And the latest engines being offered by GM Powertrain, including its LV1 4.3-liter V6 and L83 5.3-liter V8, feature all of those technologies. A marine engine, by comparison, has to cruise at perhaps 75 percent throttle.” While Foulkes recognizes the value of technologies like variable valve timing, all-alloy construction and direct fuel injection in the automotive arena, he feels that due to cost and complexity, those features are of little advantage in a boat. “When you think about driving your car or truck, you spend most of the time at 10 to 15 percent throttle. “New automobile engines are designed to work best at a very light load,” said Foulkes. Today fuel mileage is the primary focus of auto engine development, according to Foulkes (who is a former Ford powertrain chief engineer), even for the light trucks typically powered by the engines sourced for marine duty. For generations the marine industry has relied on “marizined” versions of automobile engines, primarily sourced from GM Powertrain and Ford, for its gas inboard and sterndrive engines. At the recent media introduction of the MerCruiser 6.2L MPI, Foulkes repeated the assertion he made last year when Mercury launched the 4.5L engine-that Mercury sees little benefit for the marine industry in many current and emerging automotive engine designs. Note the deep tray around the oil filter to contain drips when changing the filter. Delivery throughout NZ Taupo’s only Mercruiser & Mercury outboard, Honda, Volvo Penta, Yanmar and Parsun service & sales dealer with 40 years Mercury service experience.A marine-specific design places all common service points on the front of the MerCruiser 6.2L. Lakeland Marine Services is NZ’s only Bayliner specialist dealer. * ENGINE AND STERN DRIVE PACKAGE (ALPHA) RRP: $29,200 NZD – Additional cost for Bravo Drive The result is increased throttle response and a sporty feel. The 4.5L comes standard with Adaptive Speed Control, which automatically maintains engine rpm regardless of load or water conditions. For maximum defense against saltwater effects, the SeaCore® industrial hardcoat anodising system and closed-cooling circuit is available. Protection, Corrosion The MercFusion Paint System creates an outer seal against the elements, while MerCathode® provides automatic protection against galvanic corrosion. Resulting in an exceptional driving experience. The 4.5L’s newly designed rear-facing throttle body, anti-whistle throttle plate, engine cover and mounts, lightweight flywheel, fuel-supply module, and structural oil pan all work together to deliver a superior idle, smoothness and low vibration. Thanks to its new, long-runner scroll intake manifold which draws in more air and converts it into additional torque, the 4.5L delivers a ground-breaking power-to-weight ratio and gives you V-8 power in a V-6 package. Designing a V-6 block solely for marine use allows Mercury to build the 4.5L with the ultimate protection system, using cast-iron componentry where the engine intersects with seawater, and using corrosion-resistant aluminium and composites everywhere else.
