Why Replace It, Engine mounts are crucial for:
•  Locating and supporting the engine
•   Absorbing vibration and engine torque under acceleration, braking, and cornering
•   When this mount deteriorates or fails, you can expect, Increased vibration transmitted to the cabin, steering, or pedals
•   Clunks, bangs, or loud noises during acceleration, deceleration, or gear changes from engine movement against the chassis
•   Visual signs such as leaking black fluid from the mount, sagging of tailpipes (due to dropped mounting), or visible damage to rubber or metal components 

Common Failure Causes:
•   Age-related rubber degradation: over time, rubber hardens, cracks or de-bonds, causing loss of damping and allowing engine movement
•   Fluid leakage (hydraulic version): loss of damping fluid due to seal failure accelerates failure
•   Fluid contamination: oil, coolant, or other contaminants degrade the rubber material
•   Vehicle abuse or stress: aggressive driving, hard launches, or previous accidents can warp or break mounts
•   Worn or cracked brackets: even if the rubber is intact, the aluminium bracket can be damaged or corroded, reducing effectiveness

Engine mount Part number 987.375.023.05 (often written 98737502305) is the centre engine mount / mount insulator used on mid-engine Porsche Boxster/Cayman models, commonly fitted to late 986 and 987 Boxster / early 987 Cayman applications. The item is offered both as the complete mount and bracket assembly and as a replacement bushing/insulator that must be pressed into the aluminium bracket.

Position: center engine mount (the central mount that locates the engine fore/aft and resists torque). 

Fits:

• Porsche Boxster 986 2.5L 1997-99
• Porsche Boxster 986 2.7L 1999-02
• Porsche Boxster S 986 3.2L 1999-02
• Porsche Boxster 986 2.7L 2003-04
• Porsche Boxster S 986 3.2L 2003-04
• Porsche Boxster 987 2.7L 2005 -08/08
• Porsche Boxster 987 S 3.2/3.4L 2005-08/08
• Porsche Cayman 2.7L 987C 2006-08
• Porsche Cayman S 3.4L 987C 2005-08  

Replace the part when it has lost its ability to control engine movement and damp vibration. Typical triggers to replace the centre mount include: 

• Hard clunk or bang on acceleration, deceleration or gear changes (engine shifting against chassis).
• Excessive vibration into the cabin, especially at idle or specific RPM bands.
• Visible damage — torn, separated rubber, oil-soaked or collapsed mount/bushing, or corrosion of mating faces. 

Common issues & failure causes

• Rubber deterioration: age, heat cycling and mechanical fatigue cause the rubber to harden, crack or de-bond from the metal, reducing isolation and allowing increased engine movement.
• Fluid contamination: oil or coolant leaks accelerate rubber breakdown (softening or swelling), commonly seen on older engines where leaks occur.
• Mechanical shock / abuse: repeated hard launches, aggressive shifting or collisions can cause sudden mount failure or promote early fatigue.
• Bracket wear / corrosion: the bushing may be fine, but the aluminium bracket can crack, corrode, or the bushing may need pressing into a worn bracket — which is why some techs prefer replacing the full assembly.
