SEA-DOO RXP-X 300 Carbon Seal Overheating

Carbon Seal Rebuild Kit

The carbon seal is a mechanical face seal that requires water for lubrication and thermal dissipation. Overheating occurs when friction between the stationary carbon ring and the rotating stainless steel collar generates excessive heat, usually during dry-land operation. This kit replaces the carbon ring, bellows, and retaining clips to restore the watertight interface and tension.

Stainless Steel Drive Pipe Collar

When a carbon seal overheats, the stainless steel 'hat' or collar often suffers from surface scoring or heat-induced warping. If this surface is not perfectly smooth, the new carbon ring will fail prematurely due to abrasive wear. Replacing the collar ensures a flat, polished mating surface for the mechanical seal.

Drive Shaft C-Clip

This small retaining clip holds the stainless steel collar in place against the pressure of the bellows. During an overheat event, the clip can lose its temper (spring tension) or become brittle, leading to a catastrophic failure where the seal slides down the shaft and allows the hull to flood.
