Gulf Coast Power Inc has spent years earning a reputation across the Gulf Coast for honest diagnostics and dependable repairs. We're an authorized Cummins and Onan dealer, and our team includes an ASE certified diesel mechanic and Cummins certified mechanic staff who treat every engine, generator, and drivetrain with the same attention to detail.
We work on residential backup generators, commercial and industrial power systems, marine diesel engines, RV coaches, and diesel trucks.

Our mobile diesel repair vans carry the parts and tools needed for most on site diesel repair jobs, so you're not always stuck waiting for a tow or a shop appointment. When your equipment can't come to us, we come to you. We handle everything from a single generator tune-up to heavy duty diesel repair as part of that mobile service.

What a great group of people to deal with!! I had an obscure problem with my RV generator fuel pump repeatedly going out. It was under warranty but they dug into it, not only to fix the problem but to see what may be causing it to fail. It was a frustrating problem but they stuck with it, fixed it and has worked very well since.

Jim H
I was leaving on a long, multi-month trip in less than a week and my generator wouldn't start. Gulf Coast Power repaired it quickly and checked all other systems in the coach to make sure we were ready to go. I really appreciate the professional, friendly, and expert staff! I'll be a regular customer going forward!

Tom Johnson
I was very happy with the service that was done on our Tiffin Bus. The service center is wonderful, everything is done inside the new air conditioned building they just built. Definitely will be my go to service for me in the future.

Tim Mannon Sr.
I don’t remember the young lady’s name that worked on my generator but she was very efficient and explained what she was doing to troubleshoot my problem and get it repaired.
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.
What does diesel engine maintenance actually include?
A typical service includes oil and fluid service, filter replacement, and a full diesel diagnostics check on belts, hoses, and electrical connections. For customers running fleets or heavy equipment, we build out fleet diesel maintenance schedules so trucks and generators get serviced before small issues turn into major repair jobs. Regular diesel engine maintenance is almost always cheaper than an emergency breakdown.
Do you sell and install generators, or only repair them?
We do both. Our Cummins generator sales program covers residential generator service for homeowners who want reliable backup power, along with industrial generator service for businesses that can't afford downtime. Once your unit is installed, we also handle generator installation follow-up and ongoing diesel generator maintenance to keep it running.
