How Do You Pump Oil into a Lower Unit?
To pump oil into a lower unit, you will need a few tools and supplies. First, you will need a hand pump or an electric drill with a special attachment. Next, you will need a funnel and some clean rags.
Finally, you will need some marine-grade grease or lubricant. Before beginning, make sure that your lower unit is properly drained of all old oil. To do this, remove the drain plug at the bottom of the unit and allow all of the old oil to drain out.
Once the unit is fully drained, replace the drain plug and proceed to the next step. Next, locate the fill port on your lower unit. This is typically located near the top of the unit and has a small cap or cover over it.
Remove this cap or cover and insert your funnel into the fill port. Now, begin slowly pumping fresh oil into the lower unit until it reaches capacity. You may want to use a clean rag to help guide the oil flow into the unit, preventing spills during this process.
Once you have reached capacity, replace the fill port cap or cover and proceed to grease or lubricate any moving parts within the lower unit, following the manufacturer’s instructions.
