Oil Change Device
As you can see, everyone has their favorite device for changing oil. Which one is the "best?" Depends on how you think about it. I use a high quality brass hand pump that I find perfectly adequate to change oil, and many other tasks around my boat. While there are probably "better" devices for sucking out the old oil from engine and transmission, many are more expensive and most are single purpose devices. My hand pump is also useful for sucking water out of tight spaces between the hull and liner, sucking water out of the bilge, moving fluids from one containter to another, and myriad other chores. And, it doesn't take up a lot of space. Whatever device you choose, do change your oil and filter frequently.
