G Series Heater Leaking....

[keith]

Does anyone know if these new G boats have a shutoff valve for the heater? I am taking on water and it's coming from mid boat running down starboard side into rear compartment. Only while running and it's warm water.

I don't believe there is a shut off but you can access the heater by removing the bow passenger backrest (the one directly below the windshield). It is held on by push in plastic Christmas tree clips.

If you want to bypass it, you can just run a short hose between the two heater connections on the engine. They have red hoses from the factory.

Thank you. Fixed temporarily.

Isnt the heater part of the closed loop on the <2015 models?

That is true on the 6.0L engines (like yours) and on the 550 engines, but not on the 2016+ DI 6.2L and 5.3L engines. They do not use closed cooling anymore since the heads and the block are no longer dissimilar metals. They are all raw-water cooled.
