Just a little info about it but these are from Volvo IPS drives that have been out on the market for 10 years. Same concept and theory.

Its basically can be sort of like auto's with front wheel drive pulling the car forward compared to rear wheel drive pushing the car forward.

I have ridden in a barefoot boat with a stock dp drive f3 props that would practically rip a slalum skiier right out ofthier bindings and still run mid 70's . my ski pro with a mild vortec was still a stout peeformer and could be ballasted and trimmed halfway out and never missed a beat .other than a brutal rough water ride was a very fun boat .ill be watching vp on this one sounds very interesting.

This has been around for years
My dad had a boat in the late sixties early seventies with this type of drive.
I think it was an Italian design.

who has an idea of how much a normal duo prop compares to a forward facing drivee

One out performs the other.
Forward facing has less prop slip and rear facing is more efficient in top speed

R U asking about price differences between the 2 ?

yes sorry i was asking price. didn't pay attention to what i was typing.

Looks cool, Volvo has had some amazing drives over the years... I wonder how this would work in a bracket racing situation? Our One Desing boats love duoprops.

I doubt it would be too good for racing, to clear the props that has to be a deep drive I would suspect...

I do not know the price of the new Volvo fwd facing drive.. I do know its uses the exact same upper as the current drive so that price of just the upper is the same. (The outdrive that has been out since 2007 / 2008) - Volvo changed their drive designs and transom assemblies for model year 2007 for both the SX and the DP = duoprop.

They (SX & DP) are both 1 to 2 mph faster hydrodynamically plus use a intergrated speedo pitot like what mercruiser has been for years.
