As the topic stated, my 59 evinrude lark, just blew both condensers.
Intro... motor has been a work in progress, with little to no power most of the time. After replacing coils, condensers, points, wires, plugs, and apparently a cruddy job rebuilding my carb and fuel pump, I was able to get it running well enough to idle and run, but still had no power.
I was about to give up, so I took it to a local shop, who did another carb rebuild, fixed fuel leaks at the idle and high speed needles, and told me I had lots of water in my fuel. So, flushed the tank, filled it with clean fuel and oil, and installed a fuel water seperator between the tank and the motor.
Testing time... Ran beautiful in a test tank. YAY!!!
Out to the river... Started first push of the button YAY!!! We rev it through full cycle in neutral, sounds fantastic. Ready to go for a ride.
Head out, giving 1/4 throttle, and it's already running better than ever. Goose to full throttle after exiting the no wake zone, and she's up on plane within a second or two!!! YAY, holy cow, this motor can push HARD!!!
So I'm grinning like a fool, flying up the river with my wife and daughter, all of us smiling from ear to ear. Fantastic.
Then... make a turn, and she stumbles. I see a little air in the fuel water seperator, so I tell my wife to hit the bulb a few times.
Temporarily fixes it. We keep cruising.
Next turn, she stalls out completely. This time I pull the cover off the outboard. I can see a little air in the fuel water seperator, and a little in the cinnamon bulb.
Not great. So I pump the bulb, and I'm getting fuel on my hand at the bulb. Ok... I've got a fuel leak, air's getting in the line, I know what happens with a straw with a hole in it, so I'm not too worried. I can fix that later. Pump the bulb, and try to start her, and not much is happening.
Finally get her to fire, head back to the dock, and it quits completely. This time she's smoking. Head is really hot. Crap... did the water pump fail?
So, It's time to head home. I give up for the day.
Get her home, take off the bottom end, and check the impeller, good to go, no problems. Take off the thermostat, and try to crank her in a barrel. Still not cranking, but even with that, the spinning of the starter, should have pushed some water up to the thermostat hole right? Maybe? I'm not sure.
Take off bottom end again, and run water down the thermostat hole to see if there might be a blockage. Water comes out one of the two pipes, and out of one of the exhaust tube. Not sure if that's normal, but that's what I got, so I put things back together. Hoping for info on that from yall!!!??!?!?
Then, I check for spark. Not getting anything. Crap. How'd that happen? It was running beautiful, for weeks, and now it even had tons of power, and now I have no spark. Wierd.
So... I pulled the flywheel off, to inspect, expecting a coil to be bad. But instead I find both condensers, completely melted and the tops are broken off. No condenser, no spark. Ok I get it.
But what could have caused that? These were run maybe 45 minutes tops.
