Notes:
1 The Troll range of engine idle RPM adjust-
ment available for both RPM and speed mode
depends on engine type. Generally this is
between 600 and 1000 RPM.
2 In speed troll control, the boat might not
reach the desired speed if the maximum RPM
available for troll control is too low or if condi-
tions are bad.
3 Troll can not engage unless engine throttle(s)
are in idle, and engine(s) are in gear.
4 Troll control is not available on some Mer-
Crusier
TM
engines.
5 To use speed troll control, the Navman instru-
ment must have a Navman paddlewheel
speed sensor connected.
