Mark Milbourne, owner of Milbourne Machine in Crisfield, Maryland, is a John Deere marine dealer on the Chesapeake Bay — he holds claim as the first dealer to put a John Deere marine engine into service. That engine was a John Deere 6076AFM, which after two decades still powers a crab fishing vessel.
Milbourne likes to be among the first, especially when it comes to powering his 10-meter (32-foot) Carmen, Deere Lady, which he uses for recreation on the Chesapeake Bay. In 2001, he was among the first to install the PowerTech 6068SFM. Then, after 17 years of solid performance with that engine, he was the first to power the Deere Lady with a new 4045SFM85 engine.
Using the same Twin Disc transmission and prop, Milbourne was able to compare the performance of the two John Deere engines. Overall, the repower increased the speed and reduced fuel consumption. "Cruising 22 knots the 4045S consumes 10 gallons (37.9 liters) per hour. That's a gallon (3.79 liters) per hour better than the previous engine —a 10 percent improvement,” says Milbourne. "That's pretty impressive."
According to Milbourne, the engine's fuel delivery system, quiet noise levels, and smooth-running performance add to the engine package. "The new technologies bring a lot to the table," says Milbourne. "I can't say it loud enough: I think it's going to be a really good product for both commercial and recreational boat owners wanting good fuel economy at higher speeds. I'm certainly impressed with my own results."
