8.2 MAG H.O. ECT
Simple. Easy. Powerful.
Built for ease – from maintenance to maneuvering.
- Durable: A high-displacement footprint allows the V-8s to work smarter – not harder –with lower revs 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 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. SmartCraft® Digital Throttle & Shift provides silky-smooth operation.
- 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!
- 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 with the Bravo® drive.
