Keyless start: power consumption ?

[Vronsky]

Would like to know how much electricity (mA?) the keyless start system drains from the battery when the engine is shut down.
Boat's going into winter storage for 6 months in a couple of weeks. Battery is a 100Ah semi traction model: want to know if the system can drain the battery in this period.

Thanks,
V.

Not sure.

But surely your boat has a master battery switch? Just turn it off. Then nothing can drain the battery.

My battery comes out for the winter.

Of course.
But there is a small black wire coming from the engine loom and directly connected to the battery, understand it's related to Keyless Start/FOB.
Other thing draining the battery directly btw. is the solar charger controller.
We're both talking mA's here, but stil could matter over a period of months.
