7.4L (454 ci) Marine Engine – SILVER Package

GM Marine has been leading the marine engine industry for years. GM Marine’s marine engines contain the same advanced technology and as GM’s automobiles. The GM Marine base marine engines that Michigan Motorz provides are the same marine engines that other leading manufacturers buy directly from GM Marine.

This BRAND NEW 7.4L (454 ci) Vortec SILVER package is great for those that need a little more than just a base engine or long block, but still don't quite need a complete engine package. This package will fit, bolt in, and work in nearly all 7.4L (454 ci) marine applications from 1976-2001 with no modifications. If you have an existing Mark 4, Gen 5 or Gen 6 7.4L engine from MerCruiser, Volvo Penta, OMC, or inboard application, then this 7.4L Vortec engine package will work in your application. This 7.4L SILVER package is rated at 330 hp @ 4600 RPM at the crank and comes with the following components:

  • 7.4L (454 ci) Vortec marine engine - Standard rotation, cast iron block, teflon coated pistons, high flow oval port 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) used this Gen 6 7.4L Vortec engine from 1996-2000.
  • Cast iron intake manifold - Made for marine applications. Low-rise, 4 barrel intake commonly used in standard horsepower marine engine applications by MerCruiser, Crusader, OMC, etc. This manifold is made for fresh water and the harshest salt water environments.
  • Edelbrock marine carburetor - 4 barrel with electric choke, spread bore, 650 cfm, 30cc accelerator pump, single fuel inlet, vacuum secondaries, "J" tubes, etc (U.S. Coast Guard Approved), one-piece flexable fuel line, flame arrestor with breather tube and PCV hook-up.
  • Electric fuel pump kit with fuel/water seperator - a low pressure 4-7 PSI electric fuel pump (U.S. Coast Guard Approved), delivers the right amount of fuel to the carburetor but it first must pass through the fuel/water seperator to protect vital engine components from raw water. Includes brackets 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 - bi-directional circulation pump, 14" I/O flywheel, harmonic balancer, 8-quart marine oil pan (approx 9 quarts of oil required with oil filter), side-mounted dipstick and tube, EZ oil drain kit, lifting eyes, one-year manufacturer's warranty, and complete installation guide and operation manual.

  • INBOARD ENGINE OPTION - ADD $200
    - Inboard 14" flywheel
    - Inboard dipstick & tube assembly
    - Wedge plate, allows carburetor to sit level on tilted engine installations.
