324453 OMC SPACER EXHAUST

OEM OMC Johnson/Evinrude 324453 nylon spacer for exhaust housing used on 25-35 HP outboard motors. Provides thermal and mechanical isolation between exhaust tube and engine block, preventing heat transfer and vibration noise. Lightweight nylon construction typical of 1980s-1990s OMC design. Replace when cracked or degraded; critical for proper cooling and exhaust function on these horsepower classes.
