Is there a better gear oil pump out there?

[ShoestringMariner]

I don’t know what it is, but I can’t seem to find one that lasts. Is there a better gear oil pump out there?
I pulled mine out to use it today and it would not pump oil all the way up the intake tube and into the hose. The steel threaded coupler seems to have lost its O-ring friction and the hose fitting a sloppy.
I was hoping to use the same fitting for a pressure/vacuum test. No luck

I think this is the second one I’ve been through. Does anybody know if I can buy a quality unit anymore?? Everything I see for sale online looks like offshore junk that’s going to do the same thing.

I buy one from Walmart just about every year, but I use them for everything.. Last good one I had was a Mercury Quicksilver one and I killed it pumping 140W gear oil into a Troy Bilt Horse rototiller.

I did rob one of the fittings from one of them a long time ago and hooked it to a bike pump

I made one from a pump spray bottle.. Note the one in the picture is not mine but is a picture I found.

...... Last good one I had was a Mercury Quicksilver one .......

Mine is over 15 years old and still working, but I only use it for the boat.
It does look cheap and I am surprised it is still functional.

yeah, sadly I had to use the last Mercury one I had on the rototiller. The Attwood one I bought specifically for the rototiller project lasted about 30 seconds before it blew apart... But the Attwood one works well enough pumping what it is supposed to

Ok now that is the ticket!!!
I just picked up another one, the next time it fails I’m building one of these

I have a Merc one I bought like 15 years ago and put a hose clamp on the hose on the pump end this seemed to make it work consistently. I have a few of them for the Jeeps for gear oil & transfer fluid changes.

The tubing on my 90’s vintage Quick silver pump came off last week.

We’ll see how long a fuel hose clamp holds up

Good idea, I have a spare one of those myself. At the shop we have more robust ones, but for the average homeowner that will do fine.

been like this at least 10 years lol. without the clamp I think they suck air and don't pump right.

 

[ShoestringMariner]

I’ve got a stout clamp on it, but that silly little spigot is tapered. Why, I don’t know.

um, aren’t you supposed to fill the bottom port until it seeps out the vent?

 

[Lou C]

Cobra is different, you fill from the middle plug till it says full on the top plug (dipstick).

Ah ok, I learned something today

Same one.... no problem pumping but it makes a heck of a mess when it pops off.

I have been filling my lower unit from the top with a pump style oil can since I bought the engine new in 1998. Many here will squawk about how that won't work and how it will damage the lower unit, but I've been doing it for 22 years and 1,350 running hours on this engine without a single problem.

I filled the same way on my 1980's engine before that.

It's so clean and simple. Drain the oil, replace the bottom plug, fill through the top plug until full. No mess, no fuss.

I'll stick to the standard procedure, filling from the bottom.
I wouldn't want to be low on lube due to trapped air.

I tried that once. I’d didn’t seem to want to take any oil, or very little, and slowly. How do you manage, and what motor?

Get a large metal syringe with a thick needle, fill it with gear lube and squirt through the upper hole, there must be a gap between the needle and plug circumference for air to get in and fill the entire gear case, keep squirting new lube till exits the upper hole.
