Mercury Quicksilver Gear Case for KG4H, KG7H or Mark 20H.  This case has been rebuilt with a new bushed cone nut, water pump cartridge, impeller, bearings and seals.  Overall good shape for a used gear case.  Nicks and dings, oversize vent screw. The drive shaft needle bearing installed is a B912 not the GB912 as factory installed due to the GB bearing being loose when installed. Comes with new tab washers, compression ring, water tube seal and attaching nuts.  The used gears are excellent 1:1 ratio with good driveshaft and propshaft.  Filled with Lubriplate 105. The 20H did not come with a bushed cone nut but we raced with these in the 1950's and '60s.  Shipping cost will be added which are estimated with insurance to be about $30.
