    03 GTX SC Impeller Housing Issue?

    Can an 04 GTX SC impeller housing fit on an 03 GTX SC? The reason I ask is my 03 GTX SC is cavitating and I suspect the problem is the impeller housing. I've already replace the wear ring and the impeller looks fine. The impeller housing is plastic in the 03 model but was changed to aluminum in the 04 model. Plastic just doesn't hold up with all of that torque. Any thoughts or suggestions?

    Yes, it will work/fit.

    Getting any water in the hull from the carbon ring? When the carbon ring wears, it will sometimes allow air from inside the hull to enter the pump tunnel. Have a look. --Jeremy

    I kept it in the water for 2 days during the Memorial Day Weekend and I didn't have much water draining out. Maybe a cup or two, nothing abnormal for a weekend on the water.

    Is the carbon ring outside the hull? Do you have to pull off the pump housing and the drive shaft to see it? Is there an easier way to get to it?

    I have a complete metal pump with new wear ring available.
    Just install your impeller, bolt on the pump and go.
