This is a Mercury 200hp outboard EFI ECU with the part number 824003A26.

This unit has been parameter tested on a electronic fuel injection tester. This was also hooked to a computer on a Diacom system.

The pictures are included from the ECU tests.

All of the six parameter switch positions were tested, as well as the pressure transducer test from the transducer tube on the back of the ECU. The fuel pump driver was tested and works.

Note: this will not come with diagnostic paperwork. I am not able to print anything out because of the older style ECU tester that I use. On the Diacom diagnostic system it just tells me the ECU is good as you could see at the top right corner on the computer software screen.

Two different tests have been done on this ECU, both passing.

This will be shipped priority mail, and require a signature upon delivery.
