Cast in high-strength aluminum, it evenly distributes the repeated shock and flex loads that a transom absorbs during fast starts, high-speed running, and sharp turns, helping prevent the cracking and fatigue that develop around outboard or sterndrive mounting points over time. This is the 4 inch by 17 inch heavy-duty size, sold as a single retail unit, and finished in gray powder coat for corrosion resistance in a marine environment.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward: the plate mounts using two bolts (not included) on a 12-15\/16 inch bolt pattern, allowing it to be added to an existing transom without extensive modification. Because it reinforces from the exterior surface of the transom, it is a practical upgrade for boat owners looking to add strength and extend the service life of the transom without pulling the outboard or replacing the transom core. At 3 pounds, it adds meaningful reinforcement without adding significant weight to the stern.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Springfield Marine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 1780203\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e Tuff'Ner Heavy-Duty Transom Support Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 4 inches x 17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Pattern:\u003c\/strong\u003e 12-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware:\u003c\/strong\u003e Two bolts, not included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cast aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Gray powder coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 (retail)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 038132512030\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThe Tuff'Ner 1780203 is a universal-fit transom support plate intended for surface mounting to a boat transom using its 12-15\/16 inch two-bolt pattern; it is not restricted to a specific boat make, model, or engine.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Springfield Tuff'Ner 1780203?\u003c\/strong\u003e The Springfield Marine Transom Tuff'Ner 1780203 measures 4 inches by 17 inches, making it the heavy-duty size in the Tuff'Ner support plate line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat bolt pattern does this transom support plate use?\u003c\/strong\u003e It mounts on a 12-15\/16 inch bolt pattern using two bolts, which are not included with part 1780203.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Transom Tuff'Ner made of?\u003c\/strong\u003e It is cast in high-strength aluminum and finished in gray powder coat for corrosion resistance in marine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 1780203 Tuff'Ner include mounting bolts?\u003c\/strong\u003e No, the two bolts needed to mount the Tuff'Ner 1780203 to the transom are not included and must be sourced separately to match the 12-15\/16 inch bolt pattern.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Springfield Tuff'Ner 1780203 weigh?\u003c\/strong\u003e This transom support plate weighs 3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Transom Tuff'Ner actually do?\u003c\/strong\u003e The Tuff'Ner adds strength to a boat's transom by evenly distributing the forces generated during fast starts, high-speed runs, and sharp turns, helping reduce transom fatigue over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Springfield 1780203 the heavy-duty or economy version?\u003c\/strong\u003e Part number 1780203 is the heavy-duty Tuff'Ner, sized 4 inches by 17 inches; Springfield also offers a smaller economy version in a different size under a different part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the Tuff'Ner 1780203 fit my boat?\u003c\/strong\u003e The Tuff'Ner 1780203 is a universal surface-mount transom support plate that installs with a 12-15\/16 inch two-bolt pattern, so it is not limited to a specific boat make or model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many Tuff'Ner plates come in one package?\u003c\/strong\u003e Springfield part 1780203 is sold as a single retail unit, one plate per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Springfield Transom Tuff'Ner?\u003c\/strong\u003e The 1780203 Transom Tuff'Ner has a gray powder coat finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to remove my outboard to install the Tuff'Ner?\u003c\/strong\u003e The Tuff'Ner 1780203 mounts to the transom surface with two bolts on its 12-15\/16 inch bolt pattern, so installation does not require removing the transom core.\u003c\/p\u003e","brand":"Springfield","offers":[{"title":"Default Title","offer_id":49025166213339,"sku":"S-M-1780203","price":72.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/1780203__42132.1722513560.500.750.jpg?v=1785329206","url":"https:\/\/www.goodvibesmarina.com\/products\/springfield-marine-transom-tuffner-heavy-duty-support-plate-4-x-17-inch-part-1780203","provider":"Good Vibes Marina","version":"1.0","type":"link"}
