      Mercruiser Engine Parts

      Whether you are fishing, boating, boat racing, and watersport activities, the MerCruiser sterndrive provides power to spare for every boating activity. MerCruiser sterndrive maintenance is important to optimal performance and successful boating every season. Keeping your MerCruiser sterndrive trouble-free is simple when you have the right resource for the right replacement MerCruiser parts. Wholesale Marine has everything you need to perform ongoing maintenance or repair your MerCruiser sterndrive parts. If you’re a boat owner or boat mechanic, we’ve got you covered with all the replacement MerCruiser engine parts you need!

      Since the 1950s, one of the most popular sterndrive manufacturers has been the MerCruiser by Mercury. This brand has been renowned for products that deliver high performance and dependability. We offer some simple basics even if you are not looking to perform your own maintenance or repair jobs.

      Important Mercruiser Parts That Require Maintenance

      Ongoing maintenance is essential to extending the service life of your boat’s sterndrive. It’s recommended that you consult your MerCruiser Service Manual before making any repairs. We don’t advise that boat owners perform DIY work themselves, as it’s not a job for novices. However, some simple troubleshooting after a long boating trip will assist in uncovering potential problems before they turn into expensive repairs.

      Many sterndrive engines are made from parts designed from metal alloys. These can corrode over time through a process called galvanization. Regardless of what you name it, corrosion is enemy #1 for your Mercury sterndrive. One way to control corrosion is to apply a superior antifouling product. Wholesale Marine carries a full line of these products and we will be glad to assist you on the product that is best for your sterndrive.

      Drives have built-in bearings that permit rotation. These drives are constructed from steel/aluminum alloy that requires frequent lubrication to guard against corrosion. A great choice is the Mercury 2-4-C Marine Lubricant with Teflon which offers superior antifouling protection. Gear oil should be checked regularly as part of your maintenance regimen. Located just below the round gear housing, it can be accessed by using a slotted screwdriver. Back out the plug until it loosens and some oil starts to run out. Translucent means the oil is still good; milky means water has compromised your oil. This is an indicator that the seals should be replaced.

      The next step is to check your propeller shafts by rotating them. If they’re not rotating perfectly straight, a bent shaft that requires replacement is the likely culprit. Finally, have a look at the bellows hoses for the driveshaft and shifting controls, which must-have water-tight seals as well. Raise the drive and properly inspect for any signs of cracking and fouling. Rout any presence of algae or barnacles, as they can quickly destroy your bellows. Also, check the clamps for any sign of rust and replace them if required.
