VETUS K-50/ double belt pullies

[Red]

Many skippers have replaced their engine mounts with Vetus K-50 soft mounts.  My question is if they are still happy with them?  Any input, reflections, advice, or tips will be appreciated.
 My second question is about double belt pullies for the crankshaft and water pump on an M-25XP with a high output alternator.  I read about the availabilty of both but I have misplaced the info.
  Thanks Russ Otto C-34 #505 "Fainche"

I replaced mine last month and I am extremely satisified. Just be sure to file out the elongated slots as much as possible to get a good engine alignment. The companion way and lockers that rattled very loudly are very quiet now.
