the Koehler Kraft 28 powerboat charging down the bay


Our 75 years of experience in boat building and service has enabled us to produce a power cruiser unmatched by anything that comes off a production line. No two KK28s are the same.

Volvo Penta engine example


At the heart of the KK28’s power center is its Volvo Penta D6 engine. This 6-cylinder, turbocharged diesel outputs 370hp to propel the KK28 with baffling ease, while maintaining a calm composure. This makes the boat agile and responsive, whether you’re entertaining at low speeds or pushing 33 knots in the bay.

Simrad navigation display example


Technology aboard the KK28 may appear understated, but its capabilities are not. Absent from the interior landscape are blinking lights, knobs, and a dozen panels and gages. This is because Koehler Kraft integrates all technologies into a single robust multi-function display: GPS, 4G radar, engine management and diagnostics, chart plotter, fish finder, and much more. Best of all, we’ll make sure you’re comfortable using each feature before your KK28 leaves the yard.
