Most anybodys should be good for that purpose.
At one time there was some discussion about the filters waterlogging with oil and causing the engines to run lean, I believe that was straightened out by increasing the micron size slightly.
I don't believe there is one set filter set that is preferred. Some guys here used Walmart, Merc, I have NAPA with Merc reference numbers.
A water seperator-filter (one with a drain tub would be nice) mounted, that looks a lot like an oil filter should do the job.
