[C320-list] Perkins Perama M30 Engine Air Cleaner

[Warren Updike]

The M30 air intake does not have a filter. This I learned from http://www.tadiesels.com. The have a guy with a British accent knowledgeable about the M30, and he told me no filter and does not need one. 
One Tip, when winterizing on the hard, tape or plug the exhaust thru-hull and tape over the air intake. This will help prevent moisture in the air from condensing inside the engine.

The two manuals you reference are all that I've seen, in addition to a spec sheet that was probably part of sales info.

The M30 has no zincs. Not sure why that is; but, doesn't seem to be an issue.

I’ve only had my 320 for a little over a year and, while I was thinking of checking to see if there was a filter in that box, it hasn’t come to the top of my priority list yet.  The last air filter box I opened up did not have a replaceable filter element inside, just the metal screen on the outside and a metal baffle inside and neither really needed any cleaning.  I asked a diesel maintenance guy in the marina and he was the one that told me  marine engines aren’t exposed to the same contaminants as road vehicles are.

While on the subject of the Perkins M30, I have only been able to find two “manuals” specific to the engine.  One is a very simple two pages that tells how to start the engine and gives amounts and types for oil, transfer fluid and the like.  Very basic info.  The other is the full shop manual that gives very in depth information on disassembling and reassembling the engine.  I haven’t found anything in between these two extremes.  I’m looking for a basic maintenance guide; something in between these two extremes.  

One specific piece of information I haven’t been able to track down is wether or not the water cooling system on the M30 has any pencil zincs inside and where they are located.  Have you found/changed zincs on you engine?
