The connectors coming from the black boxes look like they are OEM style,my Yanmar do not have these boxes,could it just be 2 relais that can be installed by someone to move an electric device up and down or something like that ?
Do the wires from the boxes run to the main connector ?

You could be right about the glow relais,because mine Yanmar does not have the glow device installed,I assume it is an option,but then again it should be in the manual.
the start relais can be seen on the picture ,its more down and a little to the left ,its a small relais that armed the big relais at the starter.

Yanmar
They are part of the low water level sensor and low sea water flow sensor. They cut out any momentery operation of these, like getting lots of air in the sea water when in rough seas it is to prevent the alarm giving lots of false readings. You wont find it in any Yanmar manual.
