My neighbor is an old boat mechanic, and has a neat setup for pumping drive lube into an outdrive, much better than the $10 manual pumps that screw on to the top of the 16oz plastic bottles.

It's a steel tank, about the size of a large garden sprayer. He puts about 2-3 gallons of lube in it, screws on the lid (that has a hand pump), and pumps up the pressure. He attaches the hose to the lower unit bottom fill hole, then releases a valve, and in about 2-3 minutes, lube is coming out the top hole. No mess, no pumping!

Where can I get one of these things, in case my neighbor moves out of town?
 
Why not just get a cheap garden sprayer and attach the proper fitting in place of the sprayer nozzle. Plastic body of the sprayer should be compatible with the outdrive lube. Sounds like such a good idea I might try it myself.

Hmm. Ace has a 1/2 gal garden sprayer for $8. I'm tempted to give this a shot. Maybe if the wand was cut off and the hose from the useless mercruiser pump clamped onto it (with a real clamp, not the crimp thing it comes with that doesn't hold), it would do the job.
 
OK, not a bad idea. I think I'm gonna build one. Although, I won't be able to try it until next November...
 
The only downside that I see is that it will be a little more difficult to keep track of how much lubricant you have pumped into the outdrive. But then I never seem to use the published amount anyway, so this probably isn't a big problem.

We use a 1 gallon pump.
Bought the kit and used the plastic adapter.
Works great.
We do two drives in less then an hour.
The slowest part is getting the old stuff out.
 
I thought I would dust this off. I just today changed the drive oil. I bought a 1 gallon sprayer at Ace (they didn't have the 1/2 gallon in stock at the store), sawed the wand off, clipped the filter off the bottom of the intake hose, and clamped the hose from the cheap Mercury pump onto the end of the wand. Worked fine. It wasn't fast but it was certainly easier to squeeze the trigger on the wand and just stand there after pumping the thing up several times. Cost: $14.
 
Really? My store only had a 2 gallon unit on sale for $9. I was tempted to save $5 but didn't want something huge. I have a box I keep this sort of stuff in and a giant sprayer won't fit in it.
 
Good idea! Hint, depending on the type of drive, get the sprayer that will hold not only the needed drive fluid but have a sufficient volume to compress the air so you only have to pump it up once.
