We've been playing with the numbers and it looks like 5% fixed +
3% per thrust point.

Thrust	      2     4	   6
Drives
   1	      11%   17%   23% 
   2	      16%   22%   28%
   3	      ---   27%*  33%
   4	      ---   32%   38%**

*assumes one thrust 2 and 2 thrust 1s
** assumes two thrust 2s and 2 thrust 1s 

A single drive goes down when it fails a threshold.  You have no thrust.
If you have two drives and they both go down it would take two 
repair rolls to bring them back up.  If you have 3 drives and all
three go down then three repair rolls.	Your single drive destroyers
gain 7%, 2 or 3 mass, which is worthwhile.  Your two-drive bigger
ships lose a bit at thrust 4 and gain a bit at thrust 6.  The numbers
might still need to be tweeked.
