Re: Volvo Penta GL Not Pulling Water, Help!!
How did you determine the pump is not putting out water?
Did you pull the hose where it hits the thermostat housing to see how much water comes out?
With the muffs on and the water turned on, you will get no water past the pump if the engine is not running. What I would do, is to turn on the muffs and pull the inlet hose off of the raw water pump to make sure water gets to the pump while the engine is not running. This way you will know there is no obstructions between the drive and the raw water pump.
