In its first
test, our new propeller with variable pitch was proved as effective as a
standard propeller.

ProPulse
has every prospect of becoming an international seller. Our first variable
pitch propeller is as effective as a standard propeller - and that’s more
than sufficient cause to recommend it.
There is an endless list of compelling arguments in favour of ProPulse.
Being able to adjust the pitch means that the boat can be driven at its
optimum capacity, whatever the load. Furthermore, for the first time ever,
the driver has a choice: lowering the pitch by a couple of inches brings
down the maximum speed by a knot or so, but dramatically speeds up
acceleration - and vice versa. ProPulse has replaceable blades, extremely
useful after a boat goes aground.
Paying $56 for a new blade is a good deal cheaper than buying a new
propeller. The propeller is made of a non-corrosive composite that is
stronger than aluminium. It also weighs less than aluminium, although this
may not make a difference to the ordinary boat owner. |
