immediate assistance as the engine cooling system will likely require purging. This
function should be completed only by a trained ILMOR service technician.
Failure to maintain your coolant at the proper level will cause potentially serious
engine damage. The warranty does not cover engine damage due to overheating or
any other cause associated with improper coolant levels.
Because this process should be completed while the engine is cool (in order to avoid burns), it is
recommended that this check be completed prior to starting the engine. On engines with serpentine belt
systems, however, no change is necessary. Belt tension is maintained by the automatic belt tensioner.
• Ensure the engine is OFF and the engine safety starting switch
is disconnected. Leave the throttle/shift control lever in neutral.
Open the engine compartment and locate the alternator belt.
• Checkthealternatorbelttensionatthetop,midwaybetweenthe
circulating pump pulley and the alternator pulley. The belt should
be tight enough so that it will deflect no more than one-quarter to
one-half inch when pressed with the thumb or finger.
Note: if the belt is too tight, excessive belt and bearing wear can
occur. If the belt is too loose, slippage can occur, resulting in low
alternator output and rapid belt wear.

of excessive wear, cuts or weakness across or in the grooves. If there are any signs, have
the belt replaced.

Leave the throttle/shift control lever in neutral. Locate the battery(ies). Bat-
teries are placed in a variety of locations, depending upon the model. Refer
to the boat manufacturer’s Owner’s Manual for details. In most instances, the
battery(ies) will be under the observer’s seat or behind one of the rear seats.

remove the negative terminal connection first. Be careful to avoid touching
the positive terminal with the wrench or negative connection. Then loosen
and remove the positive terminal connection. Remove the battery hold-downs
