Offshore Marine is a well-stocked provider of marine and boat engine parts at prices that can’t be matched! Our inventory includes both current parts and hard-to-find discontinued parts. We carry a variety of caps, cap assemblies, plug caps, gasket caps, valve caps, oil tank caps, and plug caps for Mercruiser, Yamaha, and Yanmar Marine boat engines. You will not find better prices on boat engine caps anywhere. If you have questions about any of our boat engine parts, email us at info@offshorevi.com. Or ORDER TODAY below and have your engine parts shipped to you right away, with RUSH service available.

Note: Searching by the middle five digits will list all available parts for that group.

Shipping Charges Notice: Shipping to the U.S. only at this time.  The shipping fee associated with this order is estimated based on using the flat rate option provided by the US Post Office, as this works well for the majority of our products. However, if your order contains large items or multiple items that will require multiple boxes, we will contact you with an adjusted shipping total for approval before we ship your order.
