On Bravo Three-style dual-prop systems, the front and rear thrust hubs are different parts — ordering the wrong one is the most common mistake. Always confirm which position needs replacement before ordering. If both are being replaced at the same time, 805100T (front) and 805101T (rear) are ordered separately. Anytime a propeller is removed for service, it’s good practice to inspect the thrust hub for wear before reinstalling.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324683845668,"sku":"805101T","price":65.29,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/a3903365-f9ab-4083-a07e-ecc1100e3867.png?v=1788215677","url":"https:\/\/marisolmarine.com\/products\/merc-77","provider":"Marisol Marine Company","version":"1.0","type":"link"}
