I will look for a picture online. The boat has a through-the-hull motor mount. The motor is a Honda 2 HP air cooled four stroke. it sits to the port side of the tiller, in the port half of the seat which would otherwise go across the cockpit under the tiller. The ones I have sailed on in the past do not sail with the motor attached. Without the motor there, there is a hole(about 12" x 12") that looks directly into the water. So a plug goes in the hole (usually of fiberglass, maybe always of fiberglass), that fits in and has a pin that holds it in place. So the cockpit seat goes all the way across--with a slight lip where the plug is. I have a sense it was original equipment, but am not sure.
