This gear case for the KG4H and KG7H Mercury racing engines has been totally rebuilt. Included in the rebuild were all new driveshaft, propshaft, water pump, impeller, bearings, seals, driveshaft pilot, shims, fill and vent screws, studs, tab washers, nuts, water tube compression ring and bushed cone nut. The gears are used but did not show any wear that is why we reused them, they are original factory gears and not reproduction. The housing shows some minor dings and the skeg looks to have been filed and with a little bend.
