Does not come with a pump.
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
The Good: Changing the fluid in the lower unit is a very easy DIY job. This can save you hundreds of dollars each year by doing it yourself.
The Bad: You need a special pump to change the oil, and sometimes it comes with the gear lube. Unfortunately this product did not come with it. Luckily my neighbor had an extra one from changing the lube a different boat laying around and was able to use that.
The Ugly: If you have to go get the pump, that could cost a few extra dollar but is just an extra nuisance. The pumps are interchangable but you just need to clean it between uses (DON'T MIX DIFFERENT OIL BRANDS)
