INBOARD PERFORMANCE SYSTEM A revolutionary marine propulsion system Buyers of sports cruisers, flybridge yachts, sport fishing boats, and other craft with traditional inboard propul- sion have an increasing demand for reduced emissions - in particular the carbon footprint - but also for im- proved handling, enhanced onboard comfort, higher speed, and fuel sav- The Volvo Penta IPS system is the answer, combining all the above with driving pleasure, reliability and outstanding environmental proper- The successful Volvo Penta IPS propulsion system is now available in a larger version matched to our new 11 liter engine. This means that we are reinforcing the IPS range to a performance power level equal to 800 and 900 hp, suitable for approx. 48 up to 55+ feet planing hulls in twin installation. In triple and quad applications the system reaches a power level up to 3,600 hp, appli- cable for approx. 80-90 feet range. The new larger Volvo Penta IPS version, having concept, technology and software in common with its smaller sibling, is setting a new standard in: - Improved efficiency, higher top speed, reduced fuel consumption/extended range, and great acceleration - Low-speed maneuvering is easier than ever before, and at high speed handling it offers safe and predictable - Much improved overall environmental care - Onboard comfort is greatly enhanced thanks to much lower levels of sound, vibrations and exhaust fumes - Installation is greatly simplified - More space available for accommodation - Improved safety and redundancy - Ease of service, the complete system from helm to pro- peller cone supported by one supplier All this is combined with the usual benefits of a tradi- tional inboard such as a robust, high strength construc- tion, excellent corrosion resistance and the propellers A conventional inclined shaft system starts to lose efficiency at speeds acc. to the lower curve in the diagram below. Low efficiency means less power transmitted to the water, and that more power is needed to increase speed, which, in turn, results in increased fuel consumption, reduced cruising range, and more exhaust emissions. The Volvo Penta IPS offers a revolutionary solution to this, with outstanding effi- ciency over the whole speed range 28-40 knots (see the upper curve in the diagram). Volvo Penta IPS has as much as 35% better efficiency at 38 knots. This means that engine power is transmitted much more efficiently into the water resulting in: - Increased speed - Reduced fuel consumption - Faster acceleration - Much less emissions per nautical mile Propulsion efficiency

As an example, the required power at various speeds for a 55 foot, twin installation, 20 ton sports cruiser, the diagram shows the difference in engine power for the two systems. In general terms, if the top speed is above 35 knots, the performance advantage is as much as 35% (equal to ap- while below 35 knots the efficiency with the Volvo vironmental impact will be correspondingly reduced. Because of this superior efficiency, the product designa- tions 800/900 communicate engine power required for a conventional shaft installation to reach a comparable perfor- mance level.

- The propellers are producing horizontal thrust and working in undisturbed water with no cavitation. - There is an increased number of propeller blades (7) with smaller diameter to distribute the forces in combi- nation with good tip clearance to the hull. This means that the pressure pulses created by the propellers have very little effect on the hull. - Exhaust fumes are minimized. First of all, the new en- gines have very low exhaust emissions, and secondly, the exhausts are emitted into the prop wash and car- ried well behind the boat.
