Finished up my 400hr service and put a new prop on that I wanted to test out. I left the house with the cowlings off because this weekend I was going to tear into the intake and check the reeds per the service manual. I know.....dumb thing to do.....go run the engine without the cowlings where water can get inside and potentially cause a catastrophe. I was only intending to run up the lake a short distance and back down and head home. Boat ran fabulous! On the way in I decided to check out a small cove and make a few casts before putting it on the trailer. I came in a little hot and upon shutting down some water rushed up and came across the engine. Not enough to run up inside the plenum, but enough the electrical got wet. I shut engine down and fished for a few minutes. When I went to start it, I ran about 2 seconds and shut off. It would turn over fine so I figured I pulled my kill switch. Nope......so I started checking fuses. I found a 20 amp fuse (#4) in the main harness popped. I replaced it and it started and ran about 2 seconds and shut off again. Today I unplugged most every connection and sprayed them out with an air hose and reassembled. Upon replacing the fuse again, when I turn the key on, it still pops the fuse.
Any idea where to start looking?
Obviously I won't be making that bonehead decision again to run without cowlings.
Thanks
EDIT....so I went out and did some testing. I unplugged every coil and 1 by 1 plugged them in and then hit the key starting from the bottom. I got to the second to last one (#1) and it popped. So I replaced the fuse and unplugged it and tested the last coil and it did not pop. So now I decided to move the bad coil to isolate if it was the coil or the wiring leading up to it. I swapped #1 for #2 and plugged everything in.......The damn thing didn't pop. The engine starts and runs. So now my question is.....if a coil is going out, will it be intermittent? I'd hate to replace it and it not be the issue. Thoughts?
