G - 2 STEERINGLOAD
A load is placed on the steering system by the propeller
torque, and/or water flowing past the rudder. The steer-
ing system is designed to normalize the effort required to

consists of a gauge on the dash and an electrical send-
ing unit connected to a rudder tiller arm or the steering
assembly. See Figures G2 & G3.
Steering effort can vary significantly with engine
acceleration, steering angle, trim angle, and sea
condition. Be prepared for additional steering
loads at all times.
The reading on the gauge can be adjusted by loosening
the three screws securing the electrical sending unit and
turning the sending unit either clockwise and counter-
clockwise slightly. The reading will vary accordingly.

RUDDER
The 378’s dual v-drives have two rudders. These are
coupled together at the tiller arms by a tie bar. The rud-
ders are toed-in at the front to provide maximum stability
on straight ahead runs and proper tracking through cor-
ners. Rudder alignment is preset at the Four Winns
factory. Further alignment adjustments should not be
necessary unless the rudder or steering system incurs
damage. See Figures G2, G3, & G4.
