It's especially valuable when the fill plug is recessed or surrounded by tight engine cowling, making a straight-tube application messy or impractical.

The 28401 is the correct call for Yamaha and Tohatsu owners, which represent a large share of the recreational outboard market. Thread mismatch is the most common customer error with these fittings; always prompt customers to confirm thread pitch in their owner's manual. Strong add-on sell alongside any gear lube squeeze tube purchase for Japanese-brand outboard customers.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199661080612,"sku":"74-28401","price":18.39,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/74-28401.jpg?v=1785611263","url":"https:\/\/marisolmarine.com\/products\/star-brite-28401-lower-unit-gear-lube-adapter-fitting","provider":"Marisol Marine Company","version":"1.0","type":"link"}
