It is machined from strong 3\/8 inch 6061-T6 alloy aluminum, not cast aluminum, giving it the strength to hold up under the high clamping loads of performance engines without deforming or cracking the way lighter cast plates can.\u003c\/p\u003e\u003cp\u003eIts main job is to spread bolt loads evenly across the transom surface. Without a washer plate, mounting bolts can concentrate pressure into small contact points and, over time, begin biting into the transom material, compressing the wood or coring underneath and loosening the mounting hardware. By sandwiching a rigid aluminum plate between the bolt heads or nuts and the transom, the CMC Bottom Transom Washer Plate keeps that load spread out, which helps protect the transom and keep the mounting hardware tight, particularly on high performance engines that put more stress on the transom during hard acceleration and trim changes.\u003c\/p\u003e\u003cp\u003eThe plate uses a 9-7\/8 inch hole center pattern. It is intended for use as the bottom-side counterpart in a transom mounting setup and installs using standard hand tools alongside the existing mounting hardware.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e T-H Marine CMC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 20032\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Jack Plate Accessories\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 3\/8 Inch 6061-T6 Alloy Aluminum (Not Cast Aluminum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Centers:\u003c\/strong\u003e 9-7\/8 Inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Position:\u003c\/strong\u003e Bottom (transom underside)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 733572020032\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal bottom-side transom washer plate sized to a 9-7\/8 inch hole center pattern; not restricted to a specific engine make or model in available records.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are listed for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the CMC Bottom Transom Washer Plate used for?\u003c\/strong\u003e It is a backing plate that sits against the underside of the transom to spread out the clamping load from outboard, jack plate, or Power-Lift mounting bolts, part number 20032 in 3\/8 inch 6061-T6 alloy aluminum.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat hole pattern does the 20032 washer plate use?\u003c\/strong\u003e The bottom transom washer plate uses a 9-7\/8 inch hole center pattern.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this washer plate cast aluminum?\u003c\/strong\u003e No, the T-H Marine CMC Bottom Transom Washer Plate is made from 3\/8 inch 6061-T6 alloy aluminum, not cast aluminum, which gives it more strength under high mounting loads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this transom washer plate weigh?\u003c\/strong\u003e The CMC Bottom Transom Washer Plate weighs 0.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy do I need a washer plate on my transom?\u003c\/strong\u003e A washer plate spreads bolt loads evenly across the transom instead of letting them concentrate at the bolt heads, which helps stop mounting bolts from biting into and compressing the transom, especially on high performance engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a difference between the top and bottom transom washer plate?\u003c\/strong\u003e Yes, the part described here (20032) is the bottom-side washer plate, installed on the underside of the transom; a separate top-side washer plate with a different hole spacing is sold as its own part for use on the opposite face of the transom.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 20032 washer plate come with mounting bolts?\u003c\/strong\u003e The listed contents are the aluminum washer plate itself; it is designed to be used with your existing transom mounting hardware rather than a separate bolt kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this washer plate work with a jack plate or Power-Lift bracket?\u003c\/strong\u003e The CMC Bottom Transom Washer Plate is designed as a load-distributing backing plate for transom-mounted hardware such as jack plates and Power-Lift brackets, based on its 9-7\/8 inch hole spacing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the CMC Bottom Transom Washer Plate suitable for high performance engines?\u003c\/strong\u003e Yes, its 3\/8 inch 6061-T6 aluminum construction is intended specifically to more evenly distribute mounting loads on high performance engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 20032 transom washer plate made of?\u003c\/strong\u003e It is made of strong 3\/8 inch 6061-T6 alloy aluminum, specifically not cast aluminum, for added durability under load.\u003c\/p\u003e","brand":"CMC Marine","offers":[{"title":"Default Title","offer_id":49027442868443,"sku":"T-H-20032","price":60.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/T-H-20023_lg__52261.1558133114.500.750.jpg?v=1785163481","url":"https:\/\/www.goodvibesmarina.com\/products\/t-h-marine-cmc-bottom-transom-washer-plate-3-8-inch-6061-t6-aluminum-9-7-8-inch-hole-centers","provider":"Good Vibes Marina","version":"1.0","type":"link"}
