Product 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.

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

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.
