    Need Advice on a Evinrude 15

    The problem with listing a motor that does not run is the uncertainty alone forces a very low price. If you can get it running you can either use it or get fair market value but as a non-running motor you would need to discount it about 80% or more to get a knowledgable buyer and...

    1963 Evinrude won’t start

    I built this one from Leeroy's Ramblings and it works great. A piece of wood cut with a jig saw and two bolts with nuts to allow adjustment. Spark plug boots go on the bolts and you attach the clip that's connected to a metal plate at the top of it, to the motors ground and pull the starter...

    Vintage 9.5: Can you set points with a timing light?

    I have used the multimeter method of determining proper timing, many times, where I find the exact moment the point opens, and then align the flywheel and confirm the timing marks are good. When I am done I will also check the point gap. In every single instance the point gap was at the 0.020"...

    1975 9.9 sea horse

    Looks good. Nice water flow from the water pump. A good carb clean should deal with that choke requirement.

    1975 9.9 sea horse

    You really should get a carb kit and replace the needle bearing inside the slow speed jet and the carb to intake manifold gasket. You will need a new welsh plug if you want to clean under it and since your problem is almost certainly the carb, and more specifically right in that slow speed jet...

    1975 9.9 sea horse

    Not sure what that means. OK. Your coil clips are fine. Since we know the fuel is getting to the end of the fuel line coming from the fuel pump but not to the cylinders to maintain operation, you have to have a problem between the carb and the cylinders. Time to clean that carb again...

    1975 9.9 sea horse

    The best spark plugs for that motor are NGK B7HS. That said, spark plug are not your problem. So you have confirmed spark and you have good compression. You said you confirmed that the clips coming from the flywheel and going to the coils cannot be switched. I was under the impression they...

    1975 9.9 sea horse

    Here is a homemade spark tester that I got from Leeroy's ramblings that is made out of a piece of wood and 4 nuts with 2 bolts, with a metal plate for the ground wire. I made one identical and it works great. You can see both sparks alternating at the same time. Black tape at the back helps...

    1975 9.9 sea horse

    If the wires from the flywheel to the coils are switched, where coil for cylinder #1 is actually going to cylinder #2 and vise-versa, your spark would be firing at precisely the wrong time, at bottom dead center on both cylinders. You would get almost nothing from the engine in that condition...

    1975 9.9 sea horse

    This is probably not your problem, since I don't think the link and sync could be off so much that the motor would not even pop with gas added to the cylinders, but when you advance the throttle you will notice that the armature plate will rotate and the armature's throttle cam will start...

    1975 9.9 sea horse

    The points set at 0.02" is enough. The timing marks are to be lined up not when the points are opened to 0.02" but line up when the points just open. You would need a multi-meter to identify that moment and then line the flywheel up with the key and see if the timing marks line up then. As...

    1986 Evinrude water pump issue

    One last question in line with my others. I have never drill tested a water pump. I just install them and so far not had the kind of problems you are seeing. With drill testing I assume that you assemble the water pump. Submerge the lower unit into water, the level of which is well above...

    1986 Evinrude water pump issue

    This things seems to be defying the laws of physics and we know those are laws that don't like getting defied. This is probably a really dumb question, especially since I think you said you have already changed pump housing components but is the little hole that goes from the impeller housing...

    1986 Evinrude water pump issue

    Yes. Quite a mystery. Have you tried putting the impeller on the drive shaft with the impeller key in place, without the housing/cup, and visually watch it turn on the drive shaft? If it does, put a little finger resistance on the impeller fins and see if it still turns on the shaft. After...

    How to get my throttle roller closer to the armature/flywheel?

    Also, I think your motor is missing a piece on that carb roller. There is usually a clear plastic piece that actually touches the throttle cam. You may find it hard to sync it up properly the way it is. The best fix is to buy the proper replacement roller but I found a piece of 1/2" pex pipe...

    1992 evinrude 15hp weird symptoms

    Perhaps it is the fuel line. I had one that always worked perfectly in the mornings, with cool weather, but after a while with the warm sun it failed. I suspect the check valves in the primer somehow would get stuck. Priming the bulb worked OK but it would not move fuel automatically. I say...

    Johnson 9.9HP Throttle Setting

    A little more info so you understand what is going on here a little better. The main reason you want to sync the carb with the throttle cam is not just to ensure you get enough fuel to start your motor, but to optimize the spark timing with the various RPMs the motor will operate at. So you may...

    Johnson 9.9HP Throttle Setting

    So yes. The motor gets fuel even when the cam is not touching the roller. In other words when the throttle butterfly is completely closed, some fuel still flows to the engine. That said, the question remains if it is getting enough for starting. I should have added to my post that even...

    Johnson 9.9HP Throttle Setting

    You need to make sure your link and sync are set up properly. Not sure precisely on your motor but you will see that as you advance the throttle a throttle cam (metal piece) moves counter clockwise and pushes on the carb roller to provide more fuel. There should be a mark on your throttle...

    Checking Pts without Removing Flywheel CD-18

    So I am planning on changing the impeller on my 1961 5.5Hp Johnson and decided to remove the starter before I remove the powerhead. Once off I remove the little cover for the hole that allows you to check the points on this motor without removing the flywheel. I was wondering if anyone knew...
