Common questions
Answers before you call
The questions we are asked most, answered by the team that does the work.
Read all our FAQsWhat 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.
Can 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.
