Universal Diesels are now being shipped with heavy duty transmissions.

The standard transmission on the Universal M3-20B and M-25XPB is being changed from the ZF5M to the ZF10M. The change increases the length of the unit by less than 1". The standard ratio (2.05:1) remains unchanged. This change is effective on engines manufactured at Westerbeke beginning August 1, 2007.
