If a "blower" is defined by you as a turbo (i.e. .., device to increase
air flow into the cylinders), then you are in error. I know several
people with 2 stroke DD 6-71's. Some are naturally aspirated, some have
turbos (blowers).

Richard,
All 2 stroke DD series whether inline or V configuration 71- 53's- 92's
even the old 110's etc.. have blowers, Naturally aspirated (NA) or
turbocharged (TI) . The 6v53 in my boat is a NA with a blower. UD
