A Sierra canister oil filter made as a replacement for Mercury Marine engines. It is listed for 135, 150, 175 and 200 HP in-line four cylinder Verado outboards and has an anti-drain-back valve built in. The canister is heavy-wall steel with an epoxy coating for corrosion resistance. The thread is 24mm x 1.5. Cross references include Mercury 35-877767K01 and 35-796546T.
Our take
The heavy-wall steel canister with an epoxy coating gives this filter two layers against corrosion, which counts on an outboard that lives in a damp cowling. The 24mm x 1.5 thread is worth matching to your engine before you buy.
