Tailored for marine environments, these mounts excel in absorbing both forward and reverse propeller thrust while effectively isolating drivetrain vibrations from the hull. Enhanced longevity is ensured through zinc-plated and pasivated steel components, alongside a petroleum-resistant oil shield over the rubber parts. Preloaded to minimize engine movement and designed with height adjustability and slotted mounting holes, these mounts simplify the drivetrain alignment process, ensuring a secure and straightforward installation.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eCapable of handling significant propeller thrust, minimizing vibration transmission.\u003c\/li\u003e \u003cli\u003eZinc-plated and pasivated steel for superior corrosion resistance.\u003c\/li\u003e \u003cli\u003eRubber components protected from petroleum products.\u003c\/li\u003e \u003cli\u003eAdjustable height and preloaded design for optimal engine stability.\u003c\/li\u003e \u003cli\u003eSlotted mounting holes for easy and accurate drivetrain alignment.\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eSelecting the Perfect Mount for Your Marine Engine\u003c\/h4\u003e \u003cp\u003eFor a tailored fit and enhanced engine performance:\u003c\/p\u003e \u003col\u003e \u003cli\u003eDetermine the total combined weight of your engine and transmission.\u003c\/li\u003e \u003cli\u003eCalculate 60% of this weight for the rear mounts and 40% for the front mounts, then divide accordingly to find the necessary capacity for each mount.\u003c\/li\u003e \u003cli\u003eSelect the appropriate stud diameter and footprint for your setup.\u003c\/li\u003e \u003cli\u003eOpt for a mount that falls within the middle of your weight range for balanced support.\u003c\/li\u003e \u003c\/ol\u003e","brand":"R \u0026 D Marine","offers":[{"title":"Default Title","offer_id":52023464984757,"sku":"QBP640867","price":148.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1217688_qbp640867.jpg?v=1763254999","url":"https:\/\/www.qualityboatparts.com\/products\/qbp640867","provider":"Quality Boat Parts","version":"1.0","type":"link"}
