Yes, Several Times
The first time was when anchored in Quartermaster Harbor, Vashon Island, Puget Sound. After a wonderful night at anchor we decided to leave around 10 am. The wind was blowing 20 kts and I went to start the motor before weighing anchor. gRR, gRR... Had to get the sails ready, weigh anchor, set sail, and sailed over to Quartermaster Yacht Club, sailing through a bunch of anchored boats and dock on the outside, a 35 footer on about 20 feet of dock space. Had one chance and my significant other was to quickly jump off the boat with the dockline and get it on a cleat but panicked at the last second so I quickly took the line and jumped off and cleated it, and ditto with the other lines. Asked the neighbor if I could borrow a few amps to run the 4 amp charger I had and about 10 minutes later there was enough power to crank the engine and it started. We sailed out on a broad reach and the engine at fast idle to charge the battery and made it home fine.The other memorable time was in Pender Harbor up the "Sunshine Coast" in BC on a cold, wet, and windy morning. This time it wouldn't start so I opened a couple pressure release levers and after a bit water was running out of the air cleaner. This took a mechanic and several hours to figure out the problem.
