0331353 Evinrude Johnson O-Ring | Genuine OEM BRP Outboard Part

🔧 Product Description

Genuine BRP Evinrude Johnson Impeller Housing-to-Plate Seal - Part Number: 0331353

A genuine BRP moulded seal installed between the water-pump impeller housing and its underlying plate on selected large Evinrude and Johnson gearcases.

Although commonly described as an O-ring, BRP catalogues identify 0331353 specifically as the impeller-housing-to-plate seal.

It prevents pump pressure from escaping between the housing and plate and helps ensure that cooling water is directed into the water tube.

Important fitment note:

• This seal is not the paper water-pump gasket.

• It must be positioned in the correct groove between the housing and plate.

• Twisting, stretching or pinching the seal can cause immediate loss of pump pressure.

🔌 Function

The seal closes the joint between the pump housing and plate so the impeller can develop sufficient suction and outlet pressure.

Common signs of seal failure:

• Weak tell-tale flow

• Engine overheats

• Pump will not prime

• Seal is flattened or split

• Rubber is hardened

• Water leaks around the pump housing

• Housing is distorted

• Cooling performance remains poor despite a new impeller

Installation considerations:

• Clean the seal groove

• Inspect the housing and plate for corrosion

• Replace a distorted pump housing

• Lubricate the seal only with an approved assembly product

• Do not use excessive sealant

• Ensure the seal remains fully seated

• Tighten the pump housing evenly

• Confirm water flow after reassembly
