The Powertow uses a back side idler pulley to control the speed by tightening the pulley against the belt.
The clutch handle is located at the top of the Powertow handle. When squeezed, it engages the pulley and
movement begins. When handle is released the pulley moves away from the belt and movement stops.
Belt guides are installed for proper belt disengagement.

Quicksilver Transmission Model 3500
Under proper operating conditions, the Quick Silver Transmission can be shifted by using only a fingertip
pressure on the shift lever. However, when a transmission is subject to even partial load from the engine,
the engaging lugs of the clutch collar and gears are forced together. Under this condition, the force required
to shift is multiplied. If enough force is applied, it may cause breakage of the shifter mechanism.
ADEQUATE DECLUTCHING - The transmission must be relieved of any load before shifting. The one
exception to this is in operating the clutch handle briefly, as a hunting action to permit the clutch collar lugs
and gear cavities to line up and mesh fully. If shift rod does not fall into gear easily,
engage clutch handle momentarily. This will allow the gears to fall into place
without binding the transmission.
LUBRICATION -
Quick Silver transmissions are
lubricated at the factory with special,
high quality grease. Under normal
operation, factory lubrication is
adequate for the life of the
transmission. Replenishment
is not necessary unless
the unit is disassembled.
