Known problems for this model
-
Cramped engine compartment engine
Twin V-drive gas engines sit close together under a power hatch, making plugs, raw-water pumps, strainers, starters and the generator hard to reach; V-drive packing service may require pulling exhaust risers.hmy.com · boatered.com
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.powerandmotoryacht.com
-
Rough running and won't rev under load fuel
Common troubleshooting threads trace this to fuel delivery (filters, pump, carburetor) or ignition timing problems.justanswer.com · youtube.com
