I picked up my boat today after getting a new computer in it since the old one is apparently busted. It has a new battery in it. put it in the water, fired up the engines and took it for a run around the pond. after i make a lap around, the left engine starts to bog. i shut it off and now i cant get it started again. tried new plugs, didnt do anything. its getting gas, but no spark. I have no idea what to do or what the problem is the fuses on the panel inside the engine compartment are fine.
