ok, heres the deal. I purchased a new hummingbird depth finder. The existing lowarance always reads .5 ft. The installation instructions seem fairly straight forward but the problem lies in the removal of the old one. The boat is a 2001 Mariah 212 and the dash is all molded fiberglass, you cannot even see the back of the existing finder from underneath. From in the bow you can flip up the starboard back rest and see a little of it, but my bifocals don't really do me justice. Regurdless it seems that there are screws from the front but there is no way I want to pry around on plastic trim on the dash of a boat that the company is no longer around. Does any body have any suggestions?
