Information
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.

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.
