In the world of speed boat racing, this class has become a very strong influence in Eastern Europe and in Central England. In the last years, there were average 8 to 12 racers from Germany to venture the waters of the F R1000 class. In Order to keep this class of racing from dying out, it has been put into what was called since the early nineties the Historical Class HR-1000. This eliminated for the moment the expensive upgrades in engines and boat design, for instance special safety cockpits. From 2002 this class is called Formula R1000. Only naturally aspirated, reciprocating, carburetted boat, motorcycle or motor car engines, of a model and type manufactured at least ten years ago, are permitted. Also engines which are originally manufactured with fuel injection are allowed provided they are re-worked to use carburettors only. The drive line between engine and propeller to be basically straight (no Z drives). A gearbox may be attached at the motor however it is forbidden to change the gears while racing (rule 518.01 UIM). Favorite engines are for instance Yamaha, Honda and Rotax. The 2-stroke Tact Wartburg engine is not longer in use. The engines can go up to 140 to 150 horsepower and reach speeds up to 160 kmph (100 mph).
