The one to the right is the hydraulic pump. Provides oil pressure for the cylinder at the rudder. The hydraulic pressure from the pump is electrically controlled. The helms wheel is mounted on another hydraulic pump (muscle driven one) so I have two options for steering. At the moment the electrical one is out of function and I need to check it out. The sea water pump is on the same shaft that drives the diesel pump. The blue hose on the left is for sea water.
