Are V-Drives and Velvet Drives the same thing?

Actually, not true in all cases. I have a '76 Silverton with v-drive, in
my
case the engine block is mounted to a Borg Warner Velvet Drive tranny,
which
is then bolted to the Walter V-drive gearbox. My Velvet drive is 1:1, my
Walter V-drive gear box is a model 10 with 1.5:1.
Next, the poster that said that a Borg Warner Velvet Drive is available in
stright or V-drive is correct. It IS available in various straight and
V-drive configurations, with different "V" angles and gear ratios. The
V-drive configuration is one sealed unit. The V-drive configuration isn't
as
common as the straight drive.
You are correct in that most boat manufactures that use V-drives do so to
keep the engines below the cockpit deck, thus allowing for more room in
the
cabin.

I believe the Borg-Warner "Velvet Drive" trademark can be a straight
or
a V configuration.
They made both.
The "V drive" component is completely separate from the transmission.
You
still
need a gear box to select FNR, and I don't know why you couldn't use
just
about
any mfgrs tran. The straight shaft running from forward facing tranny
couples
to the "V" drive assembly. The V drive is 1:1, so no additional
calculating is
involved when considering reduction rations in the main gearbox.
Not uncommon for the stern tube to be directly *below* the engine on a V
drive
configuration, allowing the engine(s) to be farther aft than on a
straight
inboard.
Most V drives are used to move the engine to the back of the boat for more
room. Most of the V drives were in ski boats. Heck, we used to call them
Vee drive boats. We had a Mandella, with a velvet drive and transmission in
one unit. Lots of the Vee drives just had an in/out box and some were
direct drive. Ready to ski, fire up the motor!
