Thanks guys. Now do the motor mounts wear out over time or usage. Car has just under 50k.

Time ravages the rubber. If it hasn't been replaced yet it likily that it needs to be. Warehouse 33 got it for $174.

I changed mine earlier this year when I did the water pump and other items. The Boxster had 26,000 miles on it. Here are some photos of it. Keep in mind the car is a garage queen, it is always in the garage and never driven in the rain. Like others have said, it's the age. Fourteen year old rubber under stress just doesn't hold up.

The part number is 987.375.023.05. It was $138.62 at Sunset Porsche.

This is a side question - but can changing the motor mount effect the stick shift and how hard it is to shift?

I had my clutch done in Oct 2014 and afterwards my shifter was the smoothest ever. Then in Dec 2014 I did the motor mount and I don't remember the timing exactly but for the last year shifting has been tight and hard. I also had the transmission fluid changed somewhere in that time frame.

What fluid was used? Probably not Porsche OE 75W90 gear lube. Go back to that, and it should improve. Worse on cold mornings?

Motor mounts on a Boxster are more critical for the trans vs a 911 (a 911 actually has trans mounts too) due to the mid engine set-up.
