Electrical question

[Ray Durkee]

I used the Yamaha 1000 generator extensively for the last 6 months on my cruise down through central America and the Panama Canal and it worked very well. I thank you for your advice. Very quiet (you cannot hear the thing a boat length away) and it is quieter than my diesel. In the tropics, it is a godsend as you do not want the heat in the boat from the diesel. I just set it up when I leave for shore and everything is charged up when I get back. This Yamaha is a terrific unit--uses about .1 gal per hour (runs about 6 hours on a tank) and weighs 27 pounds.

One issue: I seem to be going through engine and prop zincs at a very accelerated rate. Should I be grounding this unit to the water or is this just something that happens when you use a generator?

A cheap receptacle tester (circuit analyzer) works well.
