My first time here. Just purchased a 64' Evinrude Sportsfour 60hp. Runs and starts easy. Has a hair line crack in the lower unit. Was hoping some JB Weld would hold up. Was also wondering about the water discharge. Looks like it was just "spuddering" out the engine. Is that normal for these old engines? Don't have much to spend on repairs, so any work would probably be done in the garage. If a new water pump is needed, could someone help with a services manual copy of the procedure?
