      Mercruiser Electrical System

      The delicate balance of your Mercruiser electrical system is essential to maintain. Each part should be kept in tip top shape to ensure your craft is ready to go when you are. Who wants to dive into the overwhelming task of diagnosing and repairing an electrical system issue? Like many other boaters have already, you can depend on all of the parts we carry here at Wholesale Marine for your Mercruiser electrical system.

      What You Need, When You Need It

      Start your search with our handy Parts Selection Guide located at the top of this page. Simply select “Mercruiser” and then choose from the convenient drop-down menu that lays out each part we carry in a simple to read format. Perhaps an alternator is your need? We carry a wide range of Sierra and Mercury made inventory including alternators, voltage regulators, conversion kits, alternator brackets, and fuse kits, each depicting which part and model number it will replace. All of that power will get you no where without a way to get it started. We have plenty of starters, including diesel, in this one-stop-shop, along with bolts and brush sets. Don’t overheat or overrun your engine. Be sure your coolant, oil pressure, and temperature senders are all running at their best.
