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.

Free Ground Shipping

All orders over $499 are eligible for free ground shipping. This option will be presented to you at checkout once you are logged in. Orders under $499 will be charged a flat rate of $9.99 regardless of weight. We use Fedex, UPS, and USPS to ship our deliveries. *Not Available to AK, PR or HI **See exclusions below

$29.99 Overnight Shipping:

Most Marine Electronics orders are eligible for $29.99 Overnight Shipping. Orders must be placed by 2PM EST. This does not include Saturday deliveries. This option is only available on phone orders. If we are unable to provide overnight delivery due to inventory allocation you will be given alternatives. *Not available to AK or HI **See exclusions below

$14.99 Two Day Shipping:

Most orders are eligible for $14.99 Two Day Shipping. Orders must be placed by 2PM EST. This will not include Saturday deliveries. This option is only available on phone orders and is not available with special orders, price matches or back ordered items. If we are unable to provide two day delivery due to inventory allocation you will be given alternatives. *Not available to AK or HI **See exclusions below.

**Exclusions:

**This offer does not apply to some oversized or hazmat items like Liferafts, generators, outboards and outriggers or non-electronic products like running lights, deck hardware, apparel, etc.

**This offer can't be used in conjunction with other discounts. If you are receiving another discount from us such as a "Price Match" standard shipping rates will apply.

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.
