When it comes to boat engines, the name MerCruiser stands out as one of the finest and most respected in the industry. Unlike competitors that take automobile engines and marinize them, MerCruiser inboard and outboard engines are designed from the ground up to serve as boat engines, ensuring that there is no compromise when it comes to design and construction. At NuWave Marine, we pride ourselves on our ability to help customers find any MerCruiser part they need so that they can get the most out of their boating experience.

MerCruiser offers inboard and outboard engines for almost every kind of recreational boat that exists. At NuWave Marine, we’re dedicated to supporting our customers who use MerCruiser engines on their boats or frequently work on them by providing OEM-certified parts. Whether you need a new transom assembly or parts for your MerCruiser exhaust, we can provide the replacement components you need. If you’re looking for MerCruiser repower engines, we offer a range of options to help you find the perfect new powerplant for your boat.

MerCruiser Inboard & Outboard Engine Parts

Our comprehensive inventory of MerCruiser engine parts ensures that you can always find the components and accessories that you need for your boat’s inboard or outboard MerCruiser motor.

Our outdrive parts and tools are OEM-certified, ensuring you can always be sure of compatibility whenever you make repairs.

Your Trusted Dealer for MerCruiser Engines and Parts

While there are plenty of websites and stores selling boat parts out there, few have the same depth of experience and track record for customer satisfaction as NuWave Marine. For over forty years, we’ve sold inboard and outboard Mercruiser engines and parts both online and in-person, providing high-quality service to both professional mechanics and DIYers at home. No matter what you need, our expert staff is eager to answer any questions you have and help you find solutions to your boat’s mechanical problems, so don’t hesitate to reach out to our team today!
