Volvo Penta’s Commitment

Repowered with a Volvo Penta D16 MH 750-horsepower engine last summer, the Tilly Mac, a commercial lobster boat owned by Jerome Young, has performed as promised during its first few months at sea.

Volvo Penta’s D16 engine had a lot of low-end torque that we needed to swing a big wheel – a 36-by-36 4-blade nibral. We didn’t want to have to overcome a lack of torque with a different ratio gear or with big horsepower,” says Young. “We haul more than 20,000 pounds of gear at any one time and we need to be able to push our boats to plane at this weight. The D16 had the torque and horsepower that perfectly and efficiently fit our needs.”

Following the recommended maintenance plan, Young is seeing a reduction in costs through fewer oil changes, going from once a month to every three months, and increased time between regular maintenance. “The savings from the reduced schedule adds up. Between oil, fuel, and maintenance savings, the engine will pay for itself over time,” says Young. Young will put about 200 hours a month on the engine during the nine-month season. The Tilly Mac currently has 300 hours.

He adds that his engine is burning cleaner than the previous engine. With the old motor under a heavy load, the engine was inefficient and produced excessive smoke. With the Volvo Penta engine, he’s had no smoke and a clean stern. 

“Everything that Volvo Penta promised has come true,” says Young. “I was concerned that being down in the Florida Keys I’d have trouble getting service and parts. So far, they’ve lived up to their commitment. Florida Detroit Diesel Allison has provided service within 24 hours.” 

Young has two additional boats running on Volvo Penta engines, a 43-foot commercial lobster boat in its second season with a D12 550-horsepower engine, and a 40-foot commercial fishing boat with twin D6 330-horsepower engines that is currently in sea trials.
