    Awesome motor! Fortunately, coils, points and impellers are still available at your local marine parts dealor. If not, you can find stuff here at iboats. If they don't have it, then try vintageoutboard.com, Seaway Marine, in Seattle, WA or Engine Blade and Prop in Milwaukie, WI.

      this motor has a different setup for the points i didnt see any rocker points all i see is the condensors, coils and the stands where the coils and condensor wires screw to. but no rockers points.

        Re: 1952 QD-13 Johnson 10hp

        Are you sure that it's a QD-13? I seem to recall that the ignition system was changed to the more modern rocker style points in 1951. At least they were on big twins and fast twins. You might look for a welch plug on the powerhead, the size of a quarter and see if the model and serial number on it, match that on the transome brackets. It's possible some one changed the powerhead to an older one. QD-12 and newer shows the later style point and coil set up, according to my Johnson manual. The QD-10 and 11 have a system that is similar, but the points set up have a push rod.

                The 1949-50 QD-10 & 11 have that goofy magneto with the obsolete 580040 coils, push rod points, and condensers that lay down. The "stands that the wires attach to" that you mention sound to me like the push rod points. They also have the goofy primer carburetor, no such thing as a kit for it.

                1952 has the familiar-to-everybody OMC Universal Magneto with rocker points and condensers that stand up. I'm reasonably sure the 1951 did too, but don't have the book on that one.

                  Re: 1952 QD-13 Johnson 10hp

                  Yep, QD-12 1951 was the first year of the universal ignition and I believe that the QD-10 of 1949 was the first OMC with the F-N-R shift and the Fastwin of 1950 was the second OMC product with it. As far as the carb kit, I would try Engine Blade and Prop. They have a pretty good NOS supply of parts for this motor and way earlier. I actually picked up a new set of rings for a 1937 Sportsman single from these folks.

                  As for your condensors, they lay down. The points on these set at .020. just like the modern ones. You may want to pull the push rods and clean them up and apply a fresh coat of grease on them, so they'll work free. These tend to get sticky, if the motor has sat for many years.

                  The design for the QD model was pretty much the same, from 1949 - 1952, with the exception of the ignition system. In 1953, the QD and the Super Fastwins were introduced with the Roto-grip handle. It was pretty cool lookin on a "fins forward" motor. 1954, the CD models and Fleetwins were introduced with the Roto-grip. Of course, the first OMC with the Roto-grip was introduced on the Big Twins and the RD's in 1951.

                    Re: 1952 QD-13 Johnson 10hp

                    I have a QD-11 that has the push rod points. The coils are fairly fragile and susceptible to failure I am told.

                    Most parts can be gotten for this old gem at vintageoutboard.com.

                    Sea-Way Marine still has points and gaskets too. But your points probably just need to be cleaned and they should be fine.

                      Re: 1952 QD-13 Johnson 10hp

                      I advise complete disassembly of the push rod points and thoughly clean all the grease and gunk out of them. Clean the contacts individually, then reassemble with just a hint of grease on the push rod. Excess only fouls things up again. Note that the flat end of the rod goes against the cam.

                      Do one set at a time so you have a sample of how the parts stack up when assembling, and don't lose any of the many little insulators and stuff.

                      If those 580040 coils are still good, consider yourself extremely lucky. Most of them melted down over fifty years ago and you will have to sell the farm to buy new ones now. Some guys have figured out a way to install other coils on the old laminations.

                        You could also change over the an armeture plate assembly from the next model year too. I still believe your powerhead is a '49 or a '50.

                          hi guys

                          i uploaded a pic of what the points look like.

                          after putting back together is it the same theory to set them. make sure im on the high then set with the feeler gauge at .020.

                          the coils are in very good shape and there are not cracked they look new. the motor has 90pounds of compression on both clylinders and getting spark on top clylinder but not the buttom. customer told me it was running last spring.

                          anybody know where i can get a shop manual for this motor.

                          i have a cymer shop manaul but it covers 1956-1972 1.25-125hp.

                          thanks jeremy

                            Huh. The coils do look in good shape! I'd work on cleaning up the points to try and get the other spark. And as mentioned, maybe see if you can convert a modern mag plate over... that'd make it easy for parts in the future...
