0434632 Evinrude Johnson Mount Assembly-Rubber | Genuine OEM BRP Outboard Part

🔧 Product Description

Genuine BRP Evinrude Johnson Lower Rubber Engine Mount Assembly - Part Number: 0434632

A genuine BRP lower rubber engine-mount assembly for selected Evinrude and Johnson 75HP-300HP outboards.

The mount is installed between the exhaust housing and the steering or swivel-bracket structure. Its bonded rubber-and-metal construction controls engine movement while isolating normal powerhead vibration and absorbing propulsion loads, gear-selection shock and impacts transmitted through the lower unit.

Most compatible installations use two lower mounts, with one fitted to each side of the exhaust housing.

🔌 Function

The lower mounts connect the exhaust housing to the swivel-bracket structure while allowing controlled rubber movement.

They help:

• Maintain powerhead and gearcase alignment

• Limit excessive engine movement during acceleration

• Absorb shock when forward or reverse gear is selected

• Reduce vibration transferred into the transom

• Stabilise steering response

• Protect the exhaust housing and mounting brackets from impact loads

Common signs of mount failure:

• Excessive engine movement inside the swivel bracket

• Clunk during acceleration or deceleration

• Engine shifts noticeably when selecting gear

• Steering feels loose or inconsistent

• Rubber separates from the metal plates

• Rubber is cracked, swollen or compressed

• Lower mount covers are damaged

• Mounting screws loosen or corrode

• Exhaust housing sits unevenly

• Increased vibration is transmitted to the boat

• Propeller thrust causes visible midsection movement

Installation considerations:

• Support the outboard securely before removing mount hardware

• Inspect both lower mounts and the upper mount

• Replace lower mounts as a matched pair where practical

• Check the mount covers for cracks or corrosion

• Inspect mounting screws, washers and threaded holes

• Remove corrosion and scale from the mount pockets

• Do not damage the bonded rubber during installation

• Do not apply petroleum-based lubricant to the rubber

• Use the specified marine corrosion protection on approved metal surfaces

• Follow the correct tightening sequence and torque specifications

• Confirm unrestricted steering and tilt movement after installation

• Recheck engine movement before returning the boat to service
