The key is for safety and security. The key should be inserted prior to starting an outing, and removed at the conclusion. This is intended to prevent theft or unapproved use of the boat. Boats are equipped with an ignition key, which must be inserted in the ignition key slot and used to activate the boats electrical system. This, in turn, will allow the boat to be started and operated.
The key will be in one of two (2) positions:
ON (electrical power is ON)
The ignition key slot is located on the dash or drivers arm rest.
Insert the key into the key slot. Turn the key ON. Never start the engine without having first run the blower for at least four (4) minutes.
* Never leave the ignition switch in the ON position without the engine running, as this will cause the battery to discharge.
If the key will not turn after being inserted in the key slot, it is likely to be the wrong key. If the key turns but no electrical power occurs, check the voltmeter for a reading. If it is lower than 10.5 volts or does not register, the battery(ies) require recharging. Use only a MasterCraft battery charger.
DO NOT attempt to jump start the battery from a vehicle or another boat as this can cause an overload of the boats electrical system, resulting in significant damage to the boat that is not covered under the warranty. Attempting to jump start a battery or batteries on a MasterCraft boat, regardless of battery brand, from a vehicle or another boat can cause an overload to the boats electrical system, resulting in significant damage to the electrical system. This is not covered under warranty.
The START-STOP button is used to start the engine after the ignition key has been turned ON. The same START-STOP button turns the engine OFF.
The process for starting the boat is:
Insert the key and turn. (This turns ON the electrical system and prompts the battery(ies) to provide power.)
Turn the blower ON and allow it to run for at least four (4) minutes before starting the engine.
Momentarily press the engine START-STOP button.
When it is time to turn the engine OFF, press and hold for three (3) seconds the START-STOP button. If the button is held for less than three (3) seconds, the engine will not turn OFF. This is a system design to avoid shutting o the engine if the button is inadvertently pressed or hit during operation.
This button affects only the engine. The electrical system will continue to operate as long as the key is turned ON.
If the key is left turned in the ON position after the outing, it will eventually run down the battery(ies) and the engine and all systems will not start as a result.
At the conclusion of the outing, turn the key to the OFF position and remove from the key slot. Doing so will ensure that you have shut down the electrical system, and it will prevent others from starting or running the boat.
If the key switch is in the ON position and the engine will not start by pressing the START-STOP BUTTON, check the voltmeter for a read- ing. If it is lower than 10.5 volts or does not register, the battery(ies) require recharging. Use only a MasterCraft battery charger. DO NOT attempt to jump start the battery from a vehicle or another boat.
