What Our Customers Say
Mark Cox
"I can't say enough good things about dealing with Twin Screws Marine. I first met Christina and Jimmy 4 years ago when I purchased my Grady White from them. Up front, knowledgable, honest, prompt, and accomodating all describe my experience with Twin Screws. I was so impressed with them that I came back this year to have my fishing boat repowered by them. Competitive pricing and qualtity workmanship sum up the best reasons for using Twin Screws Marine. They made smart recommendations on my project, didn't try to upcharge me for things I didn't need, and delivered my boat on time. I highly recommend calling Christina for any marine issues or projects you are contemplating. Quality people make for a great experience!"
Chip Spillane
"I can’t say enough about this operation! I spoke with Christina and Bill on the phone and they were so helpful and accommodating even though they had full load of work they recognized the jam we were in with a bad impeller. We brought the boat over on a trailer and Mike Barry and Joe all delayed their lunch so they could get the impeller in and we could get on our way. These guys really went above and beyond for us and I would highly recommend their service to anyone! They also have a very knowledgeable mechanic named Jimmy, whom they call the bearded wonder and he gave us a wealth of information that we can use in the future. Thank you again to all of you for saving our vacation. We will keep in touch! Chip"
