Gearhead question

Those are the air filters

It could just be a white foam sleeve over airsep type filters, like a pre-filter. The aquafina water bottle for the coolant overflow is a nice touch on the port motor however.

The photos do not show solid plastic covers over the air intakes. The solid appearance is a result of perspective.
The filtering material is kept in place via a mesh over lay. The mesh has large diamond shaped "holes" that have a minimal impact on airflow, and when viewed from the side they may appear solid. When you change your perspective and look squarely at the covers you see the actual configuration clearly. I think that is what RER was trying to illustrate for you with the photo he attached. I hope this helps clarify what you are actually seeing.

Yes, they are standard paper filters that you see on a lot of engines (non washable) and it's basically a metal cage that keeps the filter pleats protected and gives the entire filter strength so the paper doesn't crush from the housing that keeps it on the engine.

I can't comment on the why's, but they are surely air filters. And we don't suffer any restrictions on ours.

Still waiting for a comment regarding the white hose clamps.

Some reading of interest, perhaps.

Good eyes.

Must have used the last of the white paint on those single, white hose clamps?

Regarding the OP:

Check out the filters being used.

P.s._ Does seem to state "Walker Air/Sep Systems", lower right section.

No, it is not weird.

There is a lot of weird stuff in this thread that begs a lot of questions we are not allowed to ask but maintenance based on thermal cycles is the least "weird" thing so far.

The guy working on the assembly line at MTU did "such a thing" when he installed the crankcase breather ...

The implication that this might be an unacceptable practice is my idea of "weird."

The hose clips might have once been on a hose that was painted white and has been replaced, single hose clips are find when no pressure as such is present.

If the colour and quantity of the hose clips causes you consternation I would have a long hard look at something else on those engines that will be much more attention grabbing than a hose clip.

I would start at the two 2/0 red positive DC cables going to that Breaker chafing on the plate cooler Starb. Motor and then at the other cabling with out chafe gear on the girders by the starters . I've resisted joining this thread due to the first question posted about the air cleaner "can you identify this" ???
" Tuna Tubes" ?? The OP has stated that he has owned vessels in the past and to my best recollection I just don't remember any engine that didn't have silencers or intake filters but maybe this poster enjoys the attention of a
Neophytes question. Just saying...
