the closest consensus I found from reading around is to replace the WP as a preventive measure, regardless of symptoms every 60K miles

I agree and just had mine replaced at 62k. My water pump was good but did it for preventive maintenance. Also the 997 water pump is now spec'ed for the 996 replacement. I had it done at RUF and that's what they put in.

Well, once again I think I'm on the opposite side.
What I have found works for me is to replace the water pump when it needs it.
Now I have not owned a 996 and may be these cars go through water pumps like crazy but I have an 02 Boxster and its original water pump lasted over 170K miles. I have put another 80K miles on the replacement water pump (factory pump) and it seems to be working just fine.
My 03 Turbo has just over 86K miles and its original water pump is working just fine too.
If I followed the recommended replacement intervals for water pumps, starters, clutches, alternators, and god only knows what else, I would have spent a fortune unnecessarily on my cars. (I have for instance a set of spare serpentine belt idler rollers and tensioner for my Boxster. Bought these years ago. I have not had to take then out of their baggies.)
And there's no guarantee the new part will prove to be ok. That's why Porsche offers a 2 year parts warranty on new parts.
Sincerely,
Macster.

As usual, I'm with Macster. I replaced mine at 110k miles when it needed it. I ordered the pump from a dealer and the part I received had metal impellers. I know plenty of people have received plastic.

The PO had the pump replaced at 80k miles as a preventative measure. The replacement failed at 116K. The part appeared to be an aftermarket one, although it was hard to tell. I purchased a new pump from Sunset for $222 last fall.
If my engine makes it to 160k or about 45k miles on the pump, that is when I plan on changing it out. It isn't worth 200 bucks to get stranded.
Now it is time to change out the original coolant reservoir and cap. I can't believe they have lasted this long!

BEST CASE SCENARIO: car gives enough "warnings" or symptoms that WP is about to crap out so owner is able to fix/repair.
I have read about some owners who had ZERO warnings (or maybe some ignored the clues or were simply CLUEless) who then had to deal with a catastrophic failure.
I am leaning towards taking a vigilant/wait-and-see stance like Macster above (have 63K miles on original WP: no noises, drips or wiggle/jiggle so far)

70K on my Turbo with no signs of trouble. How hard is it to change or is it one of those things it best to just have someone else do it?

Mine just failed at the impeller shaft, leaking water onto the garage floor overnight. My car, a MY2000 model had 132,000 miles on it when that happened, and it was an original pump. When I pulled it, the plastic vanes were perfect. No signs of any wear at all. I replaced it with another Porsche water pump.

Waterpump replacement is somewhat north of $1000 so, no, this is really not a "maintenance" item. Unfortunately, just like with every other car, the waterpump WILL fail at the most inopportune time and leave you stranded. In the middle of South Carolina. On a Sunday. OK, maybe that was just me ... but still.

The water pump in my Boxster failed, or that is I noticed the noise and diagnosed it to a probable water pump problem in my parking space. Had the car flat bedded to Walnut Creek Porsche dealer for water pump R&R.
The fuel pump quit at the same location. I started the engine and backed the car up about half a car length out of the parking space then the engine died. It almost restarted but then nothing. Had the car flat bedded to Livermore Porsche and after diagnosis the fuel pump was R&R'd.
Oh, and the coolant tank too. I thought a radiator fan was not running so I pulled the car in to my parking space after a bit of drive around the neighborhood (to really get the engine up to temp) and after backing the car in and raising the rpms to cause the fans to switch on I got out of the car and determined the passenger side radiator fan was not running.
At this time I noticed on the pavement a trail of what proved to be coolant. Walking to the rear of the car to check the coolant level I spotted coolant pouring from the car.
In this case I waited until the car was completely cold then started the engine and drove the car the 2 or so miles to the Livermore Porsche dealer.
The only thing that has failed on the Boxster away from home is the 2nd AOS. It failed -- eventually -- 2K miles form home but thankfully just 90 miles from Aristocrat Motors in Merriam KS where I had the 1st AOS attended to when it failed (at home thought at that time home was in Oak Grove Mo).

Macster.
