I have a 1998 Merc 502 magnum mpi that is in need of exhaust manifolds. I am just looking for original replacements and have found two part numbers listed that appear identical but at much different cost. My engine serial number is 0L017050. The two part numbers I found are 807078T08 and 80708T10. All I can determine from the part descriptions is one is for fresh water and one is for salt water. The fresh water is about $130 cheaper. Anyone know if this is the only difference?

I have the original manifolds that came on my 2000 502, were ran in fresh water for one year before I put headers on, they look like brand new I have them in storage, will make you a deal on them if interested.

Thanks for the offer, but I went ahead and ordered some new ones and they should be on my door step today. I went with the E-Coated (807078T08).
