This marine model is a fully polyurethane-potted version of the M400 ECU. With an IP67 rated design, it is reliably waterproof and weighs just over 900 grams.
Marine versions are specifically suited to applications in harsh environments - like water, dirt or vibration. They are suited for use in PWCs (Personal Water Craft), boats and off-road vehicles.
All functions and upgrades will be the same as the standard ‘hundred series’ ECUs.
For detailed specifications see the standard Gold Box M400 ECU pages.
