Hello Tony, what are your thoughts on paper-element air filters in the marine environment? Keep making your videos

[@SeaboardMarineIncVideos]

We generally replace the paper filters with S&B cleanable filters. The paper filter really doesn't belong in a marine environment.

​@@SeaboardMarineIncVideosAnd "synthetic" filter medias do?

Oh look. It's an IDLE TEST. Since all no-load engine operation is idling. And it PASSED. Most engine manufacturers today "discourage" engine idling that is "excessive" even when the engine is in mobile machinery and subject to some loads. But not "Cummins Marine" or at least a "Cummins Marine" distributor. Or whatever this "shop" is. Of course if the "aftercooler" needed "service" it must not be a brand-new "factory fresh" engine. Or somebody didn't properly prep the engine for storage and store it "by the book". I have to laugh at an "electronic" engine with a "manual shift" PTO clutch unit "gearbox" on it. PTO is the proper term for anything that is not a power transmission bolted on back - or front - of a "stationary engine" even if its "marinized".
