As Caterpillar’s newly appointed Global Pleasure Craft Manager Jeff Greener explains, the new 3500C engines, the latest in a family which has been the driving force behind industries such as fishing, offshore supply, ferries, tugboats, crew and supply boats, short sea cargo vessels and custom (mega) yachts around the world for more than a decade, are now reaching the point where they are viable contenders for larger planing hull yachts above 120’ as well as their more traditional displacement and semi-displacement applications. “The new 3500C-HD family presents opportunities for shipyards and yacht-builders to achieve higher engine performance with lower costs, They provide more power for a variety of vessels and configurations, delivering typically 20% more power with no additional weight or engine footprint for displacement and semi-displacement hulls. With a twin engine installation now offering up to 6870 mhp for twin engine applications at our highest rating, these engines can also offer top quality planing hull propulsion power for larger yachts. “These ‘D’ rated engines also achieve exceptional reserve power for excellent acceleration without the complexity of sequential turbocharging.” Table 1.

The Cat 3500 engine family has achieved sales of more than 12,000 in the marine market since its introduction in 1980 making it the most popular engine in its power range in the world. It has a reputation, working in some of the most testing and arduous environments and applications on the planet, for delivering market leading performance and economy, while outstanding levels of reliability and ease of installation and maintenance have been a boon to operators and shipyards alike for many years. The new engines are scheduled for production in June 2005 at Caterpillar’s Large Engine Center (LEC) in Lafayette, Ind. ACERT Technology Leads to Increased Ratings Caterpillar developed the new engine ratings through a range of engine modifications, including electronic control, or “software,” changes, as well as new components and “hardware” developments. Caterpillar’s ACERT Technology provides higher ratings with lower peak cylinder pressures, exhaust temperatures and smoke than current ratings (see release ref MPC070105). In addition, new hardware technology used on the engines includes an optimized injector spray angle and combustion crater, modular pulse exhaust manifold, high-efficiency turbochargers, A3 ECM (Electronic Control Module), drilled connecting rod, higher flow piston cooling jets and larger oil cooler. 3500C-HD Features • Cat engine mounted plate type heat exchanger with integrated fuel cooler • Rigid wiring harness providing more robust wiring system • Power take-offs for auxiliary drives such as compressors and hydraulic drives • Remote mounted Cat pilot house panels with integrated displays and controls • User configurable Marine Power Display (MPD) • Separate circuit and combined circuit cooling options with high capacity pumps • A3 ECM, the most advanced engine control module for Cat marine engines 3
