This heavy‑duty aftermarket crankshaft labyrinth serves as a reliable drop‑in replacement for Tohatsu and Nissan 9.9HP, 15HP and 18HP two‑stroke and four‑stroke marine outboard motors. It matches OEM part numbers 350‑00051‑1 and 350‑00051‑0.
It is precision‑machined from high‑strength steel material. This labyrinth sealing component delivers outstanding wear‑resistance, stable structural rigidity and reliable anti‑corrosion performance for long‑term crankshaft operating conditions inside the marine crankcase.
It builds an effective labyrinth sealing structure around the crankshaft shaft journal. It restrains oil blow‑by, prevents crankcase oil leakage and stops outside moisture and dust from invading the crankcase while the outboard runs under tough boating surroundings.
This labyrinth part is CNC‑processed following original OEM specifications, so it maintains precise fitting clearance and stable sealing effect during high‑speed crankshaft rotation. It resolves common crankcase troubles including oil seepage, excessive oil consumption and contaminated crankcase caused by worn‑out original labyrinth components.
All critical dimensions comply with OEM standards. You can complete quick, straightforward drop‑in installation, and no trimming or extra adjustments are needed. Remove burrs and clean mating surfaces thoroughly before fitting. Avoid scratching the labyrinth sealing surface during assembly.
Swap your deformed, worn or damaged factory crankshaft labyrinth with this spare component, and you will restore dependable crankcase sealing performance for your outboard. Follow regular marine maintenance schedules. These good practices extend engine service life and sustain stable engine running out on the water.
