My Crappy Gear Lube Pump...

[MacGyver]

...Keep pumping about 50% lube and 50% air when I was refilling my drive today. Should I be worried about all those air bubbles getting trapped somewhere?

Any recommendations for a quality lube pump?

[DAREDEVIL]

As long as u fill up from the bottom of the drive,,,no problem. The air will go back out thru the res.

My Pump ,,,i bought in Walmart,,,for 9 bucks and worx 100 %,,,the bigger one i have ,,,( bucket pump ) is from harbor freight,,and also was cheap,,worx 100 %.

I think u need to check the pump u have,,and maybe replace an o-ring in it or a gasket somewhere.

Any pic ????

Yup, I always fill the drive from the bottom.

I'm thinking something like this for next time, with a few adapters.

Get a universal garden sprayer hand pump. I have the old style merc hand pump that threaded on. I installed the tube and fitting from the merc pump on the garden sprayer pump. Be sure the gear lube is warm it pumps easier.

I thought it might work with a variable speed drill on super slow.

Not saying it will not work,,,but i would do it by hand ,,not as lazy as u .LOL:bump:

[MacGyver]

Lazy........guilty :) Actually that Harbor Freight hand pump might work really well.

I use a delco electric fuel pump ( solenoid type ) I mounted it on a piece of plywood, connected two 6 foot rubber fuel lines to it, used the screw in type fitting from one of those crap mercury pumps and stuck gator clips on 10 feet of wire to power it from one of the boats batteries. It doubles as my engine oil removal pump as well.

[Offshoredrillin]

Modified sprayer.....I never thought of that.

Bmax holds a lotta oil and I feel for ya! I've never really used the small pumps in all these years. I've either used the sprayer and almost always use a 5 gallon pail pump.

Whenever I buy gear oil I always buy 5 gallon pails so this kind of pump is easiest for me.

I have a 2 gallon garden sprayer that I bought at the Home Depot (they make them as big as 4 gallons I think). Cut the sprayer off the end of the tube and clamp a short piece of hose and the screw fitting for your drive to it. Keep the squeeze valve on and use a rubber band or small clamp to hold it open for long fills. Now fill the tank with lube, screw in the fitting, pump it up and block the valve open, usually you only have to pump once and the thing is full hands-free in about 10 minutes. Total cost was about $20.

The Merc Pump always collapses the 5 gallon neck. Frustrating and messy. :cuss:

Rob, I have the one you have and it works great. I did not get it at your awesome price though. :(

Some good suggestions here for making one but if you want a primo system made specifically for the application and ready to run;

If it would make you feel better send me the 100 bucks and I'll send you a Magic Marker to write "MARINE GEAR LUBE FILLER UPPER" on it :sifone::sifone:

Your right, but, I have a garden shed full of the best Home Depot sprayers and none are as heavy duty and well purposed as this one.

Still saying your right though. :rolleyes:

I converted a 1 gallon garden sprayer to a drive lube pump. It works perfect.

Drain the drive AND the bottle.
Fill canister with about 3.5 quarts of drive fluid.
Pump pressure into the canister.
Fill drive from bottom.
When fluid comes out vent hole, but the plug in the vent hole.
Then keep filling until you see about 1" show up in the bottle.
Wait a couple hours, as a bit more drive fluid will creep up into the bottle.

Then top the bottle off with what's left in the 4th quart.

DO NOT put more than an inch of drive fluid into the bottle the way I describe. It will creep up and overflow. Ask me how I know that!

Works perfect, and I've got about $25 bucks into it including the garden sprayer and a Quicksilver drive fluid pump for the drive fitting only.

You will have to do this with warm (60-70*/room temperature or above) drive fluid.

Save your old drive fluid pumps though. They work great for extracting fluid should you ever get too high.

That's the same one I use Rick. I've never had any problems. Something is not sealing right if you're get'n air.

+2nd that.

[Geronimo36]

And my pail mount pump is only $25!!!:cheers2:

The sprayer is nice because if it falls over it wont leak.

One of the things I did not like about it was you always have to pour oil from the quart containers into the sprayer and if you buy 5 gal pails it can be a mess and a PITA. When you do enough drives it doesn't pay to buy quart containers or even 1 gal containers. You buy 5 gal pails, remove the lid, put the pump on top and pump until it's all gone then put the pump on the new pail!

I guess it's all about preference and what you're used to so it really doesn't matter either way! :cheers2:

When draining the gear lube is it better to do it after you use the boat so that the lube is a little bit warmer and drains better. I always do it when the boat is dry because I get paranoid about even getting 1 drop of water in the drive, but it takes for ever to drain (and yes I open the vent valve).

[Geronimo36]

It'll definitely help to run the engine first. You don't necessarily need to run the boat but at least run it on the hose for 15 minutes. Don't worry about a drop of water, it wont kill ya! 10-20 drops or a dribble..lol, yeah not good. :)

Another thing that I do if it's cold is I pull the plugs and let drain overnight.
