Go ahead and Google "Propane Lockers". 1980's boats did not come equipped for propane so question the origin, safety and quality of the stove you may be getting. An adequate stove should have "thermocouple" burner switches; they will shut off gas supply if the burner's flame is blown out. In today's standards a safe propane installation requires, remote solenoid switches, gas sniffers, vented to the outside propane tank lockers, unitary run of gas lines with seals along the run for traversed compartments. Back in the day we used simple stoves with a propane tank that sat on deck next to the mast, The obligatory safety features were our nose and a total attention to the stove while in operation and the opening and closing of the tank valve just before and immediately after every use. Today those precautions are provided for you by the equipment requirements which may cost $1,000 to $2,000. The stoves of the day were pressurized alcohol stoves which brought concerns with flareups. Now they have excellent denatured alcohol stoves which are non-pressurized. Google the Origo models, they are not cheap but their cost and installation is a bargain when compared to a propane installation. Start with your needs, are you going to cook a lot or just reheat? With experienced we learned to cook at home, freeze and just reheat at the boat.
