Nick,
I have an oval aluminum painted blue with K n N filter I paid $300 for if you want it I'd take $100 shipped. Fits 4150 carb or stock Mercruiser

Thanks but I have an MPI, not carb.

If you are still looking I have a new old stock K&N filter Flame arrestor that is for the Mrec 7.4 MPI. It was bought and never installed before selling the boat. text me 320 828 3483 I can get you photos
