NO! Its not the usual type of "Swingers".
This is a boatracing class in Finland!
When I and my team was over in Finland this summer for the Nordic Championship, they raced this class before our race.
Its a sort of one type class. Everyone has a "Marino Swing" boat. A local old boat that is very succesfull in Finland.
Maximum cc of the engine is 449. Tune it and fix it how you want, just keep it 449cc
top speed is around 46mph and the engine have around 40 BHP.
Of course I took some pics of the race and filmed abit as well
