engine was a massive 5190 cid (85.0-liter) four-cylinder that produced 350 bhp (0.07 bhp/cid). It allowed the motor boat Le Dubonnet piloted by Emile Dubonnet to set a new world's speed record on water, reaching on the lake at Juvisy, near Paris, France. An example of modern multi-valve engines for small boats is the Volvo Penta IPS Series. These joystick-operated seawater-cooled inboard diesel engines use combined charging (turbo and supercharger, except IPS450) with aftercooler, common rail fuel injection and DOHCs with hydraulic 4-valve technology. Propshaft power ranges from (highest efficiency 59.7 kW/liter for IPS400 3.7-liter straight-4 diesel). Multiple units can be combined.
