I will be taking her fishing this weekend. Iran the motor for several minutes...

    1973 18 hp evinrude Driver Coil test

    Yeah I was thinking about the rebuild kit over the new one, I took this one apart once already and inspected the Diaphram and check valves and they looked like they were in good shape, buy never hurts to throw a 6 dollar Diaphram in just to be sure. I love the advice!!

    Like one of these, if its clearance issue, I can just swap the base of the current one of the engine.

    Would this fix a qeak pump? Or would I need to get a new pump?

    And I'm sure rebuild kit is cheaper then new pump, do you think rebuild would be sufficient?

    @racerone , with cowling off it was similar, here is a video where I take it off, you can see the exhaust here as well, it was blowing away towards the garage. I do not have a fan blowing exhaust away, I did a decarb on it. The spot I was tho on that wall its like a wind catch, so wind was going...

    20 hp Mariner No spark

    So I tested and it was missing, inspected the coils and when running the top spark plug wire was shocking me but not the bottom. I ordered new coils. They will be here Monday. I took the boot off the back of the coil and this is what I found. Broken pieces, would this cause a miss?

    I did have 2 x 4s under the tote...lol that's what broke it. Well I swapped to the old condensers and that miss is not there. I got champion J4C in. Not sure why the condenser did that either, I know when I test it, the readings go up faster then the others, and to be clear it was only the one...

    20 hp Mariner No spark

    Got the carb out and took it apart, Diaphram had holes and all the gaskets were crusty. Would this cause rough idle? Gonna clean put all new gaskets in and spark plugs then test, then to the lower end.

    Swapped old condensers in and tuned points with a multimeter, checked gap at the set mark on cam, was sitting perfectly at .20 and look at her run. The new condensers in the tune up kit lasted 5 trips, think these old ones are as old as me....lol they sure don't make things the same any more...

    20 hp Mariner No spark

    Is 16 the main jet? I am gonna do a rebuilt kit on this carb when I get more time but for now I will take her easy on it. How about spraying some seafoam in the carb? Think that will clean it out? 🤔

    1973 18 hp evinrude Driver Coil test

    So this is with the old points in and 1 old condenser in, I am going to order some OEM points and condensers. That aftermarket stuff is not the best. Still needs some fine tuning but it's a lot better. I am going to set the points with the multimeter and test again.

    20 hp Mariner No spark

    Well, did an adjustment on the carb needle and the engine ran good. It will need a carb rebuild, it is leaking a little from some areas, I will tighten the screws and bolts to see if that does the trick. But before that think I am gonna take it for a spin. How does it sound, I would like a...

    1973 18 hp evinrude Driver Coil test

    Yeah this cam has a set point stamped into it. Anyways got a good update, I reviewed what I did and realized I swapped the condensers. The problem followed the condenser. Did not realize until I reviewed my procedures I have done today. I put a old one on. And tried again and it ran better, with...

    1973 18 hp evinrude Driver Coil test

    So I swapped out the points with the old ones and re gapped according to leeroys rambling and with a multimeter. Same issue, intermittently sparking on the bottom now. I adjusted the driver coil air gap best I could with the eyeball. At a loss. I ordered a new driver coil for giggles, got a...
