      I just got done re-assembling the water impeller case, impeller, cover etc. re-placed the gear grease with the specified correct lube and now I have a trickle of grease coming out of the intake slots. I put in all new seals and washers correctly but there is an oil seal ring on the lmpeller lower case that I didn’t replace because I was told it was no longer available.

      Any ideas?

        The grease will cause the pump rotor to swell rendering it useless. Go to a bearing parts house and find a seal to match the prop shaft size. Hopefully there will be enough material to machine the pump housing to fit the new seal.

              Will the SKF 5569 fit into the water pump cartridge?

                Seal catalog will indicate in BOLD numbers the standard general purpose seal for each
                shaft size and seal diameter and height. Unless the application requires a nonstandard seal
                go with the common least expensive seal.

                The new seal will work if the shaft is smooth, round and concentric to seal lip.

                5569 is for a .999 bore and is .219 high

                  I believe you must pull out the waterpump cartridge to change the seal, I haven’t done on KE4 but on KF7 you must pull. You will need to make a puller.

                    This is what I put together to get a pump cartage out.

                    A "Boathouse Repair" is one that done without having tools or the skills to do it properly.

                        Nice. I made one as well. Not as fancy but it works.
