Seaboard Marine stocks alternators for all of Cummins marine engine models. Cummins has supplied their engines with many styles of alternators over the years, but the most common are the Delco Remy 15SI, 19SI, 21SI, 22SI, 24SI & 28SI models.

We offer new alternators modeled after the world-class Delco Remy units with higher amperages & upgraded regulators along with our expertise and guidance to allow “Plug & Play” replacement – Our price for direct replacement or UPGRADED units cannot be touched when you want a hassle-free installation and a quality unit.

We also offer “kits” to upgrade from the very early Bosch K1, Prestolite / Motorola, and early Delco units that were used on the earliest Cummins B-Series engines. We speak the language of alternators well, and know the Cummins engines and DC power distribution on boats like no other!
