Salt air, humidity, and heavy seasonal use are hard on a diesel marine engine, and a small problem left alone rarely stays small. Whether you dock at Regatta Pointe Marina in Palmetto, Twin Dolphin Marina in Bradenton, or Marina Jack in Sarasota, your engine and generator need attention from technicians who work on boats every day, not just trucks and cars. Whether you're planning a Sunday cruise on Sarasota Bay or a commercial run down the Intracoastal, your diesel engine needs to be ready.
Gulf Coast Power's marine diesel repair team combines factory training with real diesel diagnostics experience, so problems get identified correctly the first time. From a sluggish start at the dock to a generator that trips offline mid-voyage, we treat every job with the urgency a boat owner expects.
We also understand that not every repair can wait for a haul out. Our mobile marine diesel repair service brings the shop to your slip, whether you're berthed on Longboat Key, tied up in Holmes Beach, or anchored near Anna Maria Island.
Marine Diesel Repair Services
Diesel Marine Engine and Generator Repair
Boat owners across Manatee and Sarasota Counties count on Gulf Coast Power for two core areas of marine diesel work: keeping the main engine running and keeping the generator supplying power when you need it. Both services are backed by ASE certified diesel mechanics and Cummins certified technicians who understand marine systems inside and out.

Common questions
Answers before you call
The questions we are asked most, answered by the team that does the work.
Read all our FAQsCan you work on my boat's engine and generator, or just one or the other?
Both. We handle diesel marine engine repair and diesel boat generator repair as part of our marine diesel services, checking your engine and onboard generator together whenever possible. Many of our Longboat Key and Anna Maria customers have us check both systems during the same visit to save a second trip.
Do you offer mobile diesel repair, or do I need to bring my boat or RV to you?
We run a mobile diesel repair service across Anna Maria, Bradenton, Bradenton Beach, Holmes Beach, Longboat Key, North Port, Palmetto, Sarasota, and Venice. On site diesel repair means we come to your marina slip, driveway, or job site with the tools and parts to handle most diesel engine repair and diesel generator service calls without you needing to haul anything.
Are your technicians ASE certified diesel mechanics?
Yes. Our team includes ASE certified diesel mechanics with hands-on experience across marine engines, generators, and diesel trucks. We also carry Cummins certified mechanic credentials, so you're working with technicians trained directly by the manufacturer on diagnostics, repair procedures, and parts specifications rather than general guesswork.
Get Your Boat Back on the Water
A diesel engine that runs right gives you one less thing to think about on the water, whether you're headed out past Venice Inlet or spending the afternoon anchored off Bradenton Beach. Call Gulf Coast Power and put a marine diesel mechanic you can trust on the job.
