I purchased a pontoon last fall that has an old 2 stroke Johnson 25hp motor on it. Based on some googling, I believe it is a late 1970's, possibly a 1979? I can't find a serial number on it. I took it out a few days ago and it ran like a champ! But, I turned it off, attempted to restart it, and got nothing. No click, nothing.i swapped batteries and still got nothing. Floated on the lake for awhile, messing with the key and it eventually cranked enough to start. Got it home and it won't do anything again. I've replaced the starter switch and solenoid and it doesn't seem to have solved the problem. Im thinking I rewired the starter switch wrong. It has a solid red wire, a red wire with a purple stripe, a solid black wire, a black wire with a white stripe and a solid white wire. It's a 6 post starter switch that is identical to the old one. Someone please help!
