Tohatsu Gasket 3RS-01303-0
Genuine Replacement Engine Basement Gasket
The 3RS-01303-0 Engine Basement Gasket is a critical sealing component for Tohatsu 4-stroke outboard motors. Positioned between the engine powerhead and the drive shaft housing (also known as the engine holder or basement), this gasket ensures a vacuum-tight and leak-proof connection, preventing exhaust gases and cooling water from escaping the intended internal channels.
