I am new to boating and have a 2004 Sundancer 340.  I've placed new zincs on her in May.  I have someone dive the bottom monthly and he has noticed that my prop zincs have completely eroded but the transom zinc is untouched.  Also he noticed a significant build up of barnacles and heavy growth around the trim tabs and upper part of the rudder only.  His feeling was that this could represent loss of electrical current from my boat or current from another source.  Does anyone out there have experience with this?

Do you keep your boat plugged into shore power?

As your prop zinc deteorates faster than your transom zinc it indicates that the electrical connection between the transom zinc and engine block ( shaft ) is poor or broken. Normally a green wire connects all metal hull fittings together and to earth ground via your shore power cable. Check and clean all these connections. If you find your transom zinc begins to errode quickly after you have reestablished your grounds you my have a dock neghibor leaking current. I would suspect an old wood boat.

Trim tabs are not normally painted with antifouling paint and are generally cleaned monthly. Your rudder area may need paint. I'd wait untill the next haul out.

Also, make sure your anodes are the correct one's for salt water. I took delivery of a 2006 340 this summer and within 3 weeks of being in the water, mine were totally gone. Searay had the salt water one's on and I am in the great lakes, after the correct anodes were put on, no issues.
