Same Day Shipping

We pride ourselves in accurate inventory reporting and efficiency. Most "in stock" orders placed before 2:00 PM Eastern Time will ship out the same day. You can view typical transit times at the Map below. While our site only shows our inventory on hand, typically we can have just about anything you need drop shipped if needed, so if you do not see something in stock please call us. We normally ship from MD which is 1-2 days from the NE and Mid-Atlantic, 3 Days from FL and Great Lakes, 4 Days from the Gulf and 5 days to the West Coast. If you ask, we may be able to drop ship your order from a warehouse closer to you, which may get the transit time down to 2 days or less.

BOE Marine has built our reputation on the ability to ship orders on the same day they are placed, and in many cases you will literally have your order the next day. If there is any problem we will notify you. If you absolutely need your order by the next day, including Saturdays we suggest you place your order over the phone and confirm availability.

Please Read: If you choose the wrong shipping format at checkout, such as choosing Free Ground Shipping if you live in Alaska, we will apply the correct shipping format and cost based on the policies above. If you have any questions about shipping please ask before checking out.

Busbars, Connectors & Insulators

So you have spent so many resources to seal your electrical systems at the vessel just to leave the job incomplete. Well, if you have traditional marine busbars on your vessels, then you have done just the same. With multiple individual connections, the old bus bars are more vulnerable to failure. Also the exposed copper plates have thin to no plating at all! So what do you do then?

BOE Marine is there to the rescue! We are an established online store dealing in a multitude of marine busbar. The innovatively designed DC and ground bus bar listed here encapsulates a conductive copper plate, only exposing the stainless steel studs to connect to the battery.

In marine industry, the bilge environment is always moist. Even when it looks dry, there’s moisture in the air. So you need bus bars with upgraded, sealed connections to blowers and pumps. No more exposed connections on the bus bar when you can buy safe and advanced marine bus bar here!

We all know, the nuts and bolts of any electrical system on the vessel is the connector that keeps the current flowing. At BOE Marine, you can choose from a wide range of smart marine ground bus bars, DC bus bars, negative bus bars, and more options to reduce heat and enhance efficiency in your vessel’s electrical system!
