“These guys scheduled me quick so didn't have to wait long for my appointment. The mechanic was on-time, very helpful and knowledgeable. He fixed my issues quickly and offered to order an additional part that I needed. I highly recommend using Motorboat Mechanics for your boat repair needs. I will NOT use anyone else moving forward!“

“I had Zach service my outboard motor, and I couldn’t be happier with the experience! He changed all the fluids, filters, spark plugs, and even replaced the water pump, while also providing thorough engine diagnostics to ensure everything was running smoothly. Zach showed up right on time, was incredibly pleasant and professional, and finished the job with impressive efficiency. His attention to detail and expertise really stood out. I’d highly recommend Zach to anyone needing top-notch service.“

They are meticulous and professional in their work, ensuring everything is completed thoroughly and correctly. MDR will be the only company working on my boats from here on out. Thank you!!!!“
