Did you know? There are two types of boat parts to choose from: Original Equipment Manufacturer (OEM) or aftermarket. If you boat is new, or has seen only a couple seasons of use, your OEM will be the preferred way to go. For your convenience, OC Boat Supplies keeps a huge inventory of these replacement marine engine parts on hand. Yet OEM parts may be too expensive for some of us. And for older, well-preserved boats, OEM parts may no longer be available. Should you opt for aftermarket, no worries, OC Boat Supplies has your back. We stand by the products that we sell since many of today’s aftermarket parts undergo the same quality testing as OEM parts. The only difference is price as aftermarket parts cost far less than their OEM cousins.
