    Louis, or anyone in the know about the subject rewinds
    can you read my last post on the link below, and
    tell me what the “guts” are suppose to look like,
    as far as the number of the dogs, how the rope was
    attached, etc. Thanks.

    I posted to that link already, with my thoughts on why the recoil pawls hit. That’s normal, when the recoil is off the motor. See my post on the other thread, for how to check it, off the motor.

    Long live American manufacturing!

    KE-3 MERCURY    Any tips on removing the water pump cover plate? The manual says pry up on the hub through the shear pin hole . I’m  a bit afraid of damaging it in the process. Anyone done this ? Just thought I’d ask before going ahead. Yes I have removed the circlip. Nice little motor. Ready to go, but i just need to check this.

    Also is there a source for these old impellers?

    Thanks
    Dave

    I’ve worked on very few Mercs. I’d start a new thread with your request,
    and photos if possible, to get the best response.

    Aligne the drive pin with the notch and push the pin out thru the notch. Method 1) use two punches of appropriated diameter (one on each side to pry up on holes in drive hub) Method 2) Polish corrosion off exposed portion of prop shaft, lube  and press it out of water pump housing. The SLAM the end of housing on wood surface. The INERTIA of the heavy brass cover disc will pop free of the housing. ( I use the end of a 2 x 4 standing on concrete floor to get a good solid wood surface)

    Take your pick I have used them both. Pryin does not work if cover is really stuck. SLAM works on the toughies.

    Skunk Juice and Heat if your preference is the flam wrench.

    Seal is 4923 and is always a bear to get old seal out. Which explains why the seal is always bad.
