Quick answer: Scarano Marine provides specialized sportfish MAN engine service — for Viking, Winter Custom, Riviera, and other sportfishermen — throughout South Florida and internationally. We service the full sportfish MAN range, from the V8-1200 through the V12-1550, V12-1800, V12-1900, and V12-2000 to the new V12X-2200 going into the 70 Viking. Many of our sportfish relationships span more than ten years and multiple boats, and we travel to our customers — from Viking Service Center and Rybovich to El Salvador and St. Thomas.
I’m Adolfo Scarano — marine engineer, former Merchant Navy chief engineer, and founder of Scarano Marine, an authorized MAN and John Deere Marine dealer. Sportfish boats are a world of their own, and the people who run them know the difference between a shop that services their engines and a shop that understands their boats. After more than a decade on these vessels, here’s what sets our sportfish MAN engine service apart — and what that difference actually looks like.
Sportfish Roots on the Miami River
Our connection to sportfish boats goes back further than MAN itself. Early in his career, Adolfo ran the commissioning sea trials on Bertrams coming straight out of the Bertram Yacht factory, which sat on the Miami River. The routine was simple and demanding: take a brand-new boat out of the river, run it into the ocean, and prove the engines before it went to the sales team and its owner. Those Bertrams ran Detroit Diesel Series 71 and 92 engines, and running trial after trial on hull after hull is how you learn what a sportfish boat is supposed to feel like under power — knowledge that carries directly into diagnosing a MAN today. Long before we were the MAN sportfish specialists, the founder was signing off on sportfish boats at the factory dock.
Relationships That Follow the Owner From Boat to Boat
The clearest sign you’re doing sportfish service right is that owners keep you when they upgrade. A customer in Deering Bay, Miami, bought a 48 Viking with MAN V8-1200 engines, and we ran all his services — M1, M2, M4 — until he sold it and moved up to a 55 Viking with MAN V12-1550s. We kept doing everything, the full M1/M2/M4 schedule, and when he had cracked turbocharger housings, we handled those too. Same owner, new boat, same team. That pattern repeats across our sportfish customers, and it’s the whole point: these owners don’t shop around every season, because they’ve found people who know their engines.
The El Salvador Group: Service That Travels
Some of our longest sportfish relationships aren’t in Florida at all. In El Salvador, we take care of a group of friends who all run sportfishermen — a 64 Viking with MTU 16V2000 M90, a 68 Viking with MTU 16V2000 M93, and a 48 Viking with MAN V8-1200 among them. We’ve been serving these boats for more than ten years, traveling down to keep the whole fleet running. It’s the kind of arrangement that only works when the customers trust the team completely — because when you’re that far from home, the person who shows up has to get it right the first time.
From Fort Lauderdale to St. Thomas, and Wherever the Boat Goes
A customer with a 52 Viking and MAN V12-1550 engines had us perform the 1,000-hour M4 service in Fort Lauderdale before he took delivery and ran the boat to St. Thomas. We’ve since traveled back to St. Thomas for more service and repairs whenever he needs us. On a 53 Winter Custom yacht with MAN V12-1550 power, we did the pre-purchase survey and have taken care of the boat ever since — he’s usually found at Viking Service Center or Rybovich. And on a 65 Viking running MTU 16V2000 M91s, we’ve done countless in-frame overhauls over the years. Different boats, different builders, different engines — the constant is that the owners keep calling us.
Why a Sportfish Engine Room Is Its Own Skill
Here’s something a general marine mechanic learns the hard way: a sportfish engine room is nothing like a motoryacht’s. Access is usually through a small door that doubles as a step down into the space. Headroom over the engines is tight — and that space is often exactly where the crew hangs the fishing reels. The outboard sides are packed with converters and air conditioning units. Moving through that engine room, doing real work, without breaking or knocking loose something expensive takes specific experience. Our technicians have spent years in these spaces; they know how to maneuver inside a sportfish engine room, which is not a skill you can pick up on the first job.
Sportfish MAN Engine Service: Why Hard-Run Engines Wear Differently
Sportfish boats run a demanding duty cycle. Long runs offshore at high RPM to reach the fish, heavy loads while trolling, and wide-open-throttle bursts the moment something hits the spread. That harder running accelerates wear compared with a motoryacht that idles out to a sandbar — which means staying on the MAN factory maintenance schedule matters more on a sportfish, not less. As a reference point, here’s the measured fuel consumption on a 48 Viking with MAN V8-1200 engines, per engine, across the RPM range:
Trolling / low RPM: roughly 6 gal/h per engine. Efficient cruise: mid-teens to low-20s gal/h. Fast cruise: mid-30s to low-40s gal/h. Wide open throttle: low-to-mid 60s gal/h per engine.
Numbers like these aren’t trivia — they’re how we and the owner understand how the boat is actually being used, and how hard the engines are working between services. Reading the real data, not guessing from the sound at the dock, is the foundation of doing this right.

Frequently Asked Questions
Who services MAN engines in sportfish boats in South Florida?
Scarano Marine, an authorized MAN and John Deere Marine dealer, specializes in MAN engine service for sportfish boats throughout South Florida and internationally. The team services Viking, Winter Custom, Riviera, and other sportfish yachts at Viking Service Center, Seminole Marine, Willis Custom Yachts, Rybovich, and dockside, and travels to customers as far as El Salvador and St. Thomas.
Which MAN engines are used in sportfish boats?
Common MAN engines in sportfish boats include the V8-1200 and the V12 series — V12-1550, V12-1800, V12-1900, and V12-2000 — with the new V12X-2200 now being installed in the 70 Viking. Scarano Marine services the full range.
Does hard running wear out a sportfish engine faster?
Sportfish boats run demanding duty cycles — long high-RPM runs offshore, heavy trolling loads, and wide-open-throttle bursts on a hookup — which accelerates engine wear compared with a typical motoryacht. Staying on the MAN factory maintenance schedule (M1, M2, M4) matters more, not less, on a hard-run sportfish engine.
Can Scarano Marine service my sportfish boat outside Florida?
Yes. Scarano Marine travels internationally for sportfish customers, including a long-standing group in El Salvador and vessels in St. Thomas, and ships genuine MAN parts worldwide. Many relationships span 10 or more years across multiple boats.
Why does servicing a sportfish engine room require specialized experience?
Sportfish engine rooms are tight. Access is often through a small door that doubles as a step, headroom over the engines is limited and frequently used to stow fishing reels, and outboard sides are packed with converters and air conditioning units. Working in that space without damaging anything takes specific experience that a general marine mechanic may not have.
