Removed a Fischer Panda 3.9 to make room for a. larger unit, worked perfectly before removal. I have no history on the unit as it was in the boat when I bought it recently. Started right up and could barely hear it but we need a bigger unit to run the Seakeeper so it has to go. Located in Santa Cruz, CA . Make me an offer. Tried uploading photos but was unable due to file size. I'm technically challenged.
