Gulf Coast Power Inc installed the Cummins Onan Generator for our home. They did an excellent job installing from the ground up (putting down the slab, to making sure the generator had all the connections necessary to make it - electrical, plumbing, permits). They did the startup demonstration, making sure we were comfortable on how the generator works. Thank you for your continued support and availability for future help or questions.

Gulf Coast Power is AWESOME!!! I bought 6 generators from Gene and he gave me the best prices by far than I could find any where in the state of Florida. He took great care and pride in helping me out when I needed these generators. 1-40K 3- 30K & 2- 20K Cummins. I would NEVER go anywhere else to buy my generators!! They are AMAZING!!! Thank you Gene for always be there for me! Brad

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.

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!

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.

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.
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.
