Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís thread (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new thread of your own.

4. If you have a question for the original poster (OP) and the thread is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old thread.

5. By starting your own thread, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

  • 1958 Johnson 10 hp. coil question

    Which coil serves which cylinder? I don't have spark on the bottom cylinder and can't tell which is which.

    The front coil, the one over the carb is for the top cylinder. The rear/aft coil feeds the bottom cylinder.

              Awesome motor you got there Earl. It's a 1958 Johnson, QD-19, 10 hp. One of the all time great motors and super cool looking. I used to ahve a '61 QD-22 myself. Here are some great links that will help you get/keep it running for another 50+ years. You can get any routine parts you may need right here at iboats.

                Step 1 is to check compression on any new motor to you. It serves not only to determine the health of the motor in its current state, but to also give you a baseline for future issues.

                Step 2 pull the flywheel. Have the coils and condensors been changed>? If no, change them. If yes, dress the points by running some emory cloth through them, then clean with acetone and run some business card stock or clean paper through to ensure there is no oil or grit left on the contact areas. That should get the spark back. Also want to ensure the wires have good continuity to the plug boots. If you are changing the coils, change the plug wire at the same time. You want to use metallic core 7mm wire. Plugs are Champion J6C.

                Im not sure how far you have gotten with this motor, but also ensure the fuel lines have been changed with new ethanol proof lines and clean/rebuild the carb. You dont want the old lines gumming up your newly cleaned carbs. I would also drop the gearcase, change the impeller and regrease the splines on the drive shaft and change the o ring. Finally change the gear oil along with new crush washers. If the oil is milky, may be time for a reseal.

                Now go through the motor and clean it up, after wiping down with WD40. Regrease and oil where needed.

                These are the basics I do on any of the 50s OMCS I aquire. It ensures the motor runs trouble free and lasts another 60 years.

                  Re: 1958 Johnson 10 hp. coil question

                  Thank you everyone for all the advise. So far I've replaced the recoil spring on the pull start..... That was so much fun I invented a 23 syllable cuss word while doing it. ( who knew a spring could fly THAT far) The coils have been replaced but the points for the bottom cylinder are burnt and pitted. It's been stored in a garage under cover for the past 34 years and is really clean. The guy I bought it from didn't know how to fix the starter spring and just put it away. I'm pretty excited. I've got a 60's ( I think ) 12' Mirror Craft V- bottom to put it on. C'mon spring!

                    Awesome. Should look nice.

                    THe springs are extremely dangerous. No one that has done it will think you look silly wearing safety glasses when doing it. I always put them on, just in case.

                      Well, if you can replace the starter spring, the rest will be a breeze! I've had people wanting me to replace that spring, and I've gotten to the point where I just recommend they let me find them a replacement recoil assembly.

                        For Future Reference:

                        (Manual Starter Assembly)
                        (This pertains to the type of Manual Starter Housing that sits over top of the flywheel)
                        (J. Reeves)

                        Lay the manual starter housing upside down on the workbench.

                        Wind the spring "counter clockwise" in your hands so that you can lay it into the housing, having the outer spring end hooked over the retaining pin. Make sure the spring is in there properly (You do not want it to fly out of there).

                        Holding the spring down, with pliers carefully bend about 3" or 4" (more or less) on the inner portion of the spring in towards the center of the housing. This will allow the pulley pin to enter the retaining hole at the end of the spring properly.

                        Lay the pulley down over the spring, making sure that the pin on the pulley is secured to the retaining hole on the end of the spring. Install the spindle (center bearing gizzmo), bolt, nut, etc, whatever your particular manual starter may use.

                        The cord (nylon) should be roughly 72" long. Have a figure 8 knot in one end. Heat the other end so that you could form a point on it, wiping it with a rag when it's burning or hot to a melting point.

                        Now, with the starter housing still upside down, keeping a firm grip on that starter housing and also the pulley, start winding the pulley in the normal counter clockwise direction. Wind it as far as it will go, then carefully let it back off until the starter pulley cord hole is aligned with the housing cord outlet.

                        Hold the pulley there and insert the cord in through the inside of the pulley and out through the starter housing. Pull the cord through completely and get a good grip on it. Now let the pulley retract the cord, but hold onto the cord (don't let it fly in there).

                        If it's obvious that the cord is too long, figuring what will be needed within the handle, shorten it as needed.

                        Pull the cord out so that about two feet of the cord is exposed. Tie a slip knot so that the cord can't retract back.

                        Insert the cord into the handle and secure as needed, then release the slip knot allowing the cord to be withdrawn fully. That's all there is to it..

                          The only thing I will add to what Joe said is that the '58 uses a Ease a Matic starter, and it needs to be properly timed, compared to a normal Simplex starter. The difference with the Ease a Matic is that the sheave is oblong shaped, this provides for easier starting since you are using the non compression portion of the stroke to build up speed. Only works properly though if it is properly aligned with respect to the crank.

                          The rope for the 10/15/18hp motors use a 7/32" diameter rope cut to 72 1/4" long. If you have 1/2" of rope protruding from the figure 8 knot, the starter should be properly timed. The embossed arrow should line up with the mark underneath, if it is off, simply trim the rope so that the arrow is aligned with the mark.

                            High Trim.... That slipped my mind, thanks. Align the rope notches and all will be well. Just makes it easier to pull over.

                              Actually, it'll pull over w/the same ease if it's not lined up, but you'll have to pull the rope further out to engage recoil pawl to flywheel.
                              It's almost beyond the point of bearable how torturous it is to try to have any dignity in being a Vikings fan..
