I found a K&N filter service kit in the boat, I am assuming that's what on the motors. They are round and have a metal ring on top all held together with springs- well looks like a couple were substituted with wire. Sounds like a simple/stupid question but is it as simple as removing them, cleaning them and oil them? I have never done it. Also is there a consensus on what is best? Is there a reason to just replace?
 
Russ, yes, the turbo filters are re-branded by Airsep but are actually K&N so you've probably got the right kit. It may take a while to get them clean depending on how much stuff they've collected. The oiling goes pretty quickly but it's just as simple as that. There may be a secondary filter that you need to check once the big ones are off that I think needs to be replaced periodically, on the order of several hundred hours for mine.
 
Russ, found a little more info in a .pdf file I had saved, believe it is from the Walker Engineering site:


AIRSEP SERVICE INFO

Warning- Please Read

Standard AIRSEP units 1989-Present



Traditional AIRSEPS (AIRSEPS with springs or air filter frame) require NO MAINTENANCE. NEVER attempt to clean the inside of an AIRSEP unit, you will damage the material inside the AIRSEP and it will no longer function properly to process crankcase fumes or return liquid oil to the engine.

It may also cause engine crankcase pressures to rise out of the normal range. If you attempt to clean AIRSEP or por any cleaners, solvents, or other liquids into the AIRSEP unit, you must replace it to avoid damage to your engine.

You can and should only clean the Air Filter element using Walker air filter cleaning kit(s); DDF9000 for standard red filters, and BAF2000 for Walker Blue filters.

CCE AIRSEP units 2001- Present

CCE AIRSEP units are best identified as units without using air filter springs, and have a v-band clamp where the air filter meets the AIRSEP body. These units are serviceable, and are equipped with a disposable internal filter set.

These internal filters are removable and should be replaced every 500-750 hours. They CANNOT be cleaned.

See CCE service instructions for the unit you have listed in the "TECH" section of the Walker Website.



Air filters
on the CCE AIRSEP can and should be cleaned using Walker air filter cleaning kit(s); DDF9000 for standard red filters, and BAF2000 for Walker Blue filters.
 
Russ, sorry about that. This link let's you put in your engine and get back the applicable Airseps: http://www.walkerairsep.com/product_list.asp?productTypeID=1&engineMakeID=0&engineHPID=0. Looks like you may have either one, the difference is the shape of the filter; the newer (CCE) models have a taper and the older are cylindrical without a taper. I believe cleaning and oiling are the same as far as the outside filters go but the newer models have secondary filters that need to be changed at some point, albeit at a pretty long interval.
