I have a 1993 15 H.P. 2 stroke Evinrude. I run this thing all the time on the dinghy for my sailboat. About 2 (now 6) weeks ago I hit a clump of seaweed and it nearly instantly overheated and I manually shut it down quickly.
Then it would not restart. I noticed I had burnt out the ground wire on the power pack and replaced it. Then the engine worked again but gradually, over a few days, started taking more and more pulls to get started.
Eventually it would not start at all.
I was getting spark on both plugs but it was VERY WEAK. With my DVA meter I read only 2 Volts on either orange wire leaving the power pack and heading to the ignition coil.
I then replaced everything electrical on the motor - I replaced the plugs, the plug wires, the power pack, the ignition coil, and everything under the flywheel. I rewired all the grounds. I even added new wires to ground the grounds together to make sure everything was well grounded. I left the kill switch out of the loop.
I get good voltage now going into the ignition coil and when I pull the plugs out and look at them, I can see spark. It still looks like a weak spark. Either way, when I put the plugs back in and crank the engine I still get nothing. All the electrical is checking out according to the manual I have and testing with a DVA meter and Ohm meter.
I've opened the carb and sprayed starter fluid into it - nothing. I've removed the plugs and spray gas straight in there, closed it back up, and tried and nothing.
I've checked compression on both cylinders and its about 85psi, which is what it has always been.
I've disconnected the kill cord to take it out of the loop.
I'm at a loss. All my mechanic friends are out of options. I'm hoping the internet world may have a suggestion before I turn it into an anchor.
Thanks for any tips!!
