[PCW] Power-Cats and the Volvo IPS or MerCruiser Zeus Drive systems

[Roger Bingham]

I appreciate what you are saying, Tim, but that the power output quoted
below are absolute terms.

What Volvo say is that because of the increased efficiency etc etc of the
IPS drive - their 260hp engine connected to an IPS drive equates to an
output of 350hp for an engine connected through a standard reduction gear.

Therefore a builder can use a lower rated IPS engine for the same/similar
performance envelope of a larger "standard" installation.

Their claim/explanation - not mine.
