MOB+ can be installed directly in most boats with multiple engines. If your boat comes prepared for/or you have an existing kill switch, MOB+ can be connected to existing wires.
Some engine manufacturers such as Yamaha use a multi-pole kill switch in cases with multiple engines installed. In this case you will need a MOB+ Multi Engine Harness which is available from all our retailers.
The Multi Engine Harness can also be used to wire a kicker engine in a way so that both your kicker engine and main engine will stop in a man over board installation. Each engine can still be run separately if needed.
Please note that all engines will need to share a common ground potential (Negative (-) pole on the batteries will have to be connected).
