Recipe for Near Disaster

Take one 25 year old Gheenoe that's been sitting peacefully at my sister's house at Lake Lure in Western North Carolina for years. Add a new $850 trailer and a slightly used 2007 15hp Suzuki motor bought on eBay for close to $2000, which is 10hp more than the boat is rated for. Drag all this down to St. Augustine, Florida because I have a place down there now and a burning desire to go fishing which I have rarely done and done only once in salt water. Add my Dad to the front end of this nautical missile and me at the helm, and drop her in the creek and head out to the Intracoastal Waterway. What do you get? My Dad with white knuckles and me with a curiosity about what that popping sound is at the stern of this monstrous little torpedo. When, on the return trip from the ICW, where, by the way, the wake from a passing yacht convinced me that leaving the creek and venturing out into the ICW was probably not a wise decision, I got to thinking that if the transom of this boat were to crack off from the sheer weight and propulsion of the motor that the boat would probably fill up with water pretty quickly. I decided at that point that a bigger boat was in my future if I was going to fulfill my dream of catching all those "doormat" sized flounder that my family and I are so fond of. Do ya'll know anybody that wants to buy her?
