It was late in the year and on both deliveries we got into rough weather and both engines stopped running. The second delivery was a 40' Hunter. Something about how the boats bounced in the large swells just screwed up the engine.
Pretty typical. Any crap in the fuel tank will make itself known when things start rocking and rolling, it gets stirred up, plugs the fuel filter and kills the engine.
I'm a strong believer in fitting dual oversized canister primary filters with isolation valves (and transparent sediment bowls so you can see what's going on). Run on one canister with the second isolated in reserve for that dark and stormy night when the engine starts coughing. Not that I have ever been caught dead in the water on a lee shore or anything...
