I'm in the process of buying a 1981 S2 11.0 Center Cockpit. I am looking for anyone who owns one currently or in the past or who may actually have material on the boat such as manual or true spec sheet. I have sale brochures for days, but internetresearch on S2 manuals for this model is very limited and all most non-existent. I have found manuals for the engine. Any help would be greatly appreciated.
