Got a 02 outback, blower motor went out in. Pulled the back cover an it's got 2 vent hoses but only 1 motor. Is that right or does it need 2 motors? Bought the boat used so didn't know if it needed another. Also how far up the floor should the vent hoses go? 1 with the motor attached goes under floor, there's a PVC pipe there but it's not attached to the flex pipe should it be? The other flex line just vents in the rear compartment, is this the way it's suppose to be? Anyone know?
