Big Tiller controls Chaos Cat 12.11.2009 -------------------------------------------------------------------------------- OptiMax 250 Pro XS with Big Tiller 'amazing' Mark Nissen might have been in business for only about a year, but he's already known for creating high performance sports and spear-fishing boats… and his new Chaos Cat 520 is only going to build his reputation. The 5.2m purpose built aluminium catamaran has been tearing through the water off Mission Beach, North Queensland - where Mark is based - powered by an OptiMax 250 Pro XS and controlled by Mercury's unique Big Tiller. 'I've only had the boat in the water for a few hours but everyone who's seen it tells me it's amazing," Mark said. "With the OptiMax 250 Pro XS, the power-to-weight ratio is phenomenal. We've been cruising at 45-50 mph (72-80 km/h) in one-metre seas. "Some might say I've overdone it with a 250 motor but I wanted to see what was possible." By changing his current 23 pitch propeller to a 25 pitch Mercury Laser II prop Mark's confident he can hit 65-70 mph (104 - 112 km/h). "But the fuel economy is amazing as well, which is why I chose this engine in the first place. I've gone for a long run and fuel consumption was less than one litre per nautical mile, and that's into 12-15 knots of wind," Mark said. "The 200 litre tank means we can go 100 miles (160 kilometres) off shore for spear fishing." Big Tiller When he was building the boat, Mark wanted tiller control to allow more room in the craft but he wasn't sure about matching a tiller to an outboard as powerful as the OptiMax 250 Pro XS. "I thought it might be too sensitive, but it's brilliant. The feel and control you get with it is just perfect. Whoever designed it has got it just spot on." The Big Tiller was designed with a ergononomically-friendly, easy to use tiller handle with integrated shift, trim and throttle controls located within easy reach, along with user friendly adjustment knobs which allow for easy modification of the tiller handle angle, throttle handle and valve tension making it very easy to operate. The power steering option (not available on 40-60efi FourStroke models) allows for effortless use for long periods of time without causing fatigue to the operator. It was created specifically for high horsepower Mercury and Mariner outboard engines; 75 to 115hp FourStrokes, 75 to 250hp OptiMax engines, and 135 to 200hp four-cylinder Verado engines with SmartCraft Digital Throttle & Shift (DTS). The Big Tiller has proved very popular in commercial applications across a broad range of outboard sizes, particularly as it allows full engine functionality. DTS power steering is available on all four-cylinder Verado outboards and OptiMax engines with DTS. The system allows for adjustable steering pressure with the touch of a finder and has zero engine feedback through the tiller arm. Sea Patrol Mark's Chaos Cat 520 has already caught the eyes of some great ambassadors - the people behind TV's popular Sea Patrol series. "We went out for two days scouting for new locations and they said some great things," Mark said. Keep an eye out for one of Mark's six metre catamarans in an up coming episode, and they are now looking at using his new creation as well. At the moment, Mark says the Chaos Cat 520 is purely a demonstration model. And it surely is - demonstrating Mark's ability to build a great boat, the power and fuel-efficiency of the OptiMax outboard, and the fantastic control provided by Mercury's unique Big Tiller.

Verado Leaves the Opposition for Dead

Aussie tournament angler, Kris “Pup” Hickson, has yet another way to beat the competition – a top speed of 113 km/h! Kris, from Taree, has a 175 Mercury Verado outboard on the back of his Stratos 285 XL so he’s always been quick, but his dad Jim recently stepped it up. “We were running a 25 pitch prop and kept hitting the rev limiter so we tried a 26 which didn’t make much difference so we put on a 27 and the boat just took off,” Jim said. “I couldn’t believe it. The revs just kept increasing. When I saw that it was almost hitting the limiter with a 27 prop I knew we had a fast motor.” What makes the Verado’s top speed even more impressive is that the boat is in full competition trim. “I think if we took the batteries and all the gear out we could hit 75 miles an hour (121 km/h),” Jim said. “It’s mind blowing. I’m not sure people realise the full potential of these engines. Nobody is running with us anymore in our horsepower range, they turn away. They don’t want to play,” Jim laughed. And the speed’s not down to a special racing prop - Jim’s running a standard Mercury 4-blade Trophy Plus. It’s the icing on the cake for Kris, who’s had a great season so far. He’s concentrating solely on bream this year and has been in the Top 10 in most of the events he’s entered. Economical And to further prove the excellence of Mercury’s Verado technology, the same set up which is providing Kris with such speed is also delivering brilliant fuel economy. “He went cruising on Sydney Harbour recently at about 38 miles an hour (60 km/h) and noticed he was only using five gallons (19 litres) an hour, which is very, very good,” Jim said. “It means that social fishing is now economical, you can afford to go out for a day on the water.”
