Description
The Yamaha 90430-08003-00 is a genuine OEM lower unit gear oil drain/level screw gasket for Yamaha outboards.
Why it matters
A low cost seal that is worth renewing whenever the joint it seals is disturbed, rather than reusing an old one and chasing a weep later.
Fitting
Always fit new gaskets when changing lower unit gear oil. A reused or missing gasket lets water into the gearcase.
