Lower Unit Lubricant
1980 200HP Merc. Black Max.
The lubricant is creamy in color, which I think is an indication of water seepage. Reading the repair manual, trouble shooting the problem is beyond my skills. Although the rest of the motor has been rebuilt, the lower unit is original and the only work done to it has been the replacement of the water pump and/or impeller various times, oil changes (lubricant) and replacement of the vent screw and seal washer. Is this something I need to address or not a big deal and just replace the lubricant monthly? Any suggestions on the repair? As always, your expertise is welcome and greatly appreciated. Thanks! ???
