Worth knowing
Ski Supreme; cover, cost and conditions
Ski Supreme is a Californian name that appeared in the late seventies under the umbrella of Supreme Industries Incorporated. The idea was clear from the start: tow boats for water skiing with an inboard engine and later V-drive, built for tournaments where a steady pull and a flat wake matter most. According to an American boat directory the boats ran from 19 to 21 feet. The brand later changed hands several times. Genmar Industries took over the Ski Supreme name in 1989, and from 1994 to 2009 Fineline built Supreme boats in Merced, California, alongside its sister brand Centurion. Today a family business in California carries the Supreme name forward.
Our model records list a single design that carries the brand name itself: the Ski Supreme, a motorboat of 5.8 metres built from 1976 to 1983. That is just over 19 feet, the lower end of the size range given for the marque. Nothing reaches into the most recent build years, so every boat listed is more than forty years old. These are the classic inboard tournament ski boats of their era, with the engine in the middle of the hull and a straight shaft running to the propeller underneath. Later generations with V-drive and wakeboard towers only arrived after the period our records span for this model.
An inboard ski boat from the late seventies needs a buyer who looks underneath. Check the engine mounts and stringers, since decades of hard acceleration with a skier on the rope put a lot of load into the structure. The shaft, strut, cutless bearing and propeller should run true, and the rudder should move without play. Original upholstery and gauges add character but are often tired; replacing them is common. Many of these boats spent their lives on fresh water lakes and were kept on trailers, which helps the hull. A boat with a documented engine rebuild and a sound floor is a good basis for many more summers.
