🔧 Product Description

Genuine BRP Evinrude Johnson Lower Rubber Engine Mount - Part Number: 0434629

A genuine BRP lower rubber engine-mount assembly for selected high-horsepower Evinrude and Johnson outboards.

Although the supplied title identifies a roller-and-sleeve assembly, OEM catalogues identify 0434629 as a lower rubber mount assembly.

🔌 Function

The mount controls powerhead and exhaust-housing movement while isolating normal engine vibration from the transom bracket.

Common signs of failure:

• Excessive engine movement

• Clunk during acceleration or deceleration

• Steering feels loose

• Rubber separates from the metal

• Engine sits unevenly in the swivel bracket

• Cracks or swelling in the rubber

• Propeller thrust causes abnormal housing movement

• Mounting bolts or bores are corroded

Installation considerations:

• Support the engine correctly

• Inspect both lower mounts and the upper mount

• Check mounting bolts, sleeves and bracket bores

• Remove corrosion from the mount pocket

• Do not apply petroleum grease to exposed rubber

• Tighten hardware to the specified torque

• Confirm unrestricted steering movement

📦 Condition

• Genuine BRP Evinrude Johnson OEM part

• Brand new

• Supplied in genuine or equivalent protective packaging
