Marine Engine Pistons

The function of pistons in both automotive and marine internal combustion engines is virtually the same – they transform the energy of expanding gases into mechanical motion. However, the design of pistons and the technology used for their manufacture often differ depending on the motor's type and model. For instance, the companies producing two-stroke engines typically install two-ring pistons, or even the ones with a single ring in some smaller motors. Anyway, when it's time to replace the pistons and/or rings in your boat's motor, it makes sense to get those coming from reputable brands and designed specifically for this engine.

A large assortment of top-notch marine engine pistons, rings, and related products is available on our virtual shelves. Providing maximum possible ring seal and minimizing the blow-by effect, new pistons will help you restore the initial power of your vessel or even increase it. Made with the use of modern technologies, many of our pistons feature special coatings to reduce friction and wear, while their designs contribute to horsepower increase. You can choose among piston kits and rings made for motors by Suzuki, MerCruiser, Yamaha, Johnson / Evinrude, and other reputable companies.
