      Mercruiser Engine Parts

      For fishing, boating, boat racing, and watersport activities, the MerCruiser sterndrive provides ample power for every boating activity. Maintaining your MerCruiser sterndrive well, however, is key to its performance and your continued boating pleasure. Keeping your MerCruiser sterndrive trouble free is easy when you know where to go for the right replacement MerCruiser parts. Wholesale Marine carries everything marine mechanics require to perform routine maintenance or make simple or complex repairs to almost any MerCruiser sterndrive model. For boat owners and boat mechanics, when you need replacement MerCruiser engine parts, come to us!

      Since the 1950s, the MerCruiser by Mercury has been one of the most popular sterndrive manufacturers. Known for their performance and reliability, it is easy to take your MerCruiser sterndrive, made by one of the industry leaders, for granted. Here are some basics to understand, even if you do not plan on performing maintenance and/or repairs yourself.

      Key Mercruiser Parts That Require Routine Maintenance

      Routine maintenance is key to extending the life of your sterndrive. It’s best to refer to your MerCruiser Service Manual for guidance. We discourage boat owners from performing the actual work themselves; this is not a job for amateurs. But troubleshooting after every voyage will help to find possible problems before these become major expenses.

      Most sterndrive engines are constructed from parts that include metal alloys. These can corrode through a process called galvanization. Regardless of its name, corrosion must be avoided. One way to accomplish this is to apply a superior antifouling product. Wholesale Marine stocks a full line of these products and we’ll be glad to advise you on the product that is best for your sterndrive.

      Drives have bearings that permit rotations. The drives are usually made from a steel/aluminum alloy that requires frequent lubrication to prevent corrosion. We recommend Mercury 2-4-C Marine Lubricant with Teflon for superior protection. Gear oil must also be checked regularly. Located just below the round gear housing you can access it by using a slotted screwdriver. Back out the plug until it loosens and some oil starts to run out. Translucent = good; milky means water has compromised your oil. Then it is time to have your seals replaced.

      Next, check your propeller shafts by rotating them. If these are not rotating perfectly straight, a bent shaft which requires immediate replacement could be the culprit. Lastly, check the bellows hoses for the drive shaft and shifting controls. These must have water-tight seals as well. Raise the drive and inspect them looking for signs of cracking and fouling. Rout any sign of algae or barnacles which can easily destroy the bellows. Check their clamps for rust and replace if necessary.
