Arco 3430 Replacement Outboard Starter Motor
The Arco 3430 is a direct-fit replacement starter covering a broad range of 4-stroke outboard applications from both Yamaha and Mercury/Mariner. If your late-1990s or early-2000s 4-stroke outboard is cranking slowly or the starter has failed, the 3430 replaces the original Hitachi unit with a 13-tooth drive gear and installs without modification. It’s a reliable, purpose-built replacement for some of the most popular 4-stroke outboard engines on the water.

Parts Desk Insights
The 3430 is one of the few Arco starters that crosses between Yamaha and Mercury/Mariner — both brands used the Hitachi S114-828B in their 4-stroke outboards of this era, making this a versatile replacement. Confirm your tooth count (13-tooth) before ordering, as this is the most common fitment variable on 4-stroke outboard starters. For Mercury 4-stroke applications in the 80–115 HP range, also consider the Arco 5415, which covers a wider Mercury HP spread. For other Yamaha outboard starters, see the Arco 3426 covering Yamaha 40–50 HP 4-stroke and 115–200 HP 2-stroke applications. For other Yamaha electrical components, the Arco Heavy-Duty Tilt/Trim Motor for Yamaha Outboards is worth bookmarking for future service needs.
