First try pluggin in the aerator line to your bilge pump to see if that still happens. If not, then it could be an aerator pump failing.
If that does not work, then contact [url=mailto:Service@BassCat.com on Tuesday] Service@BassCat.com on Tuesday[/url] and be sure to give them your serial number.
The BP-400 is the lesser of all of those BP dashes. It worked fine, though could develop some issues. The screen was hard to read because it was a dot matrix screen, and the overlay etched on them. The rolling display was one many did not understand also.
We will be glad to assist you.
