Description

OEM Mercury / Mariner engine control module (ECM / ECU / PCU) used on the Mercury 25 HP 4-stroke platform.

This unit was tested on the engine and confirmed to produce proper spark.

It was removed from a 2003 Yamaha F25ELRB, which shares the same ignition electronics used on Mercury-branded engines of this platform.

These engines were manufactured using Yamaha electrical systems, which is why this module also crosses to Yamaha part number 65W-85540-20-00.

Unit is ready to install and comes with a 1 YEAR WARRANTY.
