EdgeWater 228 CCD

Here’s a case where demand bred ­innovation

The Peregrine Fishing Lodge in British Columbia contacted EdgeWater Boats with a unique request. The lodge needed heavy-duty center‑consoles that could handle the rough waters of the region’s salmon fishery, but with the power plant located amidships to keep the weight forward and create more cockpit space.

EdgeWater modified its venerable 228 CC and delivered to Peregrine a boat with a gasoline inboard jack-shafted to a sterndrive. Then, EdgeWater president Peter Truslow and his crew thought, “Why not a small diesel?” The result is the new 228 CCD, a center-console that surprises with its maneuverability and efficiency.

Performance

The 228 CCD is powered by a Yanmar 4BY2-180z, which is actually a ­marinized inline-4 BMW engine. Paired with Yanmar’s ZT370 sterndrive, the little diesel makes the boat do ­interesting things. Hitting the throttles, I experienced a slight delay as the diesel “wound” up, but I felt absolutely no squat as the boat planed.

The boat holds plane at 2,500 rpm and around 15 mph, where it burns a paltry 4 gallons per hour (equal to about 3.7 mpg). Its sweet spot is around 3,500 rpm, where it hits 27.4 mph and burns 6.3 gph, which translates into roughly 4.4 mpg.

But the beauty of a diesel is you can run one just a hair off wide-open throttle for extended periods without damaging the engine; with three aboard and full fuel, we topped out at 35 mph (4,100 rpm), getting just under 4 mpg. That’s about a mile per gallon better than what the 228 CC burns at 35 mph with an F250 outboard (according to Yamaha performance bulletins).

Handling is where the 228 CCD really shined. Moving the engine amidships altered the boat’s center of gravity, but EdgeWater made no alterations to the running surface. In fact, when Marine Concepts performed hydrostatic tests, it predicted that moving the engine forward would make the boat perform better. The company was right.

The 228 has a level running attitude, and handles wakes and chop with grace. Turning the wheel hard over at 30 mph, I carved tight, arcing turns with no fear of prop blowout — a feat not possible with outboard power.
