seems that it would start “all by itself”, at unaccountable times.
After clearing a small space around the engine
(bags of rice packed against shipping
skids, laying against engine) , we noted that the bilge
was flooded up to just beneath the starter solenoid. Apparently, this was a “normal” condition of no concern.
What we also noted, was an old coffee can, floating in the bilgewater. As the boat rocked, the can drifted towards the engine, eventually landing against the solenoid, and shorting the start contacts. We removed the can - problem solved
Ergo - we be genius’ - they be so pleased & relived to have the engine exorcised of evil spirits.
