Originally designed for the rigors of commercial salmon fishing in Pacific Canada, the EdgeWater 228CCD is a workhorse.  It’s also the first diesel powerboat model for EdgeWater, using a fuel-efficient Yanmar 4BY2 180 hp engine from Mastry Engine Center.

“While we’ve traditionally featured outboard power, the 228CCD evolved from a custom gas sterndrive project for a British Columbia fishing lodge,” said Peter Truslow, EdgeWater Power Boats president.  “It made us think about alternative power choices, and opportunities for superior fuel efficiency.”

Having worked with Mastry Engine Center on other custom projects, Truslow again turned to Mastry and Yanmar for the 228CCD.  “We trust Mastry and have a great comfort level with them,” he said.  “Many of our dealers worldwide say Yanmar is the preferred diesel engine.”

The Edgewater 228CCD features a rugged profile powered by a Yanmar 4BY2 180-hp diesel engine from Mastry Engine Center

The end result is a surprisingly balanced 22′ center console jackshaft setup with ample cockpit and transom space.  With the console slightly farther forward, the 180 hp Yanmar is centered and low, behind a 75-gallon fuel tank.  The Yanmar 4BY2 is a 4-cylinder, direct injection, turbocharged, common rail diesel.  Performance on the EdgeWater 228CCD is a respectable 3.96 mpg at 35.6 mph @4,150 rpm, averaging 4.49 mpg in the 22-35 mph range.

The 180-hp Yamaha 4BY2 is an efficient yet powerful engine for the Edgewater 228CCD.

“Yanmar’s diesel engine is really smooth and very quiet, with amazing range,” said Truslow.  “What shocked people is the boat’s fantastic balance.  It floats just right, with the center of gravity lower and farther forward.”

The 228CCD uses EdgeWater’s Single Piece Infusion (SPI) manufacturing process.  Vinylester resin is vacuum-infused into both the grid structures and deep-V hull laminate in one step, making the entire hull bond as one.  SPI makes EdgeWater boats stronger and lighter.  “This complements the dynamics of a modern diesel engine,” said Truslow.  “The Yanmar works really well with SPI─they’re a perfect fit.”

Exposure at EdgeWater’s recent dealer meeting and the formal product launch at the 2012 Miami Boat Show validated the diesel concept.  “The 228CCD is about simplicity and fuel efficiency,” said Truslow.

“There is a niche of people who want EdgeWater styling, and are already fans of the dependability, durability and fuel efficiency of diesels.  But we’ve also found a new market of larger boat owners who, due to gas prices, want something simpler to run around in.  We’ve built many custom boats, and the 228CCD is an entryway to explore concepts for other fuel-efficient models.”

The EdgeWater 228CCD combines a spacious, fishing-friendly layout with superior rough water handling.  Seating includes a comfortable leaning post with storage below and aft-facing seat above the engine.  An unobstructed transom and full-width swim platform appeal to fishermen and SCUBA divers.

Customers can opt for a full bench seat across the transom, a T-top with rod holders and other accessories.  Information about the 228CCD and EdgeWater’s quality line of powerboats is available at

Engines and Power


The latest 42′ models from performance builder Nor-Tech Boats serve very different types of owners.  European styling and abundant seating on the 420 MC take luxury tenders to a new level.  Nor-Tech’s fishing enthusiast customers likewise won’t be disappointed in the roomy and sporty new 420 Center Console.  But both crowds reap the benefit of outstanding performance and superior fuel efficiency from the boats’ twin Yanmar 8LV 370 hp engines supplied by Mastry Engine Center.

Both models are born from a new hand-laid fiberglass and Kevlar hull design that’s fast and fuel efficient, and provides a great ride.  “A fast hull wasn’t the top goal originally, but we ended up with one of the fastest on the market today for its size.  It’s dry and stable, running circles around many other boats,” said Terry Sobo, Nor-Tech’s director of sales and marketing.

“Yanmar’s 8LV diesel is complementary to this new hull.  It’s lightweight and cranks right up like a gas engine.  It’s extremely quiet yet creates a lot of torque,” he said.  “And the fuel consumption is amazing.”

In recent tests the 420 MC topped out at 63 mph and the 420 CC at 59 mph.  At 44 mph, both boats averaged better than 2 mpg.  The 420 MC consumed 29 gph at 52 mph, while the 420 CC burned 27 gph at 50 mph – half the fuel consumption of the typical triple 300 hp outboard setup.

“The ability to maintain the same cruise speed as the outboard package, yet cut the fuel cost in half is tremendous,” said Sobo.  “With the competitive price of the Yanmar 8LV, you’ll quickly see the fuel savings add up.”  Twin 315 hp Yanmar 6LPs are also an option on the 42′ models.

A Yanmar OEM for nearly 20 years, Nor-Tech enjoys a tight relationship with distributor Mastry Engine Center.  “We’re almost like brothers.  They work closely with us to make the best packages for our customers, they’re always right there with support and service,” said Sobo.

Sobo describes the 420 MC as a luxury cruiser with European styling.  Its 10′ beam and abundant seating accommodates 10-12 guests.  Forward of the helm are twin aft-facing lounge areas protected by a wrap-around windshield.  Farther aft are twin sunlounges and a large swim platform.

With a 30″ draft and 10′ beam, the Nor-Tech 420 CC offers a flexible floor plan.  The forward sunlounge with berth below and wrap-around forward seating is a great cruising combination.  A fishing layout with or without forward seating adds fish boxes and a bait prep/tackle station.

The EPA Tier 3-compliant Yanmar 8LV weighs about 200 lbs. lighter than a big block gas engine.  Smooth, powerful acceleration is achieved by Yanmar’s twin turbochargers and a hydraulic clutch.  The engine idles at 550 rpm and tops out at 3,800 rpm.

The 8LV is the first to use Yanmar’s proprietary CAN-bus vessel control system (VCS).  Operation is simplified with integrated full-color digital displays with NMEA2000 or J1939 gauge output, cabling and wiring.

Engines and Power


Chase 38 t-top

Novurania’s luxurious Chase 38 yacht tender and sport boat is in a class of its own.  Its generous, sophisticated amenities are fitted precisely into a sleek, deep V hull design with a high freeboard for a smooth, dry ride.  That’s fortunate because the new Yanmar 8LV-370 from Mastry Engine Center pushes this distinctive boat to previously unattained speeds.

Yanmar 8LV

“The new Yanmar 8LV is intriguing,” said Robert Collada, president of Novurania of America.  “We were never able to get the Chase 38 above 50 mph.  But with twin 370 hp Yanmar 8LV diesels, it tops out at 56 mph.  This is the fastest it’s ever gone, we’re very excited about the performance.

 “We now have greater weight capacity due to the lighter Yanmar engines, which also deliver more horsepower for their weight.  And they’re the quietest engines we’ve ever run,” he said.  Both the Yanmar 8LV 370 and 320 hp models are new options on the Novurania Chase 38, with twin Yanmar 260 hp diesels now listed as standard power.

Collada has equally positive comments on Novurania’s relationship with Mastry Engine Center, the local Yanmar distributor.  “Their team is professional and very responsive to our needs.  They assist with sea trials and are always right there to answer questions,” he said.

Novurania is so sold on Yanmar, and the support it receives from Mastry, that powerful and lightweight 260 hp diesels are also used on the Chase 31 and throughout the company’s offerings.  This includes the four-model Launch series, paired to Hamilton jet drives, and the four Custom line models, which are IO packages.  And brand new from Novurania is the Chapman series, three models with a unique opening bow for easy entry, sporting Yanmar 260 hp diesel engines with Hamilton jet drives.

The Chase 38 features a low-profile console which allows a snug fit into most yacht tender bays.  All electronics are flush mounted and incorporated into a unique fold-down POD system.  Console space is freed up for entertainment and communication equipment thanks to NMEA interfaces for gauge data through the GPS unit.  A stereo system with an iPod docking station is standard.

Elegant touches such as a side entry door, recessed swimming ladder, plush helm seats, full teak package and custom hull colors add style to the Novurania Chase 38.  Enhanced comfort for those aboard comes from leather-feel seating on the full sunpad and lounge area, a freshwater system with shower and drawer-style refrigeration unit.

Yanmar’s 8LV combines diesel’s long life with impressive performance comparable to a big block V-8 gas engine, while consuming up to 40% less fuel.  At a dry weight of 992 lbs., it’s also about 200 lbs. lighter than similar gas engines.  EPA Tier 3-compliant, the common rail fuel injected, twin turbocharged Yanmar 8LV idles at 550 rpm and tops out at 3,800 rpm.  It offers exceptionally smooth, quiet and powerful acceleration with impressive torque through a wide rpm range.

Based in Vero Beach, Florida, Novurania has been a leading design innovator for more than 40 years.  More information on the company’s sleek, powerful and distinctive models is available at
