The motor:
1977 Mercury 115 Tower of Power
I was at the lake, all was well until......... the starter solenoid seemed to crap out while on the water around midnight after a night of fishing. The solenoid would just click rapidly so we knew it was toast. In desperation I jumped across the solenoid with a screw driver which started the boat just fine so we continued to the dock with no issues. We went to put the boat on the trailer and had to restart the motor jumping across the solenoid again only this time the motor would turn over but didn't want to continue firing once it got it's initial fire. We used the trolling motor to get the boat to the trailer and got it home where I just replaced that solenoid. Unfortunately it still won't start, just like it did at the dock. It turns over good on the new solenoid and starts to fire but then it dies. I've pulled all the plugs and cleaned them all and I've got good spark to each plug. Could I have blown something in the jumping of the solenoid?
I'm at a loss where to go from here. It's getting fuel and spark..... it's acting like it's shorting out and killing itself the moment it starts to run. I've got a Seloc manual for it but I just don't know what to check next. Any help is much appreciated!
