Two complete Mercury Racing 500efi engines. They are being sold as rebuildable cores. They do run but one is getting water in the #8 cylinder and runs rough. They have approximately 500 hours on them. Bottoms ends are still factory sealed.

In 2017 (75 hours ago) these engines got all new fuel pumps (electric and mechanical), new injectors along with ECU flash for the injectors, topends were done at the same time with new Manley inconnel exhaust valves, stainless intake valves, new comp 292 springs, etc.

These are the latest serial number range so to my knowledge they were assembled with the Manley rods.

Currently still in the boat. Winterized them today. Pictures are from Today. Can have them out of the boat at any time.

These engines are 100% complete as they would have come from Mercury but are being sold as rebuildable cores. They are not ready to drop in a boat and go

$12,000 OBO gets the pair
