Hello, I have a 1995 Evinrude intruder (E150GLEOM) that runs great, till it doesn’t, I have a very inconsistent no spark if I want to go fishing at 6am on a cooler/damp morning she will not start no spark I trouble shoot everything with my oem manual but find nothing to be the culprit, if I get mad and drive home and try to start it she will 9/10 fire up and never miss a beat the rest of the day. Maybe I just have the only boat that doesn’t like to get wet,
This is my first boat bought back in June 2019 found out that the owner has been dealing with this issue for the past 3 years, now a little back story and repairs that have been done. Hunting down the issue
the boat wiring has been redone all new ignition, switches new wires from the battery’s and engine back, I had to install a starter from it seizing up (thought i finally found the issue from it dragging. but it randomly appeared back 2 weeks later with no spark) I’m running the correct plugs/wires my battery’s are a few years old but still show good on a tester but I am planning on changing things out this spring, I thought I found it one time i was going through the trouble shooting and unplugged the port side square connector on the power pack (kill side) and the thing fired up plugged it back it to kill the engine, went to start it again with the plug still attached and it started up and never messed up again till a few weeks later when I wanted to fish in the morning, tried to do the same thing again but it never started after I unplugged the port side connector, so back to square one again. I feel like I’m missing something very simple, how can I have the only boat that doesn’t like to be wet from the morning but can fish on Lake Erie in a crazy storm and fire every time. Could I have a power pack, stator or rectifier failing? I noticed last night after cleaning the boat out getting ready for this year that the rectifier has a little blackish/orangish ooz down the side of the block, I thought was just someone got messy with some sealant but I don’t think that is the case anymore
i tried to think of everything hopefully I didn’t miss anything and thanks in advance
