    Mid 60's 60HP Johnson just stopped

    I have a vintage 1963 16 ft Pipestone boat with a mid 60's johnson 4 cylinder 2 stroke outboard. I bought it last year and it's run great for 2 summers. Coming in from the lake the other day, it stalled and will not fire at all now. Has plenty of power to the starter. It just wont fire. I tried starting it this morning for a few minutes and same thing. It turns but wont fire. I pulled the plugs and they were bone dry.

    I am not a mechanic by any means and I dont know if what I checked means anything but here is what I did.

    I checked the fuel line from the tank to the motor and get plenty of gas going into the fuel pump. If I leave the fuel inlet hose on and remove the other 2 hoses from the pump and squeeze the primer bulb, gas comes out of one port but not the one that comes off of the diaphragm side. My guess was the fuel pump was shot so I removed it and took off the cover to the diaphragm. There was a short spring rolling around in there. I am assuming the fuel pump was bad. Am I on the right track! LOL I am going to need a fuel pump now any way because I have no idea how to put this one back together. I am just trying to figure out if it could be anything other than the fuel pump since there seems to be no gas getting to the cylinders.

    Any help would be appreciated

    A new pump may be a good idea, if not able to put back together, and it probably is quite old? If you have a timing light, clip onto each plug wire to see if all have spark (if the light flashes the same for each plug wire then you have spark.). Also take care of the pump.

    If not getting spark to plugs, you may need to pull the flywheel, or distributor(?) and inspect what's there? Mid 60's you might still have a distributor with points & condensers (not under flywheel)?

    Post back when able on what you find. Good luck.

      Thanks for the advice. It's gonna be a couple days before I can do anything with it. The boats sitting in the water and it's raining here in Northern Michigan for the next couple of days plus I just ordered a new pump online and it wont be here for a couple days. I will check the plugs for spark. That was one of my first thoughts as well but I just figured if they were that dry it must have been a fuel issue. I will let you know what happens

        I hear you on getting back to boat.

        This URL at the bottom is from the manufactures of Johnson and evinrude, well they bought OMC out. The new owners are: www.BRP.com

        I believe you can contact them directly if any questions on parts, for older motors.

          Thanks for the link. I think I will probably need it in the future.

          Finally got the fuel pump and installed it. Still wouldnt fire. so I pulled a plug and and engaged the starter. I saw plenty of spark and then got a big backfire. LOL scared the crap out of me. Luckily I didnt have my face over the cylinder. I put the plug back in and was going to give up but before I covered the boat I gave the key one more turn and it started right up. Took it out for a spin and it ran great.

          Could this have been some kind of compression issue? I really have no idea and am a little concerned that there may still be an issue and I am going to get stranded out on the lake. I am trying not to put a lot of money in this thing before the end of the season and will probably just leave it as it is and then take it in next spring and have it looked at. Probably only have a couple more weeks of the boating season left here anyway.

            Sometimes it takes a bit to get gas to flow, if the pump hasn't been working. For example, if the needle valve was stuck closed, then pump the bulb up, and maybe it took the fuel to loosen the needle valve, the pump pushed it open, and now the fuel is flowing. I would run it and see how it runs. If it's running fine, keep it running. Might do some good to run some fuel additive like sea foam. But try to run add much as able before season end.

            Good luck.post back if any thing happens.
