The marine refrigerator was a perfect direct replacement for my old Isothem unit. It arrived well packed, though delivery took slightly longer than expected due to the freight carrier. While it's priced high like most marine equipment, it was still more affordable than other online suppliers. The website was also very helpfulful in matching the exact cutout size I needed.

Hello,
Thank you for your review. All reviews on our Trustpilot profile are from verified customers, and we have carefully checked our records. We can confirm that no order has been placed with us under this name, nor do we have any matching customer details in our system.
As we’re unable to identify you as a customer, this review may have been posted in error or intended for a different company.
If you believe this is a mistake, please contact us directly with your order number or relevant details so we can look into this further.
Kind regards,

Dear Michael,
You placed your order directly through our website and personally verified the part — Bomar Flagship Series Elliptical Portlights, Part No. G618-18SS — with the manufacturer prior to purchase.
Our representative also spoke with you multiple times to confirm the correct part, as this was a pre-order item, and explained the return and restocking policy. At that time, you mentioned money was not an issue as you proceed with the order.
Please note that MMarine only sells brand-new, official parts sourced directly from the manufacturer. If there are any concerns about the product’s quality, they should be directed to the manufacturer. As stated in our terms and conditions, a 25% restocking fee applies to returns.
We made every effort to assist and clarify your order, but communication from your side unfortunately ceased.
Thank you for your understanding, and please don’t hesitate to reach out if you have any further concerns or need assistance in the future.

Part machining is unfinished and I have…
Part machining is unfinished and I have to pay shipping back plus insurance that's bs.
Response from MMarine Online IncJul 15, 2025
Dear Jeremy,
Thank you for your feedback. We sincerely apologize for the machining issue with the "Mainshaft for Project 1000 Low Profile, #919." Upon learning of the defect, we immediately raised the issue with the manufacturer.
To clarify: we did provide you with a fully prepaid return shipping label via email, so your claim that we asked you to pay for shipping and insurance is not accurate. You chose to return the part, and we fully accepted this due to the defect, offering a complete refund.
We value our repeat customers and strive to handle all concerns fairly and professionally. However, we kindly ask that language used in public reviews remains respectful so that we can continue constructive conversations.
Thank you again for bringing this matter to our attention.

Unacceptable Excuses & Service
Ordered marine lights shown available. Two were backordered so they asked me for $20 more to cover 2 shipments. Paid it & waited over 2 weeks with nothing shipped. Heard a variety of excuses & finally requested a refund which was agreed to. Now the refund has been pending for 3 days & still hasn't settled to my account, which may be a bank issue. Unacceptably slow service for a parts supplier, & a waste of my time. Now having to start over 3 weeks later. Will not use again.

Dear Philip,
Thank you for sharing your feedback. We sincerely apologize for the inconvenience you experienced and appreciate the opportunity to clarify the situation.
Your review pertains to our sister company, MMRV, which operates independently with its own team and processes. However, after reviewing your case in detail with the team, we want to provide a thorough explanation of the events surrounding your order.
Your order was placed on January 19, 2025, and you were informed immediately that while two lights were in stock, the remaining two had a lead time of 4–6 weeks. At that time, we provided the option to cancel or proceed, and you chose to proceed, agreeing to the additional $20 shipping fee for split shipments (with the first shipment being free).
We also communicated that the delay was due to the manufacturer’s warehouse relocation from Maryland to Florida, which temporarily disrupted inventory access. We kept you updated throughout the process via email and telephone correspondence to ensure transparency.
Unfortunately, once the manufacturer unpacked at their new facility, they were unable to locate the two lights that were marked as in stock. On January 30th, we informed you of this update. By January 31st, you stated that, if the lights could not be found, you were willing to wait the 4–6 weeks for the shipment from Italy and have it sent to an alternative address, which we confirmed was possible.
However, on February 4th, you decided to cancel your order, stating:
"They can quit looking & issue a refund please. Things are breaking on the boat & the lights are not a priority. I'll order later in the year when Quick gets caught up."
Following your request, we immediately processed your refund. Refund details were provided as follows:
$20 refund issued on February 5, 2025 (ARN: 24011345037500062939691)
$259.44 refund issued on February 5, 2025 (ARN: 24011345037000007446829)
Refunds typically take 2–5 business days to reflect in your account, depending on your bank’s processing times.
We deeply regret the inconvenience caused by these circumstances, which were beyond our control. At no point during our communications were we made aware of an urgent deadline for the order; had we been informed, we would have gladly explored alternative solutions to better meet your needs.
We value transparency and customer satisfaction, and our team is available 24/7 via email, text, chat, and phone to assist with any concerns. We kindly ask that you reconsider your review, as we did our utmost to keep you informed and address your requests promptly.
Thank you for your understanding, and please don’t hesitate to reach out if you have any further concerns or need assistance in the future.

Shipping was terrible, and hasn't arrived yet
I selected shipping via DHL with 4 to 5 days air freight, it was sent via UPS and been 13 days to date and still hasn't arrived. Terrible service

Dear Simon,
Thank you for sharing your feedback. We value your business and would like to address your concerns in detail.
Firstly, we have been in communication from the moment your order was placed, and your shipping address in New Zealand naturally requires international processing.
Regarding the carrier, DHL’s initially displayed lead time was unfortunately inaccurate. Upon creating the shipping label, we found that UPS offered a more reliable timeframe of 3–5 business days. However, third-party carrier delays are regrettably outside of our control.
We take customer satisfaction seriously and make ourselves available 24/7 via email, text, chat, and phone to assist with any concerns. At no point during our communications did you indicate a specific deadline. Had we been aware of any urgency, we would have gladly offered guidance or alternatives before proceeding with the order.
We kindly ask you to reconsider your review, as the delays were due to factors beyond our control. We are always here to assist and ensure the best possible experience for our customers.
Thank you for understanding, and we remain available to address any further concerns you may have.

Credit cards are mandatory
Credit cards are mandatory. ACH is good but wire transfers I will never do with an online company I never heard of before.
Response from MMarine Online IncSep 20, 2023
Hello David,
Thank you for taking the time to share your experience with us. We value all feedback, and it's important to us that we address your concerns. Upon your initial phone call to us you expressed that you were not yet familiar with MMarine Online. We understand that making a purchase from a new company can raise concerns, so without hesitation we were happy to provide the assurances you needed to feel comfortable to proceed forward with your order. This included a link to our verified customer reviews page via Trustpilot in addition to our authorized dealer verification letter from Kohler to help satisfy any doubts or concerns you may have had.
Furthermore, we also provided you with several different payment options for your convenience. We understand that you initially chose to pay via ACH transfer to optimize your savings. As your order was submitted on a weekend, your order was processed on the first business day thereafter. Once receipt of payment was confirmed, your generator was scheduled to be picked up by the freight company the following business day. In the interim we received notification that a chargeback had been initiated on your end, while you have expressed your denial, it’s essential that we maintain transparency and accuracy when addressing such issues to ensure fairness and trust within our community.
After we contacted you regarding the chargeback, you then requested our wire details to complete your purchase, thereafter we didn’t receive any further correspondence from you aside from a request to cancel your order without reason.
At MMarine Online, we prioritize the trust and satisfaction of our customers. We have a proven track record of delivering quality products and exceptional service. Our team is dedicated to making every experience positive and worry-free. If you have any further questions or would like to discuss this matter in more detail, please don’t hesitate to reach out to our customer support team.

Bad Business Practice
I was sent 2 Vetus Macerator Motor that was not put together properly. I returned the 2 Motors that I paid for and received another Motor for replacement. I was told that I would receive a refund on one of the motors and did not. Now I cannot get the Salesperson to answer talk to me. Bottom line I paid for two working motors and only received one working motor. I feel that they should have refunded for the first motor.
Response from MMarine Online IncFeb 1, 2023
Hello Robert,
We take full pride in ensuring complete and total customer satisfaction and your feedback is important to us. You mentioned being sent two Macerator Motor's that were not properly put together but you failed to disclose that you returned an incomplete, used and previously installed unit. Not only is it extremely unsanitary to return a used toilet/waste product but it also demonstrates how your above review is misleading as it outlines falsified information that is not accurate.
As we at MMarine Online proudly stand behind full transparency, we've noted feedback from Vetus upon receipt of your return- "One of the unit's is missing the rubber adapter boot and hose clamp, the electrical spade connectors were clipped off and the wires bared showing signs of installation. The unit itself showed signs of being used – it was dirty, rusty, was seized, and smelled of…..USAGE. The impeller was relatively clean but the rest of the unit showed signs of contamination and smelled used – boat dirt and sealant on it and signs of water damage. Also did not function at all when powered up and was not in any form of original packing. Something that makes no sense…if the unit arrived as they claim broken/damaged in shipping, all packing materials should have been kept to show the damage or concealed damage, rather than coming back incomplete and used and seized in a random mystery box. Something does not add up…. From the look of it, the customer returned an old used unit that was broken, keeping a new one."
In regards to the second unit you purchased and returned, also due to being "damaged in transit" We've again outlined the details received from Vetus regarding your claim and return- "That one came back new and in the factory box and claimed to be broken, but it only had an impeller that was not fully tightened. The macerator motor showed zero signs of damage, this unit is new and complete and works fine – not damaged as claimed" As a result, you were informed of the outcome of the inspection performed by Vetus- The impeller was tightened to factory requirements and approved by you to be utilized as a replacement unit to satisfy your second order.
We at MMarine have gone above and beyond to accommodate and rectify what we initially believed to be an authentic issue to your order only to be swindled by a fabricated truth. Not only did we promptly remedy your initial claim of a "damaged unit in transit", we have been more than willing and available to assist you 24/7 and have continued to provide you with several options in support of your query far beyond our policy limitations. As you know based upon your 4 previous orders with MMarine, we have many sources of communication that are available and reachable 24/7 for your convenience- email, telephone, text message and chat. Needless to say there are ample methods to reach an MMarine representative at anytime!
Your refund is currently being processed, please note that the processing is also dependent upon your merchant bank. We here at MMarine will continue to honor our word despite the circumstances and experiences encountered.

Steer clear
Scam company. Ordered a trolling motor remote because they were supposedly the only ones with it in stock. They switched my receipt to show a different item (the one I was avoiding) and said it was my fault. I've ordered this part 6 times from various retailers in the past 5 years and I know the one to avoid. The one they sent doesn't even match the price on there website for the item shipped but it did match the item I wanted. They offered to take it back with a 25% re-stocking fee and would mail out a check. Wouldn't trust that in a million years from this company. They also told me it was my fault for not calling them to make sure.
Response from MMarine Online IncSep 23, 2022
Hello Justin,
We take full pride in ensuring complete and total customer satisfaction and your feedback is important to us. You mentioned the item in your order being switched upon purchase; however, as your order was self submitted, it would be impossible for us to have switched an order which you submitted. Immediately following the submission of your order, a confirmation email of the purchase was sent to you on 9/7 at 4:43pm where the details of the order including the item you purchased were outlined. If the item you ordered was incorrect this would have been the ideal opportunity to have notified us of the incorrect part. In addition, prior to an order being shipped there was yet another system generated email sent on 9/8 at 2:10pm, again the details of the part we shipped were outlined.
Needless to say, there were ample opportunities for you to have contacted us prior to receiving the incorrect part you purchased. Perhaps, this error could've been avoided had you notified us immediately after the purchase or prior to shipment that you had ordered the incorrect part.
Furthermore, according to the tracking information, you received your order on 9/12 at 2:22pm yet you didn't notify us of the incorrect part until 9/13 at 12:41pm. We would have been able to easily adjust and correct your order to suit your requirements but without being notified prior to shipment, that you ordered the incorrect part unfortunately we were unable to predict your requirements. Our policies are fair and flexible as is our level of customer service, we stand by our policies and as noted on our website any returns are subject to a 25% restocking fee.
