  • A Great Upgrade!
Size: 3/8 inch Swivel/10mm/8mm
For as long as I can remember, putting fluid in the lower unit was a pain. Trying to screw in the adapter would have the tubing come off the pump and spill the fluid on the floor. This swivel adapter completely eliminated the problem.

  • Needed modification to work with Mercury lower unit
Size: 3/8 inch Swivel/10mm/8mm
Handy set of adapters for pressure testing outboard lower units. The longest one for use with domestic outboard lower units such as Mercury I had to cut three threads worth off in order to get it to seal to pressurize a lower unit after replacing seals to check for leaks. Once I did this it worked great. ... show more

  • Really useful but it leaks
Size: 3/8 inch Swivel/10mm/8mm
This leaks gear lube. It's not a lot of lube, but it is more like six or seven tablespoons for a quart of lube. Messy. Still, it is very, very useful. I no longer have to squeeze or pump lube into the lower unit. I use this adapter, some tubing, and quart of lube to fill the lower unit. Just hang the quart of lube upside down at a point higher than the upper vent of the lower unit. It will fill itself through the bottom fill hole. You will need to put a small hole in the bottom of the lube bottle to vent air in as the lower unit fills. Very useful little item. ... show more

  • No Mess
Size: 3/8 inch Swivel/10mm/8mm
No oily mess while changing lower unit lube. The only thing I dislike is “ I wish I knew about this product years ago”. Great product, a must have.

  • 1 out of 3 leaked
Size: 3/8 inch Swivel/10mm/8mm
I went to do a leak down test on my outboard gearcase and the part that has the barbed fitting leaked air. It was basically useless for what I bought it for.
