Explanation how to change lower unit oil on 9.6 hp Sea king outboard/ what oil to use to do it??

On the lower unit, look for two large screw plugs, one at the top and one at the bottom. Remove both to drain the old lube.


You want 90W gear oil for the replacement. Insert a tube of 90W firmly into the lower hole and squeeze the tube until the lube starts flowing from the upper hole. Keeping the tube in place, replace the upper plug, then the lower plug.Explanation how to change lower unit oil on 9.6 hp Sea king outboard/ what oil to use to do it??
Also DONT FORGET to put the washer back on in the fill hole. Make sure it is there. without it you will shell that lower unit pretty fast.
