Canadian Shrimp Boat Hauling In Savings with YANMAR Repower

During shrimping season, it’s essential that boat operators have a vessel that is fully operational to maximize productivity and profits. When it came time to replace the engine in the R.J.H. No. 1 operating in the Gulf of St. Lawrence and Gaspé Peninsula in Quebec, mechanical simplicity and improved fuel economy along with a reputation for reliability resulted in a YANMAR 6AYM-WST repower.

Installed in 2015 by YANMAR dealer Enterprises Maritimes Bouchard, Inc. and supported by YANMAR distributor Diesel-Bec, the new 6AYM-WST engine runs at 659 mhp 1900min-1 coupled with a Twin Disc MG 518 ratio 5.92:1 marine gear. The 6AYM-WST is a 20.38 liter mechanical engine designed with an internal Exhaust Gas Recirculation (EGR) system using YANMAR’s ASSIGN method of combustion for improved fuel economy with lower emissions.

The R.J.H. No. 1 is a 64-foot steel boat with a 22 foot beam built in Quebec in 1984. The ship displaces 249,123 lb. with a 90,000 lb. payload.

Offering IMO Tier II compliance and built using a cell production system for complete engine assembly at the Tsukaguchi Plant, the 6AYM-WST along with YANMAR’s other commercial marine engines features a low, stable lubricating oil consumption (LOC); long overhaul interval and purpose-built marine design for easier routine inspection and maintenance.

After operating for almost 2,000 hours during its first full season of operation, the new YANMAR engine has already seen tremendous results. Even with an increased trawling speed, the engine’s improved fuel economy resulted in a savings of 14.96 liters of fuel per hour of operation with a total savings of more than $22,000 CAD for a payback period that will be nearly half of the original estimate.

When asked, Jeannot Joncas, one of the boat’s three owners, commented that he is happy to have chosen a YANMAR repower over rebuilding the existing engine because of its silent, reliable operation and improved fuel economy that will result in increased profits for their business.

Gulf Coast Work Boat Receives YANMAR’s New EPA Compliant Commercial Engine

More than 60 years of worldwide experience plus an engine designed specifically for the United States market has made a winning combination for YANMAR’s new EPA compliant commercial engine application. Push boat Sherry L, owned by E Squared Marine Services, LLC from Texas and repowered by Laborde Products, now operates even more quietly and with better fuel consumption thanks to its new 6AYAM-ET engines. In fact, according to data collected from the ship’s operation, the new engines consume 24 gallons of fuel per hour when operating at 510 mhp, resulting in an average savings of 1 to 1.5 gallons per hour over the engines they replaced.

With a need for 24 hours of continuous operation each day pushing inland barges from Channelview to Galveston and on intercostal waterways, the Sherry L can’t afford to take a day off. Thanks to its new 755 mhp engines equipped with SmartAssist, it won’t have to. YANMAR’s unique SmartAssist technology allows the engines to be monitored remotely to ensure ideal operating conditions. And, when it’s time for maintenance, the system will send out a reminder, so that maintenance can be completed on the boat’s schedule to make sure it stays in operation the maximum amount of time possible.

The 61’ Sherry L is a twin screw steel Push Boat of 152 DWT built by A&B Industries of Morgan City. The installation of the 6AYAM-ET engines was an easy repower with a propulsion package that kept the existing set of Twin Disc marine gears MG5170DC ratio 5.03, as well as existing shafts and propellers. The monitoring system consists of a conventional harness with instrument panel, and an optional M200C system that converts conventional engine data into CAN bus protocol. The engines installed work with a dual circuit (HT-LT) cooling water system, and are equipped with factory installed air starters.

Tommy Echols, co-owner of E Squared, commented, “These engines perform better than expected, while also offering quieter operation than the engines they replaced and over any other engine I have ever installed in a tug. The fuel consumption is also exceeding expectations especially for the engine’s horsepower range.”

The 6AYAM-ET is YANMAR’s newest EPA regulated commercially rated engine. With an operating performance of 755 mhp at 1,900 rpm and 20.38 liters of displacement, this 6 in-line cylinder mechanical engine is expected to be a workhorse on the United States waterways for years to come. Key features of this engine include a 500-hour service interval, torque characteristics for stable cruising, purpose built marine design including mechanically controlled injection pumps and conventional injectors designed for easy inspection and an internal exhaust gas recirculation system that doesn’t require any external control devices.

E Squared, a company offering all types of marine transportation in the Gulf Coast, chose Laborde Products, YANMAR’s local distributor, and this particular YANMAR engine not only because it met the stringent EPA Tier III requirements and fit their size and horsepower requirements, but also due to previous good experience working with Laborde.

When asked if he would recommend these new engines to others, Echols replied, “Definitely; when these engines are available for mass distribution, I will highly recommend them to any company that needs the power these engines produce. They are a great addition to the commercial diesel market since there is no other manufacturer that has this 750-800 mhp rating.”

Fuel Savings and Increased Speed Give New Life to Galapagos Charter Boat

Charter tours have always been a popular way to travel to see some amazing places; however, the tour experience can be jeopardized if the ship’s engines underperform or fail. For one Galapagos Islands charter company, replacing its older diesel engines with a pair of YANMAR 6HA2M-WHT engines has made all the difference in its ship’s reliability and performance.

Eden Land & Sea Cruise has been operating a custom-built, 80-foot long charter vessel, Eden, since 1996. Offering eight ocean view cabins for a total of 16 passengers per voyage, the ship makes four to eight day cruises and charters around the Galapagos Islands.

Installed in 2014 by YANMAR distributor Motores del Pacifico based out of Guayaquil, Ecuador and Naval Engineer Johnny Domínguez with Tecnavin S.A., the new 6HA2M-WHT engines offer 278 mhp 1880min-1 each with a total propulsion package including two steel-made gear case YX-120 ratio 2:57:1 marine gears. The 6HA2M-WHT is a simple, but high-performance engine built with quality components developed from YANMAR’s vast experience with marine engines. The 13.14 liter 6HA2 series engines from YANMAR also come in 350 and 405 mhp offerings both in 1950min-1.

In the Galapagos, where the local population is surrounded by two protected areas, the National Park and Marine Reserve, re-power projects must comply with IMO Tier II environmental regulations. Thanks to a center-mounted fuel injection pump and mechanical governor system, the engine offers improved combustion performance and increased ease of serviceability while meeting emissions requirements.

In addition to being IMO Tier II certified, all of YANMAR’s commercial marine engines are also fully mechanical with long overhaul intervals thanks to tufftride treatment cylinder liners, nitride stainless steel rings and precise clearance between the pistons and liners. These long-stroke engines also feature a purpose-built marine design, optimized flywheel weight, water-cooled exhaust manifold and special treatment injection nozzles.

As with all YANMAR commercial marine diesels, these engines are manufactured at the Tsukaguchi Plant in Japan using a cell production system that allows for the complete engine assembly to be done by one person to ensure maximum quality, efficiency and durability.

Speaking as to why he choose YANMAR and the 6HA2 series of engines, Juan Carlos Andrade, owner of the Eden, said, “I already had knowledge of YANMAR engines from previous work experiences, and I’ve always wanted to re-power with YANMAR engines…These engines are tough with excellent performance, no noise and a good propulsion system.”

At over 1,600 hours on both engines, the performance from the engines has been remarkable with a 20 percent reduction in fuel consumption, reduced engine vibration levels and increased boat speed. “I have also experienced a great difference in spare parts and maintenance savings,” shared Andrade.

Leading Cartagena Pilot Company Chooses YANMAR Commercial Marine Engines Again

When purchasing a marine engine, every customer looks for a variety of factors, including the brand’s reputation, service network and of course, their specific engine offerings. In the case of Tecnimar S.A.S., all of these aspects played a positive role in their selection of YANMAR 6HYM-WET engines for not only one application, but now, also for a second.

Tecnimar, a maritime company established in 1973, provides pilot and other related services to assist vessels in arrival, mooring, unmooring and departure to and from major Colombian ports in Cartagena, Coveñas and Tumaco.

In 2013, Tecnimar installed its first set of 650 mhp 6HYM engines in its new pilot/crew boat MALMO. The propulsion package included marine gears ZF325-1 ratio 1.05 and Hamilton WaterJets. Exceptionally designed by Boska Marine and built by Lobell’s Custom Boats in Louisiana, MALMO transports pilots, agency personnel and authorities on a daily basis without missing a day of work due to the engines since it started operation in July 2013. Today, the company is in the process of building a second pilot/crew boat, VIKINGA, featuring these same YANMAR engines.

The 13.7-liter 6HY engine series from YANMAR offers engines in a variety of horsepower ratings, including 500 mhp at 1,950 rpm, 600 mhp at 2,100 rpm, 650 mhp at 2,150 rpm and 700 mhp at 2,200 rpm. This series is IMO Tier II compliant for use in non-EPA regulated areas, and offers fully mechanical control along with a purpose built marine design, including a long service interval and minimum special tools needed. As with all YANMAR commercial marine diesels, these engines are manufactured in Japan at the Tsukaguchi Plant using a cell production system that allows for the complete engine assembly to be done by one person to ensure maximum quality, efficiency and durability.

When asked why the company chose YANMAR, Roberto Cavelier, general manager for Tecnimar, said, “YANMAR has a very good global reputation for reliability, so it made sense to install the 6HYM engines when we found out that their compact design fit perfectly in our boats for what we need.”

Cavelier continued on to say that the company has had a great experience so far with the engines that are installed in MALMO. For him, another important aspect when choosing an engine company is the level of service. “Whenever we have needed help with preventative or corrective maintenance, TODOMAR has been a local and reliable support for us. We have also received excellent service from our local YANMAR representative.”

Todomar C.H.L. Marine H.S.H., the YANMAR dealer in Cartagena, is a manufacturer of commercial and sport boats and launches. They provide solutions and supplies for all kinds of marine products to service marinas and shipyards and ship owners.

As if the repeat order of YANMAR commercial engines wasn’t testament enough, Cavelier concluded, “We are very happy with the performance of these engines, and I am very excited to install the second pair in our new boat. I definitely recommend YANMAR commercial engines to others due to their reliability and because of the company’s dedication to local service. We plan to do business with YANMAR and TODOMAR for many years to come.”
