Adding Cabin heat from a AQ140A motor
 

Have any members added cabin heat from the motor? I don't see any ports or access from the AQ140A motors water pump, but see many ports on this( used and neglected block) as circled in the attached pictures. I can add a electric water pump if needed to circulate the coolant water from the block. Since it has antifreeze in it, I wouldn't have to worry about it when I winterize the boat.
