This Sierra oil filter, 18-8703, is made for 4-stroke outboards and is listed for Mercury and Yamaha. The canister is heavy-wall steel with an epoxy coating against corrosion. The thread is 3/4 inch x 16. It has an anti-drain-back valve, and a new o-ring seal is included.
Our take
The heavy-wall steel canister with an epoxy coat is what the maker relies on against corrosion on this filter. The 3/4 inch x 16 thread, the anti-drain-back valve and the included o-ring come together in one part.
