Default
Value
Toe Angle
Sets the static toe angle of the
engines. A positive value will toe
the engines out (gear cases farther
apart at front edge).
-5 to 5
0
Inner/Outer Steering
Ratio
Similar to Ackerman compensation
on road vehicles, this parameter can
make the inner engine turn more
than the outer engine in a turn. The
higher the value, the less the outer
engine will turn. e.g. A value of 2.0
will deliver 15 degrees of steering
at the outer engine when the inner
engine is steered at 30 degrees.

Typically the RPM at which the boat
begins to plane. See figure 7-12

High Speed Engine RPM Sets the engine RPM that marks
the lower boundary of high speed.
Typically close to maximum RPM.

is running at low speed. The value
is a percentage of maximum effort
(steering locked).
