On both boats I owned (4 pumps), they've always had fuel in them. On the first boat (2) I had I changed the fuel pumps and shortly after I had fuel in the oil. Now I just change the oil every 25 hours. If I see metal on the magnet I rebuild the pump. The lobe and a washer are where it has always come from.

That is what I would do. Its pretty normal to see some fuel contamination. Use Merc HP gear lube or whatever you use for drive lube. I used to change mine yearly on my 525SC.
