This might belong in stupid human tricks but my boat would not start after 3 weeks of being idle. The relay clicked like a bad battery so I charged it. No luck. I always laughed at the emergency rope inside the hood of my 115 Mariner 4 cyl. As if anyone could pull start this thing cold I thought. Anyway, it was either try pulling or paddle a kilometer to the ramp.<br /><br />After about 10 brutally slow pulls, it coughed and spun a bit. I couldn't believe it. Primed it again, added more throttle and it started! Let it warm up, backed out and it died. Pull started it again. Yelled to the wife to meet me at the ramp since I didn't dare stop it. So with no hood I took off. Part way there the engine started running rough, I lost power trim control, but I made it. Only now I would have to climb in to some really cold water to open the trim's bypass to haul up the motor. I smacked the motor in disgust and suddenly the trim worked. Raised the motor, set the lock bracket, and it was dead again. Talk about luck.<br /><br />So what caused all this? A crappy ground connection at the battery. Apparently I was too smart to check the basics before diving into the details.<br /><br />So, what's the biggest motor anyone has ever pull started?
