[Electric Boats] Is Marine Certification Required?

 

Hi,

Arising from another topic, I was wondering if any group members have experience or knowledge regarding the marine certification of motors and charging systems.

My main question is, do electrical items that produce sparks need to be certified or enclosed somehow, if there is no gasoline or propane used inside the enclosed boat, and the battery box(es) are vented to the exterior?  

The motors that I am initially using are actually 12v DC generators, and are marine certified as well as fully enclosed with a steel band over the brush/commutator area.

My future plan is to add extra motors as needed, if needed, so I might need to buy only enclosed/certified motors, (if available) or enclose them in some kind of box. This then raises the additional question of whether a dedicated box is sufficient to eliminate the need for the motor or whatever having a marine certification label.

 

Any thoughts/facts?

 

Thanks,

John
