Closed cooling system for twin Merc 502 or 454

Help keep your engines fresh and clean if you're running in salt or help resist the freeze if you are in the north. I just pulled these off of my 1999 502MPIs because I neither run in salt or live up north. I have almost everything needed to install the complete system. Missing two exhaust manifold hoses and some clamps. Heat exchangers are in good condition. The mounts for the exchangers could use a sand and paint. $350 for the pair plus the ride.
