BREAKING NEWS FROM Mercury Racing:
NEW 250R & 300R FOUR-STROKE V-8 OUTBOARDS!

"Designed, developed and manufactured in-house, the naturally aspirated, 4.6L V-8 four-stroke engines share Mercury Racing’s venerable Quad Cam Four Valve (QC4) sterndrive DNA – complete with aluminum four-valve cylinder heads and dual overhead camshaft (DOHC) valve trains. The four valve heads and DOHC valve trains are integrated with Mercury’s proprietary V-8 cylinder block, packed with high performance hardware. The new platform replaces the two-stroke V-6 250XS and 300XS models..."

Mannerfelt Designs the HYPERCAT
Mannerfelt Designs the HYPERCAT

An important video for those following XCat racing. Swecat Racing has commissioned Ocke Mannerfelt of Mannerfelt Design Team (Swedish) to design the next XCat series race boats. Designed to be powered by 400ROS on the race circuit and equally at home with 400R motors when in pleasure mode. Stay tuned for more of this exciting development. If you don't have time to watch this 26 mins video, you can simply read the notes I took from the video “form follows function” “organic design” “sleek in the back” “rounded front” “linkage to old race cars from the 40’s and 50’s” “cockpit is interchangeable to pleasure cockpit by simply removing the hatch” “the black area above the glass is an aftermarket piece to allow the removal of the hatch” “the race boat is the same boat as the pleasure boat” “Ocke’s son, Ted has a car design background and he used his car design background to design the HyperCat” “the deck area around the front sponson has a ‘crease’ both for aerodynamic design and for walking safely on the bow and not slip” “steps between the head rests aid the person when walking to the back of the cat… safely” “the deck has winglets, like the tip of the airplane, built for speed and stability when cruising/racing at speed” “beautiful shapes make for better performance boats” “the engine shield also acts as a splash guard against rushing water so as not to destroy the engines when big water hits the motors” “the hull is very efficient, at 75MPH she’ll burn 3MPG with Verado motors" “the challenge to us when designing the boat is that we have to ‘fit’ the boat to an existing tall power plant” “the motors are tall so we have to design to reduce that drag…the engine shield reduces the aerodynamic drag by 25%" “with this deign, we can recycle old race boats to pleasure boats by simply removing the top hatch” “the first pleasure boat will be built in the first quarter
