The most common issue is customers ordering by horsepower alone — fitment requires matching the specific gearcase assembly and serial number to the correct diagram. The required shim thickness must be measured during assembly, not copied from the old shim stack. If you’re rebuilding a lower unit and aren’t sure which shims apply, reference your Mercury service manual or contact us with your serial number before ordering.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324693676068,"sku":"8M0063267","price":40.89,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/551cde39-956b-4e65-ab18-24264c6392ad.png?v=1788242163","url":"https:\/\/marisolmarine.com\/products\/merc-787","provider":"Marisol Marine Company","version":"1.0","type":"link"}
