About Duffman Marine LLC
Duffman Marine is a mobile marine mechanic operation run by brothers Jake and Joe Duff out of Gulfport, Florida. They come to your boat — at the dock, on the lift, in the driveway, or at the ramp — with the tools and parts to handle most jobs on the first visit.
The focus is Yamaha four-stroke outboards: annual service, lower unit work, engine installations, helm and control rigging, and fuel system repair. No haul-out fees, no waiting behind a yard's full service bay. You call or text, Jake responds, and the work gets scheduled straightforwardly.
St. Petersburg, Gulfport, and South Pasadena are the home territory, with regular work extending across Pinellas County. Every job gets the same treatment — honest assessment, clear communication, and saltwater-grade attention to corrosion, anodes, and flush systems on every visit.
