Built from Marine-Grade Aluminum.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf your outboard is blowing out, struggling to get on plane, or losing efficiency at speed, the problem might be your cavitation plate — or the lack of a quality one. Our custom-fabricated aluminum cavitation plates are CNC-cut and hand-bent from 3\/16\" marine-grade aluminum, built to improve your boat's holeshot, reduce prop cavitation, and give you a more stable, efficient ride from the moment you throttle up.\u003c\/p\u003e\u003ch2\u003eChoose Your Design\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eNotched\u003c\/strong\u003e — Engineered for a faster holeshot. The notched cutout allows water to release quickly off the plate, reducing resistance as your boat climbs onto plane. Ideal for shallow-water fishing rigs, duck boats, and jon boats where getting up fast matters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFlared\u003c\/strong\u003e — Built for lift and stability at lower speeds. The flared edges redirect water flow to generate upward force under the hull, keeping your bow from porpoising and your ride smoother in choppy water.\u003c\/p\u003e\u003ch2\u003eFitment Guide\u003c\/h2\u003e\u003cp\u003eSmall — 15 to 35hp outboards\u003cbr\u003eMedium — 40 to 60hp outboards\u003cbr\u003eLarge — 60 to 90hp outboards\u003c\/p\u003e\u003ch2\u003eFinish Options\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eRaw Aluminum\u003c\/strong\u003e — Ready to paint or match your existing boat color.

We use 3\/16\" marine-grade aluminum (heavier and more rigid than the thin-gauge plates found on Amazon), and each one is CNC-cut for consistent fitment. Optional bolt holes make installation straightforward with standard hardware.\u003c\/p\u003e\u003ch2\u003eNeed Something Custom?\u003c\/h2\u003e\u003cp\u003eEvery boat is different. If your motor is outside the standard size ranges, or you need a specific notch pattern, bolt spacing, or profile, reach out before you order. We fabricate custom cavitation plates for unusual setups, high-performance rigs, and commercial applications. Contact us with your measurements and we'll build it.\u003c\/p\u003e\u003ch2\u003eSpecs at a Glance\u003c\/h2\u003e\u003cp\u003eMaterial: 3\/16\" marine-grade aluminum | Designs: Notched, Flared | Sizes: Small \/ Medium \/ Large | Finish: Raw or Black Powder Coat | Bolt Holes: Optional | Made to order in the USA\u003c\/p\u003e","brand":"FMS","offers":[{"title":"Small Flared \/ Raw Aluminum \/ Without","offer_id":45710878113981,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true},{"title":"Small Flared \/ Raw Aluminum \/ With","offer_id":45710878146749,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true},{"title":"Small Flared \/ Black Powdercoat \/ Without","offer_id":46659404431549,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true},{"title":"Small Flared \/ Black Powdercoat \/ With","offer_id":46659404464317,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true},{"title":"Small Notched \/ Raw Aluminum \/ Without","offer_id":45710878376125,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true},{"title":"Small Notched \/ Raw Aluminum \/ With","offer_id":45710878408893,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true},{"title":"Small Notched \/ Black Powdercoat \/ Without","offer_id":46659404497085,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true},{"title":"Small Notched \/ Black Powdercoat \/ With","offer_id":46659404529853,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true},{"title":"Medium Flared \/ Raw Aluminum \/ Without","offer_id":46659404562621,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true},{"title":"Medium Flared \/ Raw Aluminum \/ With","offer_id":46659404595389,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true},{"title":"Medium Flared \/ Black Powdercoat \/ Without","offer_id":46659404628157,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true},{"title":"Medium Flared \/ Black Powdercoat \/ With","offer_id":46659404660925,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true},{"title":"Medium Notched \/ Raw Aluminum \/ Without","offer_id":46659404693693,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true},{"title":"Medium Notched \/ Raw Aluminum \/ With","offer_id":46659404726461,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true},{"title":"Medium Notched \/ Black Powdercoat \/ Without","offer_id":46659404759229,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true},{"title":"Medium Notched \/ Black Powdercoat \/ With","offer_id":46659404791997,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true},{"title":"Large Flared \/ Raw Aluminum \/ Without","offer_id":46659404824765,"sku":null,"price":95.0,"currency_code":"USD","in_stock":true},{"title":"Large Flared \/ Raw Aluminum \/ With","offer_id":46659404857533,"sku":null,"price":95.0,"currency_code":"USD","in_stock":true},{"title":"Large Flared \/ Black Powdercoat \/ Without","offer_id":46659404890301,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true},{"title":"Large Flared \/ Black Powdercoat \/ With","offer_id":46659404923069,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true},{"title":"Large Notched \/ Raw Aluminum \/ Without","offer_id":46659404955837,"sku":null,"price":95.0,"currency_code":"USD","in_stock":true},{"title":"Large Notched \/ Raw Aluminum \/ With","offer_id":46659404988605,"sku":null,"price":95.0,"currency_code":"USD","in_stock":true},{"title":"Large Notched \/ Black Powdercoat \/ Without","offer_id":46659405021373,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true},{"title":"Large Notched \/ Black Powdercoat \/ With","offer_id":46659405054141,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1669\/8301\/files\/E096433B-CA4D-455D-A912-5EEB4AB48878.jpg?v=1778249253","url":"https:\/\/www-fms.myshopify.com\/products\/cavitation-plate","provider":"FMS","version":"1.0","type":"link"}
