From powerful tugboats and elegant dinner‑cruise vessels to busy passenger ferries and private pleasure craft, KNW Diesel brings expert marine engine support directly to your dock or alongside your vessel anywhere in British Columbia. Our veteran technicians handle everything from routine day‑to‑day maintenance and emergency repairs to major onboard overhauls, when conditions allow, using full diagnostic gear and genuine components to get you back on the water fast.

When your marine engine reaches the end of its service life or needs a complete refresh, KNW Diesel’s full engine overhaul restores peak performance and extends operational life. We begin with a complete teardown and inspection of every component—blocks, heads, crankshafts, rods and ancillaries—using precision measurement tools to identify wear or distortion. Components are reconditioned or replaced with genuine OEM parts, then machined, balanced and reassembled to factory specifications. Our dyno‑tested overhauls include updated gaskets, seals, bearings and injectors, plus any necessary upgrades for enhanced reliability. Finished units leave our shop ready for on‑water commissioning, delivering like‑new efficiency and uptime.

Avoid costly downtime with a comprehensive marine survey or pre‑season engine inspection. Our certified surveyors evaluate every critical system—fuel, cooling, exhaust, controls and safety interlocks—to identify wear, corrosion or misalignment before you launch. You’ll receive a detailed report and maintenance plan to ensure peak performance all season long.

Planning a new build or replacement? KNW Diesel manages turnkey marine engine installations from hull analysis and foundation design through alignment, piping, electrical integration and commissioning. As an authorized distributor for Moteurs Baudouin, Bukh, Scania, FPT and ZF, we’ll match your vessel to the perfect power package and oversee every detail for a seamless fit.

Considering a repower? Our repower inspection service combines performance data logging, fuel‑consumption analysis and structural assessment to confirm your tug, workboat or yacht is ready for an upgrade. We’ll help you select the optimal engine model, prepare your systems for retrofit, and develop a project plan that minimizes downtime and maximizes ROI.

We can transport your engine to and from our large repair shop. There, we can diagnose, machine, and rebuild your marine engine. We believe that machinery works best with its original components, and we have specialty equipment that allows us to complete all repairs in-house.

We’ve got a lot of specialized machining tools that most shops don’t have. That’s why we’ve been known as an in-house repair shop for 3 decades. We’ve got a Rottler seat cutter, a cylinder hone, a boring bar, a Dyno, and just about everything we need to fix your marine engine.
