Marine generators run under heavy, consistent loads in hot, humid, saltwater environments. They power your air conditioning, refrigeration, battery chargers, and all onboard electronics when shore power isn't available. A failed generator doesn't just mean inconvenience — in Florida's heat, it can mean a sweltering cabin, spoiled food, and dead batteries. Regular generator maintenance is essential for reliability. Our technicians service all major marine generator brands and follow manufacturer-recommended service schedules to keep your generator running at peak performance.
Generator service goes beyond simple oil changes. We perform comprehensive inspections covering the fuel system, cooling system, exhaust system, electrical output, and mechanical components. Load testing verifies your generator produces stable, clean power at rated capacity. Exhaust system inspection catches dangerous leaks before carbon monoxide becomes a risk. Raw water cooling system service prevents the overheating that is the number one generator killer in saltwater environments.
Common signs your generator needs attention include difficulty starting, surging or unstable power output, excessive exhaust smoke, unusual noises, and overheating alarms. If your generator trips breakers, produces low voltage, or shuts down under load, these are symptoms of issues that will only get worse without diagnosis. Our technicians can diagnose the problem at your vessel and provide a clear repair plan.
For dockside diagnostic work and non-routine repairs, here's exactly how the process works — so there are no surprises from the start.
We come to your dock and diagnose the issue. There is a $175 diagnosis fee — if you approve the work, it is credited toward your final invoice. If you decide not to move forward, the visit is billed on its own and you keep the diagnosis in writing.
Based on the diagnosis, we build a written estimate and send it to you for approval through our platform. We will have a strong idea of what needs to be done — but the full picture often only becomes clear once we start taking things apart.
Once your estimate is approved and the parts arrive in-house, we schedule your job. For special-order items, we require a 50% deposit up front.
If the fix is what we anticipated, we complete the work on this visit. If we uncover something else contributing to the problem, we order the additional or replacement parts, revise the estimate, keep you updated, and schedule a second visit as quickly as possible.
When a second visit is required, we complete the service and test everything to confirm the issue is fully resolved.
When the job is done, we reconcile parts and labor to the actual amounts and send your final invoice — along with photos for your records — through our platform. Pay by ACH with no fee, or by credit card with a 3.5% processing fee.
Credited toward your invoice when you approve the work. If you pass, it is billed on its own and you keep the written diagnosis.
When a job requires special-order parts, we collect a 50% deposit up front before the work is scheduled.
Pay through our platform by ACH with no fee, or by credit card with a 3.5% processing fee. Both are always available.
