      I just picked up a 14K1 3S & a KD35. The K1 is 2.5hp & the KD is 4hp, both 1940 motors. Anyone have one of these motors? How hard are they to work on?
      Thanks,
      Jeff

        14K1 8821 Sea King 1941 model has poppet valve fuel mixer and sheet metal clamp assembly.Not difficult to work on.
        Mercury KD3S 1947 model rewind equipped postwar war model has Bendix magneto and anti friction bearings all of which can need work. Helps to have Mercury Service Tools to remove and install magnet rotor. A few self made tools and techniques helpful in disassembly
        and reassembly.
        The prewar Kiekhaefer singles are a little more complex than they appear. The fasteners
        are often mixed up or missing due to careless workmanship. Detective work needed to
        sort that out and to find correct replacement fasteners. Postwar models have same issues
        plus more complex starter, corroded bearings, and need to remove and replace magnet
        rotor when renewing upper seal and bearings.
        Some problems like a leaky gas tank (cast aluminum tank) are easy to resolve at low cost.. R

        1940 Kiekhaefer Sea King Single was model 8820.

          I am puzzled by 3S 1940 model…could you give more information? 14K1 and KD3S I am clear on.

            Is there enough interest in the Early Kiekhaefer outboards to justify a continuing Q & A with
            photo articles on such subjects as dealing with stuck powerheads, resealing cast aluminum tanks, removing stuck swivel pin, making the leather drive shaft seal?. If so, I will talk to
            Travis to see what is possible and what is not.

                Well, I am always interested. It would be nice to see a little more of the Merc stuff here without having to go to a whole different site.

                Long live American manufacturing!

                  Bill,
                  I agree! Mercury has different engineering than other firms. but quite functional!

                    leather drive shaft seal????
                    Oh yeah, I need more info, I thought something was missing on my KD4, I welded a skeg on this one and haven’t reassembled yet.

                      Leather was certainly utilized for a packing to seal the driveshaft on the early lower units, but the replacement is a rubber seal, and possibly adopted into production for the models after World War II. We do have a few of the rubber seals.

                      Regards,
                      Joe

                        Thank you Joe. Need to give you a call. These two are left overs from our friends collection. I’ll call soon, & yes many used cow seals, I AGREE!
                        Got an invite to see my friend Alabama, MUCH news to catch you up on, some good & some bad. I’ll call at late afternoon. Sold my Mk 50 to get stuff for my Mk 30 tiller.
