Mercury MerCruiser introduces new engine block


Mercury MerCruiser has developed the next generation of big-block marine power, which the company says produces more power and has better mid-range acceleration, lower emissions and superior fuel efficiency.

The new engine features high-performance aluminum cylinder heads that improve mid-range acceleration and increase power. High-octane fuel is not required. The engine runs on 87 octane and achieves low oil consumption, according to the company.

Also, access to service points and connections has been 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 Derric Drake, MerCruiser's program manager on the project, in a statement.

MerCruiser's new big block engine will be available in sterndrive and inboard configurations with Base and HO ratings. The new models are compatible with the host of MerCruiser options, including Axius, SmartCraft, SeaCore and either digital throttle and shift or mechanical throttle and shift on the sterndrive models and DTS on the inboard models. It also comes protected by the Guardian system to help prevent catastrophic engine damage.
