Lost that rubber key boot somewhere between the dock and the driveway? Slide on Suzuki’s Cap, Key (37143-99E01) and bring back the snug, weather-tight feel your helm was born with. This genuine OEM cover slips over the metal blade of DF-series ignition keys, adding a soft, high-grip sleeve that protects both your fingers and the switch tumbler.

Why owners keep a spare in the glove box

• Molded EPDM rubber stays flexible in freezing dawn launches and steamy summer afternoons—no cracking or sticky feel.

• Micro-ribbed exterior gives wet hands (or gloves) extra traction, so starts are quick and fumble-free.

• Moisture barrier lip seals the key slot, blocking spray and salt crystals that corrode contacts.

• High-visibility black with embossed “S” logo matches the factory look on every DF40-DF300 dash panel.

Press it on in seconds and you’ll notice smoother key turns, a cleaner switch cavity, and the peace of mind that your next start will spark on the first twist. Small, simple, and 100 percent Suzuki—exactly what dependable days on the water are built on.
