Engines & parts

MerCruiser 7.4 (454) V8 gas parts: good

Factory standard engine — you entered “MerCruiser 7.4L MPI V-drive”

GM big-block base; Marine Engine Depot and others sell 7.4 L engines and parts, and cast-iron riser kits run a few hundred dollars. Manifold and riser replacement is the main recurring expense.

Common problems (2)
  • Manifold and riser corrosion exhaust
    As with other gas marine V8s, internally rusted manifolds and risers can let water into the engine; periodic replacement is standard practice.

  • Rough running and won't rev under load fuel
    Common troubleshooting threads trace this to fuel delivery (filters, pump, carburetor) or ignition timing problems.
