About Turn-Key MPI Engines

Electronic Fuel Injection (EFI), has come a long way on marine engines in the past 15+ years. Reliability and simplicity separates the current line of fuel injected marine engines from those of yesterday. Imagine hoping in your boat on a brisk morning, turning the key and having the engine start as easily and reliably as starting your car. Better yet, consider taking your boat to a higher elevation in the mountains without having to adjust and replace the carburetor jets.

With the current generation of tried, tested and proven EFI engines, specifically Multi Port Injection (MPI), you can do away with the adjusting, tinkering, and tweaking of the carburetor and distributor system. The current generation of 4.3L, 5.0L, 5.7L, 6.0L, 8.1L and 8.2L marine engines are all offered with the MPI option for only a fraction more than the carbureted version.

There are many benefits to the current MPI marine engine lineup: 15-30% better fuel economy, consistent and even throttle response, 4th or 5th generation Electronic Control Module (ECM) that prevents the engine from dangerously overheating, added horsepower and torque when compared to the equivalent carbureted engine, programmed rev limiter to prevent engine damage, knock sensor that automatically adjusts to poor or lower octane gas, automatic elevation compensation, and even distributorless ignition in some cases, such as with the 6.0L and 8.1L MPI engines.

Call Michigan Motorz today at 248-524-9600 to determine which MPI fuel injected marine engine is ideally suited for your boat.
