I have a 1999 Johnson 40 hp 2 stroke, model J40PLEEA. I just picked up the boat with this motor at the end of last season and I haven't spent much time with it yet and am just getting into the service manual. It looks like I have a one piece "recreational" filter that just gets replaced when serviced. However, on the online parts diagrams I can find, I only see replacement parts for a "commercial filter". However, the main body of the commercial filter does not show up in the diagram. I'm looking for where to buy either a whole commercial fliter or replacement recreational filter for this boat.
