Swap that rusty hardware for Suzuki’s Bolt, Protection (09103-06281) and lock your DF-series outboard parts down the way the factory intended. This is the short M6 fastener that secures prop-shaft anodes, intake screens, and other exposed fittings—places where ordinary steel bolts seize after a single season.

Why the genuine bolt is worth the two-minute swap

• Marine-grade stainless core resists salt spray and electrolysis far better than zinc-plated hardware.

• Integrated flange head spreads clamping load, saving soft aluminum castings from crush marks.

• Precisely rolled M6-1.0 threads mate cleanly with tapped holes in DF40-DF140 and DF150-DF300 housings—no cross-thread drama.

• Low-profile 10 mm hex clears tight recesses around anode plates so you can torque it without scraping paint.

Practical payoff? A snug fit that stays put through hole-shots, hard reverses, and long idle runs—plus the confidence of knowing your sacrificial anodes and splash-zone covers will come off cleanly next service, not with a snapped stud. Keep a pair of these bolts in your onboard toolkit; they’re small insurance for the bigger metal they protect.
