I contacted Goetz (Trol-Eze) yesterday in Idaho. Apparently they are popular around the USA , but off the "top of his head" he couldn't think of any specific dealers in W. Washington other than Arima.. but said there are some, just couldn't think of them. He said lots of marinas carry them but won't sell over the counter because they want to do the installation. Shop foreman, John, is sending literature, and said people can deal directly with him, sidestepping dealers. PRICE $650 + or - and u do installation...
