They do not share this bearing — the 72C \/ 10-18 forward housing takes a different part. Pull the identification plate number before ordering, and double-check whether the unit is a 10-17 or 10-18 to avoid a costly wait for the correct bearing on an otherwise straightforward rebuild.\u003c\/p\u003e","brand":"BOR","offers":[{"title":"Default Title","offer_id":43563779948580,"sku":"B107A","price":74.82,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/d496df2d-c7c6-4392-b8de-ac93f05c8dd0.png?v=1788810342","url":"https:\/\/marisolmarine.com\/products\/velvet-drive-71c-forward-piston-housing-bearing-b107a","provider":"Marisol Marine Company","version":"1.0","type":"link"}
