Engine Parts
PowerBoatSupply.com carries all the premium-quality MerCruiser engine parts you need for a full engine overhaul. The MerCruiser I/O and inboard engines generally last longer than their outboard counterparts, but even with their durability, they eventually require service. Find OEM 3.0L MerCruiser engine parts, including alternators, starter motors, and cool fuel kits. Replacement parts also help restore your engine’s ignition and fuel system, whether diesel or gasoline powered.
Typically, inboard engines last up to 1,500 hours, while outboard engines average about 750 hours. Performing an overhaul—taking apart the engine, identifying and replacing worn parts, and cleaning components before reassembly—can improve power and extend service life. Using quality 454 MerCruiser engine parts during an overhaul helps maximize performance and reliability.
