Engine Reliability Offers A Kind of Magic

Abracadabra Dive Boat Powered by John Deere Marine Engine Docked in Tuscany Archipelago Harbor

Historic cities, breathtaking art, delicious local dishes and wines — Tuscany has it all! But what the tourists may not know is that, below sea level, the Tuscany Archipelago harbors some stunning beauties, from amazing corals to Roman shipwrecks. The Porto Ercole diving center, Argentario Divers, reveals these underwater secrets, which new and experienced divers reach aboard their customized, John Deere–powered dive boat Abracadabra.

Preserve, protect, and enjoy

Argentario Divers is determined to preserve this beautiful environment. "We don't use plastic in our center, we remove old fishnets we find in the sea, and we organize open cleanup days in our area," says Simone Nicolini, company owner. In 2018, they refitted the Abracadabra dive boat with new engines — twin 373-kW (500-hp) John Deere PowerTech™ 6090SFM85 engines.

"In high season, we take Abracadabra out on two- to four-hour trips covering 40 to 64 kilometers (25 to 40 miles), sometimes several times a day," Nicolini says. Therefore, engine reliability is key. "The new John Deere marine engines have improved the reliability of our excursions."

Abracadabra was designed and built specifically for diving excursions. The 17-meter-long (56-foot-long), 4.70-meter-wide (15.5-foot-wide) fiberglass diving boat caters to 20 people and their diving equipment — masks, wetsuits, fins, and diving cylinders. It provides a spacious deck for sunbathing, a large jumping platform, a well-stocked kitchen, and a hot shower for divers resurfacing from water that can drop to minus 35 degrees Celsius (minus 31 degrees Fahrenheit).

A local touch with distributor support

When repowering, owners often look for things like low vibration and engine noise as well as improved fuel efficiency over previous engines. According to Nicolini, "The main factor in our buying decision was local support. Our management suggested we switch to John Deere marine engines, based on their experiences with Rama Motori S. P.A. (a John Deere distributor in Italy)."

The engineers from Rama and their local dealer Marco Ambrogetti lived up to those expectations. "They are friendly yet professional and take the time to think about the best choices for our requirements. After studying the engine room, they suggested the twin 9.0L engines, set up the gearbox, installed the engines, and tested them on land and in the water. A year later, they are just as responsive and committed to our needs as they were then."

Greater agility with low vibration

The John Deere marine engines each drive a 4-blade propeller through a 1:2 gearbox ratio. Apart from main propulsion, they also power a water heater system. While their capacity is comparable to the original engines, the John Deere marine engines have improved the vessel's maneuverability and agility, while reducing vibration, noise, and fuel consumption.

"We've been running them for just over a year," says Nicolini. "I like how they perform when entering and leaving the dock — and in open sea. At top speed, Abracadabra reaches 18 knots, which gets us to the best diving spots in less than 1.5 hours."

A touch of Tuscany, a dash of Italian hospitality, and a pinch of magic: the perfect recipe for a diving adventure!

A year later, they are just as responsive and committed to our needs as they were then.
