Welcome aboard

Are you talking about lower unit gear lube? or fuel/oil mix?

Yep. I use wal mart stuff.. you can get it on iboats too.

You need a pump for it and you remove the lower fill screw and the upper vent screw and pump it in from the bottom pumping it until oil comes out the top. Make sure to replace the seals on the screws. While you're draining the oil you can assess it; milky oil is bad, it means water intrusion has occurred.

Just drain the oil by removing the plug located at the bottom of the "bullet" and open the vent plug. The drain plug is located at the very bottom (not on the side which is the screw for the shifter) with an allen screw head. No pump is required unless you wanted so then you can just pump it out from the fill or vent plug.

Use "Marine Lower Unit Oil" with certain additives for marine environment, just pump it in the bottom drain hole until it comes out the top vent hole, replace screw plugs, you're set to go! Walmart carries the oil and the pump. Take your drain screw with you to make sure the pump threads match up right. I believe there's 2 or 3 different drain screw threads. Good Luck!

So how does that work when you're ready to disconnect the pump? I mean the drain plug is located at the bottom of the bullet which means as soon as you unscrew the pump hose oil will drain back out.

that's just not true...

If you replace the vent screw, it will not leak... such has been my experience changing lower unit gear lube..
Squeezing it against the force of gravity isn't very easy -- been there, tried to save 6 bucks on the pump, didn't work.There is a reason the MFG suggests doing it this way.
