MerCruiser 350 MPI Alpha Bravo 300 HP Fully Dressed Engine (8M0136293)

A fully dressed MerCruiser 350 MPI V8 marine engine rated 300 HP at 5,000 RPM, part number 8M0136293, for Alpha and Bravo sterndrives. It uses multi-port fuel injection with Cool Fuel II on a 100% new Quicksilver cast iron block.

The 350 cubic inch engine has a high-strength steel crankshaft, roller camshaft, 1.5:1 stamped rocker arms and Quicksilver cast iron cylinder heads with Black-X valve technology. Cooling is raw water with warm exhaust manifolds, and the exhaust uses a dry joint. An ECM555 with Engine Guardian manages the engine, which is SmartCraft ready and runs on 87 octane fuel.

Mechanical throttle and shift with a 10-pin harness suit existing controls. It directly replaces 5.0 EFI, 5.0L MPI, 5.7L EFI and 350 MPI Alpha sterndrive models. Installed with an Alpha One (Gen I) drive, it requires Seawater Pump Kit 46-8M0139983 and Serpentine Belt 57-865615Q03, both sold separately.
