1960 evinrude fastwin 18hp water in lower unit

[illininfo]

I pulled the lower unit to check water impeller and found a couple of things wrong!! When draining the gear oil I found water in the oil. When I dropped the lower unit there is oil all in the area where the water impeller and water intake is at. The impeller looks good, but I am not for sure where the oil is coming from!! Where do I need to look and and what might need to be replaced. I think I will replace the impeller reguardless since I have it apart this far. Thanks

Well, if there is water in the gearcase, oil can be leaking out the shift rod seal and/or driveshaft seal if the motor is stored horizontally. But I'd suspect the oil you are seeing is normal - just unburnt 2-cycle oil from the fuel mix which exhausts through the leg. You'll most likely need to re-seal the gearcase which involves removing the skeg to get to the shift rod seal and propshaft seal. A replacement seal kit is available right here on IBoats or at any Johnnyrude dealer.

Before you start tearing anything apart, check that the gaskets under the drain/fill and vent plugs are fresh. Never reuse them. The most common cause of water intrusion is reusing those gaskets.
