Power & Performance.

Durable.

A high-displacement footprint allows the V-8s to work smarter – not harder – with lower max rpm to ensure longer engine life. Engine Guardian is standard and averts potential problems with timely intervention, while the Cool Fuel Module prevents vapor lock.

High-Tech

High Technology.

Long runner intakes pack more air into the chamber, while the advanced MPI system fine-tunes the fuel-to-air mix, producing more power on combustion. High performance aluminum cylinder heads improve mid-range acceleration. Optional SmartCraft® Digital Throttle & Shift provides silky-smooth operation.

Viel Power aus wenig Kraftstoff.

Big Power From Little Gas.

These big blocks put all the power you want on the line when you need it – just the ticket for larger cruisers. The high-output alternator generates 65 percent more power than previous models. Yet the MPI and ECT systems also ensure maximum fuel economy. And these engines take 87-octane gas!

Proteção contra Corrosão.

Corrosion Protection.

The MercFusion Paint System creates an outer seal against the elements, while MerCathode® provides automatic protection against galvanic corrosion. For maximum defense against saltwater effects, the SeaCore® industrial hardcoat anodizing system and closed-cooling circuit is available.
