Seaboard Marine offers fairly reliable shipping services, especially on routes between the US and Latin America. Deliveries are generally on time and coverage is good. However, customer communication can be a bit slow at times. Overall, a solid option. ⭐⭐⭐⭐☆
The aftermarket SMX Cummins parts manufactured by SB marine and the best I've ever used, A huge upgrade to genuine parts in my opinion. I order and engine hose it, saltwater pump and several cooling service kits, all were fantastic and arrive to me in Australia in record time. I will never use genuine parts again where SMX is an option. I even gave them a call before placing the order and the staff were incredibly knowledgeable and helpful. Highly recommend Seaboard marine
My experience with seaboard marine was reliable and efficient. The shipping process was smooth, and my cargo arrived on time and in good condition. their team made international shipping much less stresssful.
SBMAR is super reliable. Their parts team is knowledgeable and fast, They ship quickly, and their customer service (especially Marco) really goes above and beyond
Awsome as always guys, we are a Cummins dealer in the UK and your speed and availabilty of stock is always very helpful in backup when we have a supply chain issue. Great work!!! Thanks
Oh my goodness this was one of my best Marine parts experience ever. I dealt with Marco at Seaboard Marine and if you ever need parts, especially for Cummins engines give these people a try you will not be disappointed. I’m looking forward to getting the alternator and getting my boat back up and running.
Special thanks for Marco and seaboard team for professional job. Parts received other seas in 3 days. Do not hesitate to ask Marko what you need and he will make it for you
Marco and the SB team were awesome with getting my boat up and running. After calling and speaking to them on options, they shipped my heat-x out same day and it arrived on time. Further, the shop I used misplaced an item and SB was kind enough to ship a replacement immediately.
Wonderful customer service!! I was in a bind while cruising and contacted SB Marine to order a urgently needed part. Marco was extremely helpful - quick to respond to my questions and handled everything very professionally, including arranging for overnight shipping!! Greatly appreciate and highly recommend!
Easy to deal with, timely responses, answering my dumb questions and everything else - Marco from SBMar was great to deal with!
I was tasked with ordering and installing a new SMX control system from SBmar by my customer. Ordering and shipping was quick and a breeze! As far as install goes it took some time and a good amount of work but that’s due to the boat manufacturer, the SBmar side of things was great! With the wonderful experience of the tech support that Corey, Alex, and Josh supplied me with I was able to get my customers vessel up and running with little to no issues. These guys over at SBmar really know what they’re doing and I’d highly recommend any of there products, especially anything related to the replacement of any smartcraft/mercury old electronics. I can’t thank them enough, this job wouldn’t have been completed without them!

The whole company is made up by a team of professionals. When it came time to pay, Marco quickly and efficiently got the invoice generated, the payment processed and the parts in the mail. Great customer service and a prime example of how U.S. Manufacturers should do business.
Great company to deal with Marco was helpful and fast delivery
As usual, SBM came to the rescue in stocking a QSC8.3 Aftercooler that was needed ASAP to get a customer’s boat back in operation. Marco in the Parts department was very knowledgeable and helpful in confirming that the correct part number was in stock and available for shipment. Although the call was made late in the afternoon, Marco expedited the pre-service of the component and was able to get it shipped the next day. Fair pricing, deep expertise and outstanding customer focus is what makes SBM the company to use for all Cummins marine products. Well done SBM and Marco! 👍👍👍🙏🙏🙏
If you want a company 2nd to none coupled with the most competent employees look no further! Thank you Justin and Alex for your assistance and support, you have helped me save MUCHO bucks by doing things myself- along with your brilliance!
I placed an order for a new hose kit and clamps for my Cummins QSB 5.98 HO engine...two days before Seaboard Marine's annual sale began which included a 10% discount on these items. Argh. I wrote to Seaboard and asked if they would extend the sale discount to me since I placed the order so close to the sale period. They did! No questions asked. I was more than impressed with their generosity. This experience stacks on top of many prior orders I've placed with them. They have always been prompt, accurate, and seem to carry a great inventory of parts, making for quick order fulfillment. I'll continue to do business with them and recommend them highly.
I was impressed with the same-day order processing and the helpful courtesy call from sales to double-check my product needs
