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
