IMPROS PRO-CONE
Improve pump efficiency
and increase performance!
The durable new Pro-Cone is a must-have with
the new high horsepower watercraft creating
extreme pump pressures. Rubber impeller cones
tear off creating an inefficient pump and performance loss.

WATCON IMPELLER PITCH GAUGES
It's a known fact; not all impellers are created equal. Sometimes when impellers are mass pro-
duced, there are subtle differences that can affect performance. Use this simple tool to measure
the pitch angle and blade length of each blade throughout its circumference. This enables you
to make adjustments to the pitch where needed. Great for fine tuning, making minor changes or
verifying pitch when sending impellers off for repair.
