27 HISWA TE WATER MAGAZINE different configurations. The over 12-ton Invictus TT420 had three F350 engines at the transom. With the joystick, this large cabin yacht was simple to maneuver. When accelerating, the three engines made a sound you can tell you’re unleashing a lot of horsepower. It is the sound of pure power. The top with this combination was 40 knots, almost 80 mph. We then tested twin installations on the 5,700-pound, 13-meter Capelli Tempest 42 Cabin RIB and the 6,000-pound Jeanneau Cap Camarat 10.5 motor yacht. Tops of around 42 knots were achieved on both boats, and on the Capelli in particular the acceleration was phenomenal. Within 10 seconds we recorded 30 knots. Phenomenal performance The test run on the 3.8-ton German Strong 31 with twin F350 gave a spectacular picture of the phenomenal performance of the new engines. In 10 seconds we reached 30 knots and there seemed to be no end to the acceleration. Only at 58 knots (107 km/h) did we reach top speed. The Strong is an extremely fast and comfortable yacht with exceptionally good cruising characteristics. And with twin Yamaha F350s, it is probably the fastest yacht in her class. Addition The fuel consumption of the new F350 engines is about the same as that of the F300 engines. With the Helm Master EX system, internal steering and optional coupling to a bow thruster, powerful engines are extra safe and comfortable to operate. The new, featherweight Yamaha F350 engines are therefore an excellent addition to the market. The comprehensive test with video can be found at www.boottesten.nl.
