I have searched to find the oil filter number for our 600's. The boat is not where I can get to it to see what filter it has on it now. This is our first oil change on our new boat. I have seen 2 filter numbers through my searches of 881126K01 and 840634K01. We use Wix Filters on our other Fountain. Can anyone tell me which filter number they are using on their 600's? Thanks!

if you use wix you should be able to use a napa gold 1060R, has better flow capabilities. and its made by wix.
