I am sure others have been doing this for ages. But this worked out awesome when changing the filter on the boat. Always seems some oil spills out of the filter (even when using rags under the filter) or I end up touching the boat with my oily hands when trying to get out of the boat with the oily filter in my hands.
This worked great, cracked the filter loose, held the bag underneath and spinned it the rest of the way off. No oil in the bilge, minimal oil on my hands, and I was able to put the new filter right back on instead of having to get the old one out of the boat right away.
