Michigan Motorz has the 5.7L Vortec Marine Engine - SILVER Package (1967-Current replacement) in stock. This 5.7L SILVER package is rated at 315 hp @ 5000 RPM at the crank and is great for those that need a little more than just a base engine or long block but yet still don't quite need a complete engine package. This silver package will fit, bolt in, and work in nearly all 5.0L and 5.7L marine applications from 1986-Current with no modifications. (Pre-1986 applications will need to update the flywheel and in certain applications, the engine coupler). If you have an existing MerCruiser, Alpha One, Volvo Penta, OMC, or any other outdrive or inboard transmission, NO modifications or gear ratio changes are required when installing this 5.7L Vortec engine package. 12-3/4" or 14" flywheel available. This 5.7L Silver Package comes with the following components:

  • 5.7L Vortec Marine Engine - Cast iron block, teflon coated pistons, high flow Vortec cylinder heads with sintered powered-metal exhaust valve seat inserts, high performance GM marine roller cam shaft with roller valve lifters. These are just a few of the features that add up to more horsepower, greater low end torque, excellent durability, and longevity. All marine engine manufacturers (MerCruiser, Volvo Penta, Marine Power, Indmar, PCM, etc) use this exact 5.7L Vortec engine because of its excellent performance and proven durability. 100% of your wakeboard and ski boats such as Ski Nautique, Malibu, Mastercraft, Tige, Supra, Moomba, etc use this exact 5.7L Vortec engine.
  • Cast-Iron or Aluminum* Hi-Rise Intake Manifold - Michigan Motorz uses this 4 barrel intake manifold for its lightweight durable design and 15hp increase over standard intake manifolds. This manifold is made for fresh water and the harshest salt water environments. (*Additional $200.00 for the aluminum intake manifold option).
  • Edelbrock 1409 marine carburetor - Designed and calibrated for optimum marine performance in small-block V8 engines with a variety of manifolds that include Edelbrock Performer, Performer RPM, RPM Air-Gap, Torker II and other brands of similar design.
  • Electric Fuel Pump Kit - a low pressure 4-7 psi electric fuel pump (U.S. Coast Guard Approved), delivers the right amount of fuel to the carburetor. Also includes fuel pump bracket and oil pressure switch. Loss of oil pressure will automatically shut off the fuel pump thereby preventing gas vapors from accidental ignition and preventing possible damage to the engine.
  • Delco Voyager Ignition Kit - Voyager distributor with Electronic Spark Timing (EST), High energy ignition coil, 8mm marine spark plug wires and spark plugs, shift interrupt wire, timing tool, and other misc wires to easily connect to any existing marine engine wire harness. (U.S. Coast Guard Approved).
  • Also included - 14" I/O flywheel, bi-directional circulation pump; harmonic balancer; 5-quart marine oil pan (5.5 quarts of oil required with oil filter); flame arrestor; high-quality, stainless steel throttle linkage kit; side mounted dip stick and tube; EZ oil drain kit; lifting eyes; one-year manufacturer's warranty, and complete installation guide and operation manual.

    - Inboard 14" flywheel
    - Inboard dipstick & tube assembly
    - Wedge plate with square bore flange, allows carburetor to sit level on tilted engine installations.
