Diesel Engines

more service friendly” than electronically controlled engines, said Laborde. In fact, Mitsubishi Marine engines are the only Tier 3 mechanical diesel engines in the workboat market, according to Mitsubishi.

The Mitsubishi S12R weighs in a bit heavier than some of its competition at 11,731 lbs. for 1,100 hp. That might be a concern if the intent was to repower a high-speed or relatively high-speed workboat, but for vessels such as towboats and tugboats the engine’s weight “does not affect fuel consumption,” said Laborde. “These are displacement-hull vessels. They don’t need to go fast and that’s the right application for a Mitsubishi engine.”

Yanmar

Workboat operators with vessels based in Canada now have the option of a new Yanmar engine model with an SCR system that allows it to meet IMO Marpol Tier III emissions requirements for nitrous oxides, or NOx. It’s the 6EY17WS, an in-line six-cylinder engine based on the existing 6EY17W engine, with a horsepower range of 501 to 1,122. (If sold in the U.S. it would have to meet Tier 4 requirements, but not in Canada.) The SCR system, which is a Yanmar product designed for Yanmar engines, reduces NOx emissions by about 80% compared with IMO’s Tier I standards, said Nathan Stabler, senior marine engineer at Yanmar America. Yanmar’s new engine is available with Yanmar gearboxes with ratios from 2.5:1 to 5:1. The rst Yanmar 6EY17WS is going into a 73' crabber due to be launched next spring in New Brunswick, Canada. That’s to be followed by a second vessel in August and a third in spring 2024.
