Engineered to accept a 1\/2\" socket drive, it pairs with breaker bars, torque wrenches and impact tools for fast, reliable service. The kit includes six spare L-4 pins and is manufactured from corrosion-resistant stainless steel with a proprietary heat treatment for higher yield strength.\u003c\/p\u003e\n\n\u003ch3\u003eWill this wrench fit my Yamaha or similar outboard trim caps?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the AMT0306 matches the Yamaha 32mm trim cap profile and uses 4mm L-4 pins that engage standard trim cap holes. It’s listed as a direct replacement for Yamaha part numbers YB-06175-1A, YB-06175-2B, and YB-06548, and is compatible with many Honda, Suzuki, Johnson, and Evinrude trim caps that follow the same pin pattern.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFits 32mm trim cap nut with 4mm L-4 pin holes.\u003c\/li\u003e\n  \u003cli\u003eReplaces Yamaha YB-06175-1A, YB-06175-2B, YB-06548.\u003c\/li\u003e\n  \u003cli\u003eWorks on many Honda, Suzuki, Johnson, and Evinrude models using the same pin spacing.\u003c\/li\u003e\n  \u003cli\u003eIncludes six spare L-4 replacement pins (AMT0050 compatible).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the lock-in sleeve-and-receiver system prevent the wrench from slipping?\u003c\/h3\u003e\n\n\u003cp\u003eThe wrench is designed to accept the AMT0170 sleeve (sold separately) which seats into the trim housing and creates a stable receiver for the spanner.

The AMT0306 is built for boat owners, professional mechanics, and marine technicians who service Yamaha-style outboards and need a robust, corrosion-resistant spanner that pairs with standard 1\/2\" drive tools. It’s ideal for anyone who wants a durable aftermarket replacement for OEM part numbers, a tool that withstands higher torque without pin failure, and a product backed by a lifetime warranty from a small family-owned marine tools company.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the AMT0306 fit non-Yamaha outboards?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it fits many Honda, Suzuki, Johnson, and Evinrude trim caps that use the same 32mm x 4mm L-4 pin pattern.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the AMT0306 safe to use with a torque wrench?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes; the 1\/2\" drive accepts torque wrenches and the pins are rated to a minimum 200 ft-lb yield.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"M Marine Tech Tools","offers":[{"title":"Default Title","offer_id":48030576279713,"sku":"B017KTYA86","price":157.12,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0758\/6532\/5729\/files\/marine-tech-tools-amt0306-front-view.jpg?v=1791406597","url":"https:\/\/canadiansporting.ca\/products\/marine-tech-tools-32mm-yamaha-outboard-trim-spanner-wrench","provider":"Canadian Sporting","version":"1.0","type":"link"}
