the throttles so that the engines are running the same RPM (synchronized) can be done by listening
to the engine sounds, or with an engine synchronizer. Attempting to synchronize the engines solely
by using the tachometer readings or control lever placement generally will not work. When the
engines are in proper synchronization, the throttle levers may not necessarily be even. Please refer
to the engine or control manual for more information on the controls installed on your boat.
2.3 Engine Synchronizer (Optional)
Your boat could be equipped with an engine synchronizing system. When the system is on, the
synchronizer monitors the RPM of each engine and automatically keeps them at the same RPM.
When the system is turned off, the unit has no effect on the normal manual throttle operation.
Synchronizers vary in operation from different manufacturers, but generally, the system is activated
and deactivated by a switch at the helm. When the synchronizer is on, one master throttle will
control the RPM of both engines. Engine synchronizers require specific procedures for engage-
ment and disengagement of the system that must be performed in the proper sequence.
The engine synchronizer manufacturer provides an owner’s manual with its product. It is
extremely important that you read the manual and become familiar with the proper care and
operation of the synchronizer before using it with your boat.
2.4 Neutral Safety Switch
Every control system has a neutral safety switch. This device prohibits the engine from being
started while the shift lever is in any position other than the neutral position. If the engine will not
start, slight movement of the shift lever may be necessary to locate the neutral position and
disengage the safety cutout switch. Control or cable adjustments may be required to correct this
condition, should it persist. See your Pursuit dealer for necessary control and cable adjustments.
The neutral safety switch should be tested periodically to insure that it is operating properly. To
test the neutral safety switch, move the shift levers to the forward position. Make sure the throttle
levers are set to the idle position. Activate the starter button for each engine. The starter should
not engage for either engine. Repeat this test with the shift levers in reverse and the engine throttles
at idle. Again the starter should not engage for either engine. If the starter for either engine engages
with the shift controls in any position other than the neutral position, then the neutral safety switch
is not functioning properly and you should contact your dealer and have the neutral safety switch
repaired before using your boat. If an engine starts in gear during this test, immediately move the
shift levers to the neutral position. Turn the engines off and have the problem corrected by a
qualified marine mechanic before using the boat.
