Specifications

Battery electrolyte fluid is dangerous. It contains sulfuric acid, which is
poisonous, corrosive and caustic. If electrolyte is spilled or placed on
any part of the human body, immediately flush the area with large
amounts of clean water and seek medical aid.
• Use a battery terminal cleaning brush to remove corrosion from the inside of the battery terminals. Clean the terminals
with a water-and-baking-soda solution and rinse.
• Reconnect the positive terminal first, then the negative. Tighten the terminals. Coat both terminals completely with a thin
covering of marine grease. Be sure that the rubber boot covers the positive terminal completely.
Note: Your engine is designed to work with the standard electronics installed in your boat. If you add other electrical
components or acccessories, you could change the way the fuel injection controls your engine or the overall electrical system
functions. Before adding electrical equipment, consult your dealer. If you don’t, your engine may not perform properly.
Add-on equipment may adversely affect the alternator output or
overload the electrical system. Any damage caused as a result will not
be covered by, and may void, your warranty.
If you ever need a replacement battery, be certain to select a marine battery with at least 750 cold-cranking amps at
zero degrees Fahrenheit. Before disconnecting the battery, make sure the ignition key and all accessories are in the OFF
position. Also remember to re-attach the cables correctly, with the negative cable connected to the negative or (-) post and
the positive cable connected to the positive or (+) post.
When charging, batteries generate small amounts of dangerous
hydrogen gas. This gas is highly explosive. Keep all sparks, flames and
smoking well away from the area. Failure to follow instructions when
charging a battery can cause an electrical charge or even an explosion
of the battery which could cause serious injury or death
MasterCraft recommends the use of a spiral cell type battery, such as the Optima brand. These batteries exceed most
other batteries in holding and extending a charge.
INSPECT THE ENGINE FOR LOOSE
OR MISSING HARDWARE
Because this process should be completed while
the engine is cool and cannot cause burns to your
skin, we recommend you do this before starting
your boat.
Step 1: Ensure the engine is OFF and the engine
safety starting switch disconnected. Be certain that
the throttle/shift control lever is in neutral. Open the
engine compartment and visually inspect the engine.
Step 2: Systematically check the entire engine for
loose and missing hardware. Try to shake compo-
nents by hand such as the alternator and the
motor mounts. If a looseness problem exists, see
your MasterCraft dealer.
