Hey all,
Took the boat out this memorial weekend, ran great for 3 days wakeboarding/surfing. Last day I was wakeboarding, and my buddy (a seasoned boat driver) stuffed by bow through a wake it happens wasn't that much water maybe 20 gallons. I hop back in the boat and go to run it home, get to about 2500-3000 RPM right before plain and it back fired/popped, I was real quick on getting the throttle back to idle and it idled fine. Tried again, same thing, I limped it back at about 10 mph no issues I was not able to determine if it was an exhaust pop or an intake pop just That the pop was definitely an air pop and not a mechanical bang. Had blackwidow (Jack and Cheryl) look at, couldn't notice anything other than my starboard exhaust riser was a little warmer then the port. Ran it at idle to 3000+ Rpm no issues while in neutral. I reached for my tools and noticed my negative terminal on battery 1 was very loose, and the positive connection on battery 2 almost completely came off. I tightened everything down, and we went out and tested it, no issues ran great. (However I was empty on ballast and just 3 people in the boat). Could the loose terminals cause a reset in the ECM/throttle position sensor/IAC valve? I am still not convinced and neither was anyone else that that batteries could cause this. Also ran the boat 6 miles loaded down going home the next day no issues any help would be great.
