I unbolted the seal plate from the motor and noticed the corrosion was so bad (salt water gen.) that the threaded part in the seal plate that the screws attach to broke loose, the plastic just crumbled.
I purchased the new seals thinking the leak last year was because they needed to be replaced but now since it doesn't make a good connection between the seal plate and the motor that was the problem.
I was thinking of replacing the seal plate but now as you see in pic. the motor housing that connects the two is deteriorateing (spelling).
The motor is fine but I am thinking I might need to buy a whole new pump.
