It is engineered to mesh with the pinion and reverse gears inside the lower unit to deliver efficient power transfer when the engine is shifted into forward gear. This component is commonly installed in Mercury 35, 40, 50, and 60 HP EFI four-stroke outboard engines with compatible gear housing assemblies. Designed with precision-machined teeth and durable marine-grade materials, the gear supports consistent propulsion and long-term drivetrain reliability.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong data-end=\"1102\" data-start=\"1085\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eForward Gear Assembly: Transfers rotational power to the propeller shaft when the outboard operates in forward drive.\u003c\/li\u003e\n\u003cli\u003eMercury OEM Component: Manufactured to factory specifications for proper fit and drivetrain compatibility.\u003c\/li\u003e\n\u003cli\u003e1.83:1 Gearcase Compatibility: Designed for gear housings with a 1.83:1 gear ratio.\u003c\/li\u003e\n\u003cli\u003eMulti-Engine Fitment: Compatible with Mercury 35–60 HP EFI four-stroke outboard engines.\u003c\/li\u003e\n\u003cli\u003ePrecision-Cut Gear Teeth: Ensures smooth engagement with pinion and reverse gears inside the gearcase.\u003c\/li\u003e\n\u003cli\u003eMarine-Grade Construction: Built to withstand high loads, vibration, and continuous marine operation.\u003c\/li\u003e\n\u003cli\u003eLower Unit Integration: Designed to operate within the outboard gear housing assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 859101T03 delivers the reliability and precision required for efficient power transfer within marine outboard lower unit drivetrain systems.\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":51231544246570,"sku":"859101T03","price":825.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l300_b6b85b56-b60e-4677-9f45-298f433e53ed.webp?v=1773254845","url":"https:\/\/iqelectro.com\/products\/mercury-859101t03-forward-gear-assembly-reliable-delivery","provider":"IQElectro","version":"1.0","type":"link"}
