Quick answer: Scarano Marine provides mobile marine diesel engine service throughout the Florida Keys — the full chain from Key Largo to Key West. We’re an authorized MAN and John Deere Marine dealer, also certified on MTU engines, dispatching from Miami with same-day response as far south as Marathon and overnight trips beyond. Our 24/7 emergency line covers the Keys, weekends included.
Full-Chain Coverage, Key Largo to Key West
The Keys are part of our regular service territory, not an occasional exception. Our technicians work at marinas and private docks down the entire chain, including:
- Key Largo: Ocean Reef Club
- Islamorada: Safe Harbor Islamorada
- Duck Key: Hawks Cay Marina
- Marathon: Safe Harbor Marathon Marina, Marathon Boat Yard, Bonefish Marina
- Key West: Galleon Marina, Conch Harbor Marina, Oceanside Marina
Response logistics, stated plainly: we run same-day service calls as far south as Marathon. Anything further down the chain — including Key West — typically requires an overnight trip, which we plan with you so the vessel’s schedule drives the visit, not ours.
An Authorized Dealer That Comes Down the Chain
For engines under factory or extended warranty, who performs the service matters: authorized dealer work is factory-documented and warranty-compliant. Scarano Marine brings full MAN and John Deere Marine dealer authorization down the chain — genuine OEM parts, official factory diagnostic systems, and technicians who spend roughly 90% of their hours on MAN engines specifically. That concentration means the technician stepping aboard in Marathon has almost certainly seen your exact engine, and likely your exact problem, before. We’re also certified on MTU engines and actively service MTU installations throughout the Keys.
Real Work in the Keys
One of our long-standing customers bought his 44′ Cabo with a MAN R6-800 in Miami and took it home to Marathon. He kept calling us. We’ve been going to that boat ever since — the full 1,000-hour service, repairs, the routine work in between — because he’d rather wait for the technicians who know his engine than hand it to whoever’s closest. That’s most of our Keys business in one sentence: owners who established trust in Miami or Fort Lauderdale and take it with them down the chain.
The emergency side works too. On a Saturday, we took a call from a 110′ Riva Dolcevita with MTU 16V2000 M96L engines in Marathon, headed further south, with a raw water leak on a heat exchanger. Our team responded, and the vessel kept its schedule. A weekend emergency on a superyacht in transit is exactly the situation the 24/7 line exists for — and exactly where a shop’s real capability shows.
In April 2026, Princess Yachts America hosted its annual Princess Spring Owners Holiday at Ocean Reef Club in Key Largo — and Scarano Marine was invited as a vendor representing MAN service. When a builder brings its owners together and wants MAN expertise in the room, that’s the level of service relationship we maintain in the Keys.
Parts, Delivered Down the Chain
Genuine MAN and John Deere Marine parts ship to the Keys from our Miami parts operation and online store, and our technicians bring required parts down on service calls — so a vessel in Islamorada isn’t waiting on a part that has to find its own way down US-1.
