Finished the rebuild (for now) of the 68 Evinrude. Rebuilt the carburetor with a BRP rebuild kit. Solved her idling problem, but she was hardly pumping any water, and water was pouring out from under the shroud. Also, gear oil leaking out of the exhaust. Did some research and with help from chrysleroutboarddude on Youtube, new and used parts, and some OMC marine special tools, I rebuilt the lower unit completely. Discovered that the "mechanic" the previous owner had used did some interesting repairs. The water pump housing was from a 6 hp model, bored out with no seal on the top end, and the impeller was toast. Lots of crud in the water tube and thermostat as well. I tore the whole thing down. The front weep hole on the lower unit case was completely solid with crud, and I had to drill it out. Amazing that water didn't collect there and break it by freezing, Next, I sandblasted and repainted the case, propeller, and skeg. All new shift shaft seals, clutch dog, impeller, impeller housing, wear plate, upper and prop shaft seals. Thermostat was cleaned, tested, and whole water system cleaned. New gasket made and thermostat reinstalled. Front motor mount is broken, but this will be replaced this winter. Tested successfully in a barrel, then taken up north to the clean waters of gods land, where she performed well after fine tuning the idling of her rebuilt carburator. Turned out to be a nice motor. More to come on that front motor mount...
