Mercury MerCruiser's next gen Big Block out soon
Race-based 8.2-litre engine will be available in catalyst and non-catalyst versions
Mercury MerCruiser said its newly developed next generation big-block engine will soon be in Australia, with a catalyst version available out of the US from January 1, 2010, and a non-catalyst version scheduled for release in mid-2010.
The company said the MerCruiser big-block marine engine is an 8.2-litre motor, which it claimed produces more power, has better mid-range acceleration, lower emissions and superior fuel efficiency.
Mercury MerCruiser said its engineers created the new engine, drawing on the expertise of Mercury Racing specialists, with the naturally aspirated big block featuring high-performance aluminium cylinder heads for improved mid-range acceleration and an increase in power.
The company said the 8.2L will deliver 380hp and its HO (high octane) model will deliver 430hp.
Mercury MerCruiser said that thanks to boatbuilder and dealer input, access to the engine’s service points and connections has been significantly improved to simplify installation and maintenance.
"Not only did the team achieve superior performance while adding a catalyst, they maintained fuel efficiency and improved serviceability without adding cost," said Mercury MerCruiser’s project manager, Derric Drake.
In summary, Mercury MerCruiser said the new engine features:
* More power;
* Enhanced mid-range torque;
* World-class, low oil consumption achieved via modern piston and ring pack design;
* Catalyst-equipped for ultra-low exhaust emissions, virtually eliminating exhaust fume odour;
* Runs on 87 octane fuel;
* Higher charging amperage at idle (+15amp);
* Improved installation via simplified access to connections;
* Easier identification of, and access to, service points;
* Low noise and vibration;
* 100 per cent closed cooled from the factory;
* Equipped with Mercury's exclusive, air-actuated seawater drain system; and,
* Traditional MerCruiser factory warranty and service support.
Mercury said the new 8.2L MerCruiser engine will be available in sterndrive and inboard configurations with Base and HO ratings.
The new models, it continued, are completely compatible with the host of MerCruiser options, including Axius, SmartCraft and SeaCore, while Digital Throttle and Shift (DTS) is available on the inboard models.
Mercury said the engine also comes protected by the Guardian system to help prevent catastrophic engine damage.
