Got a Yamaha outboard with trim issues? This piston seal and back-up ring might fix it! Specifically made for Yamaha trim cylinders, it replaces part numbers 6E5-43864-00-00 and 6E5-43874-01-00. When your trim isn't holding pressure or leaks fluid, worn seals are usually the culprit. This SKD brand replacement is made in Taiwan to proper specifications. Installation requires some mechanical know-how - you'll need to disassemble your trim cylinder - but it's much cheaper than buying a whole new unit. No warranty is offered (typical for small parts like this), but it's a quality replacement. Note the Prop 65 warning about chemicals (standard for many mechanical parts). Perfect for boat owners, marine mechanics, or anyone looking to fix their Yamaha outboard's trim system themselves. Get your boat trimming smoothly again without breaking the bank!
