What is the K&N Filter cross for Indmar Part# 525022 or S525022?

A few searches here didn't reveal the answer. Upgrading the Flame Arrestor to K&N Filter / Flame arrestor. Not sure on PN for my LTR 330 equipped 1999 Prostar 205v.

Indmar Part# 525022 or S525022 seems correct

Anyone know the K&N cross number?

Are there other filter / flame arrestor options?

Got mine with 870 hours, 3 prior owners, and a THICK coating of oil & sludge on throttle body and presumably in the intake. Will be disassemblying & cleaning but would like to keep it clean going forward.

Not sure if it's the same,
I have 2002 Xstar 5.7l indamar I run K&N HP 3002

I think most people on here run Napa Gold if I remember correctly so prob won't see much feedback

Hope this helps

There should be a number on the back of the flange that is the K&N number.

Here is the list of K&N marine arrestors:

Looks very similar to K&N 59-5023. From the Bakes website, I used the 525023 Mfr number, ran that through Google and got several hits for the 59-5023 flame arrestor.
Search of the K&N website shows listings for Indmar engines. They have a number 59-5020 which looks very similar, but has a molded in curve.

Hope that helps.

Yours was coated with oil because the previous owner or whoever serviced it didn't clean it. These all collect that stuff and the easy answer to "How do I keep it clean?" is to clean it annually. You should be able to spray carb cleaner in from the back or set it in a pan with gas or mineral spirits for long enough to make the stuff come off. I use clean gallon paint cans from Home Depot to soak parts but I'm not sure this will fit through the top. Maybe if you tilt it as it goes in....
