I noticed the center compartment had water in it when I shined a flashlight from the back. I took the motor apart and cleaned out the 3 compartments. I lubricated the magnet on the shaft and reinstalled it. It appears that the round rubber seal on the center compartment was leaking from where the shaft exits the compartment and attaches to the propeller. I just coated the magnet in the shaft and put some pet jelly behind the propeller. I’m sure this will leak again and I will need to replace the entire motor. The motor is pretty inexpensive at around $20 online and $38 from Sears parts store.
