hello I had posted a while back about this motor as no spark on any cly. someone had told me they was voltage sensitive I had a new battery but I piggy back another in series and had spark on one bottom cly.. Put battery charge on it at 60 amps around 15 volts got fire on two bottom clys.. This with the plugs out haven't tried it with plugs in. I need to sell the boat I had a stroke five years ago and want be getting back out on the water nobody wants a boat that won't crank thanks for any help you can give me
