Looking for a good running, COMPLETE 502 MPI or 525 EFI engine. Need everything with it, computer, harness, etc etc to drop into an older carb'd boat. What do you have? Thanks!

Got a fresh 525SC w/ 20hours on complete rebuild. Drop in reader with headers.

I have a complete 502mpi for sale . Call me 914-772-8956

I know of a complete 502 MPI with dry pipes for 8k

If anyone needs the ECU and harness for a 502 Mag MPI, I have one in the swap section.

Is this still available?

I have a complete drop in fuel injected Gen VI Mercruiser 502 Mag. Cool Fuel motor not VST. Motor has only 284 hrs ( if memory serves... under 300 for sure. haven't looked at it since Christmas) . Fresh water motor. Never rebuilt or opened up, all original. Not one component has been removed. Power coupler and bell housing included as well. This is a drop in, hook up and go motor. Has not been run hard in an offshore performance boat. Removed from a 26 family cruiser with Bravo Three Duo Prop. I have been looking for a hull to drop it in but not much luck in the last year of looking and posting adds. Not sure if distance is a factor .Your profile didn't show a location. I could meet you at the Border/Niagara Falls. I also have a friend who transports cars, cargo and boats all over the US. might be able to set something up that way also. Can arrange to have the hrs verified by Mercury computer as well as run the motor on video for you. Let me know if you're interested.

I also have a complete harness for a 502 MPI with MEFI . PM me if you can use it

Pm Brian41 he had 3 525 for sale complete and he's down to one with lower hours.
