Walker Airsep CCV

[Mike Mason]

Qsb 5.9 380’s. Started to notice a very light sheen of soot on the port and stb transom corners. Never saw this before so I wanted to see what was going on. Did some reading on the factory installed Walker Airsep systems and realized I needed to let the motors breathe a little better. Cleaned the external filters and changed out the internals. 1500 hrs on the originals I am sure.

All good. Ran the boat 100 miles this week and clean as a whistle.

Just a note for anyone who hasn’t changed these yet. It’s easy. Also, these seem a bit over engineered and I know Tony sells a similar system that gets the job done just fine.

On a side note has there been a good way to clean the coalescing filter? Call me a tight arse but I would rather clean than replace.

Although I am not a Walker fan, on the QSB 5.9 they do a decent job (not so on the any of the mechanical B’s) but are overly complex and quite expensive to maintain on a per engine hour basis.. Yes, engines need to “BREATH” easily.
