The Mercury Stretch-Belt Installation Tool - 91-8M0146862 turns a knuckle-busting job into a two-minute task. Designed for late-model Verado, V-6, and V-8 outboards that use single-use "stretch" alternator belts, this low-profile jig hooks over the flywheel and guides the belt onto the pulley as you bump the starter-no pry bars, no torn cords, and no risk of nicking that pricey belt.. Forged, zinc-plated steel shrugs off salt and the odd drop on the shop floor, while a molded hand pad gives you solid grip even with oily gloves. The tool's stepped throat matches Mercury's 5- and 6-rib pulleys, so alignment is perfect every time.. Why it belongs in your onboard toolkit. Model-specific fit: engineered for 175-300 hp V-6 & V-8 FourStroke and 300 hp Verado blocks.. Protects new belts: smooth radius prevents kinks or edge fray during install.. One-hand operation: lets you keep the other hand on the ignition key for precise bumping.. Built to last: corrosion-resistant finish and welded handle
