YANMAR REPOWER SPELLS BIG FUEL SAVINGS FOR FLEET OWNER
The rising cost of diesel fuel can significantly cut into
commercial fishing profits, especially with an inefficient engine. But Mazatlan
businessman Jesus Loya realized a nearly $60,000 annual fuel savings after
repowering one of his fishing vessels with a new Yanmar diesel. His 69' Rio
Elota now stays at sea longer and benefits from fuel savings of over 15% with a
Yanmar 6AYM-WST turbo-charged direct injection engine.
With more than 23 years of industry experience, Jusajeli
Fishery owner Loya recognized that greater vessel engine efficiency could save
money and help increase profits for his company. Operating 28 boats off
Mexico's Pacific coast, as well as a large shrimp processing plant, the fishery
qualifies as one of the area's largest.
The 20-year-old Rio Elota works year round harvesting shark,
squid and shrimp. Loya replaced its 540 hp, 1,800 rpm CAT3412C engine with a
649 hp, 1,900 rpm Yanmar 6AYM-WST. This four-cycle, in-line six-cylinder diesel
uses a fully mechanical control system for easy servicing and reliable
performance. Like all Yanmar commercial engines, the 6AYM-WST is IMO Tier
II-compliant and provides both lower fuel consumption and lower NOx emissions.
On Rio Elota, it's paired to a keel cooling system and Kanzaki YXH-240L marine
gear with a 5.91 reduction ratio.
Loya and his captain and crew were impressed with the new
Yanmar diesel engine's fuel economy. Whereas previously Rio Elota required
14,265 more gallons of diesel to run for nearly 30 days, the Yanmar engine
extended her running time to more than 35 days. This permitted the crew to
harvest a commensurately greater catch, while enjoying increased efficiency and
a competitive advantage. By reducing a single trip's fuel needs by more than
$6,800, the Yanmar engine also created a dramatic decrease in Loya's total
Besides improving the vessel's trawling performance, the new
engine offers the added benefits of quiet operation, easy maintenance and
minimum downtime. Designed specifically for the demands of commercial marine
use, the Yanmar 6AYM-WST has a 500-hour service interval. Its fully mechanical
control system ensures simplicity and reliability at sea, unlike complex
electronic competitive engines. The lube oil filter is a convenient cartridge
type, for simple filter changes. Large inspection windows on the side of the
block allow a single mechanic to replace cylinder liners, pistons, connecting
rods, or bearings on-site if needed.
Rice Propulsion, appointed as a local dealer by Yanmar
distributor TESA Transporte y Equipo, played a key role in facilitating the
engine repower. This trusted fourth-generation business, located just two
blocks from Mazatlan's fishing fleet docks, stands ready to supply customers
like Loya with Yanmar service and support. Rice Propulsion also operates
extensive foundry and machining facilities, and manufactures and repairs marine
propellers and propulsion systems.
