    Per Factory Specs MERCURY KD-4 should have left factory with a 3 Slit pump intake and a rubber vane type (ROTEX) impellor.
    Why some one would swap out parts to older less reliable Oscillator (Hockey Puck) style water pump is a mystery?
    I usually have the opposite problem? 1940’s K motors with newer 3 slit pump intake and rotex impellor, when the motor
    Left the factory with 16 square hole intake, and oscillator style pump. Rumor has it that the 7 slot intakes were done by hand
    Using a hack saw blade at factory?

    I’ll post some pics of Lou, “Green Thumbs” making seals from leather.
