Looking for oil drain hose

[SSTKO81]

Good afternoon, I’m trying to find an oil drain hose kit that will make my oil changes an easier, cleaner job. I see the kits offered on line and even in Oreillys but I’m not confident in what fits my engine so I don’t want to buy the wrong part. Mine is a 1981 sea sprite with a mercruiser 140. Curious what others have used or if making one myself from off-the-shelf parts might even be an options.
Thanks
