Brush wear and commutator wear is excessive on this thing and soon it will be done. Then I will need to replace the pump or motor. Only 2000hrs on it.
Try cleaning between the bars.
Great advice, Ski. You're a great resource for this site.
On another subject, Simrad's customer service response is typical of a company that couldn't care less about its customers, which has been my experience. I would never recommend their products to anyone.
