milky lower unit oil

[kfoster]

The oil in the lower unit of my merc 75 is a milky cream color when I drained it last. Any ideas? New seals? Boat seemed to run fine last time out.

Yep...I'd say it's time for new seals. Like ODDD1 recently said..."Water ain't a good lubricant!"<br /><br />How about providing the year of your Merc...that will help determine what needs to be done...and if you're so inclined...how to do it.<br /><br />Walt
