Two steps: you need to make a locker that drains overboard (the West Marine Advisor online and in the catalogs has a very good description of the requirements), or go external rail mount - many use starboard for "holders", and you need to change your burners, perhaps the oven, too - I forget. Call Dennis at Seaward in California and he knows exactly what to do - be prepared with the serial number of your stove from inside the opening top cover.
