The rubber-isolated design supports the drivetrain while absorbing vibration and allowing fine engine alignment adjustments. Correct rear mount installation is essential for maintaining engine-to-transmission and propeller-shaft alignment — a deteriorated or incorrect mount can introduce vibration and accelerate drivetrain wear.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCrusader Model 270 \/ 350 CID \/ 5.7L — documented as the starboard long-shaft dual rear mount in applicable configurations\u003c\/li\u003e\n  \u003cli\u003eCrusader MP6.0L \/ 366 CID 6.0L — dual rear engine mounts (qty 2) with Hurth transmission mounting brackets\u003c\/li\u003e\n  \u003cli\u003eCrusader MP8.1L \/ 496 CID 8.1L — dual rear mount support (qty 2) in the engine\/transmission mount system\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment note — trunnion shaft diameter:\u003c\/strong\u003e The 97905 uses a \u003cstrong\u003e1-inch diameter trunnion shaft\u003c\/strong\u003e.

However, older diagrams distinguish these as different shaft lengths (97905 = 3.00 in. long-shaft, 97906 = 2.13 in. short-shaft). Confirm your bracket configuration and shaft requirements before substituting 97905 into a 97906 position on an older engine.\u003c\/dd\u003e\n\n  \u003cdt\u003eMy engine has a 7\/8-inch mount — will 97905 fit?\u003c\/dt\u003e\n  \u003cdd\u003eNot directly. The 97905 uses a 1-inch trunnion shaft.

It consolidates several older superseded part numbers under one current SKU, making it the correct choice for most rear-mount replacement jobs on these engine families. It ships as a single mount — confirm quantity needed before ordering, as twin-mount applications require two.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon customer questions:\u003c\/strong\u003e The most frequent point of confusion is trunnion shaft diameter — customers with older engines may have 7\/8-inch mounts and assume 97905 is a direct swap. It is not without bracket verification. The 97905 vs. 97906 distinction also comes up regularly: current catalogs consolidate them, but customers with older part numbers from engine diagrams should be advised to confirm shaft length and bracket compatibility before completing the order. When in doubt, ask for the engine model, year, and existing part number.\u003c\/p\u003e","brand":"FVW","offers":[{"title":"Default Title","offer_id":43563794825252,"sku":"97905","price":178.63,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/247d606e-687e-4bdd-8846-58c3d07ec71e.png?v=1788723784","url":"https:\/\/marisolmarine.com\/products\/crusader-dual-eye-rear-engine-mount-97905","provider":"Marisol Marine Company","version":"1.0","type":"link"}
