      Merry Christmas to all my fellow outboard enthusiasts!  This relative newbie to hobby finally found his dream antique outboard…an ELTO Rudder-twin. I need assistance in determining the year it was built as well as the most appropriate sources of literature for repair, parts list, and general info.  The Rudder-twin is in generally good condition and has no dents in the tank.  The S/N is “C12315 …not sure what the C designates.  I am guessing that this is a 1922 or 1923.  Any help would be greatly appreciated as to where I can find literature.

            Tubs, you have posted some great videos that I’m sure will be helpful to me and restoration of this rotor twin! I’m sure I will watch them over and over again to learn from you. Question, if I do take down the engine to the bushing mentioned where do I get the replacement bushing at? Also I know the wires are all bad in the coil and will be replaced as in the video. Where do you buy the old antique looking wires for the spark plug wires? And also, if I do want to take down the cylinders, where do I buy the gasket sets or do I make my own gaskets?

              Your motor should have a brass timer bushing and they are
              normally still good. Its the later motors, where they used a
              pot metal bushing, that the failure occurs.
              I suggest you don’t remove the cylinders unless you have a
              good reason. The rings are now seated in the cylinders.
              Disturbing them could result in some compression loss.
              Replacing the rings with new ones would require as least
              hoeing the cylinder which increases the piston clearance
              in the cylinder. Move the pistons so the rings are
              accessible through the exhaust ports. Take a small screw
              driver and push on them to see if they are free. If they are
              I would wait to till you try to start the motor to see if there
              is an issue that would suggest the cylinders need to be
              removed. Any gaskets that you may need will have to be
              made by you, however there is a guy on eBay making
              gaskets for old outboard motors. You may be able to work
              something out with him. Cylinder gaskets must be close
              to the correct thickness. If not the exhaust manifold bolt
              holes wont align.
              Since I did the coil repair video a new, inexpensive. coil has
              become available. Search eBay for (2 spark Replacement coil
              for early ELTO type outboard motors).
              An internet search for “cloth covered spark plug wires” should
              provide you with some choices for suppliers.

                As always, wonderful sage advice!  I have not spent any time at all on the motor since I just picked it up,  but I have noticed that the flywheel only turns about 1/3  the way in either direction and the prop turns as well.  I have no doubt that it can be many things including rusty cylinders, crank shafts, gear boxes, etc… but the pot metal bushing comment in the video did get me thinking.  I will attempt to pull the flywheel as well as continue to soak the cylinders.  Even if I do not get it running, it is my perfect display motor and can’t wait to give it a little polish!  I have read so much valuable input you and a few others have taken time to share with this outboard community….a great big THANKYOU from us newbies!

                  You have selected the best approach in removing
                  the flywheel to investigate the timer as being a
                  possible source of the restricted rotation.
