Re: A couple more questions bear with me
If you are uncertain as to when the lower unit oil was last changed,I recommend draining and refilling with new.Drain by removing the lower drain plug and then the upper vent plug just below the anti-ventilation plate.Note whether there is a milky color to the lube which would indicate water intrusion.<br /><br />Using either OMC hi-vis or after market hi-vis lower unit lube ,refill from bottom hole until the lube weaps from the top vent hole.Then without removing the lube tip,install the upper plug and then install the lower.This method insures that no air gets trapped during the refilling process and the fill level is topped off.Your lower unit will hold about 22 oz. if I remember right.Also make sure before performing this task that you have new nylon seal washers installed on both plugs.<br /><br />After engine use in muddy or salt water,it is recommended to flush the engine using an flush muff fed with city water and running the engine at idle speed for several minutes.
