Step 1 

Remove duct tape from exhaust flaps. 

Step 2 

Fully charge the battery(ies) and install them in the boat, following all safety precautions associated with changing batteries. 

CAUTION: Often, batteries that have been stored over winter will require recharging. Only an authorized battery charger should be used to charge the battery(ies) in MasterCraft boats. Use only a three-stage or more battery charger. It is important that the operator never turn a battery charger immediately to start, as the sudden jolt of voltage may cause damage to the electrical system, particularly the control modules for the ballast system. Regardless of the time of year, care should always be used when charging a battery(ies). 

Step 3 

Follow all instructions for reactivating the engine and drive train as detailed in the Ilmor Marine Engine Owners Manual. 

NOTE: Due to the complex nature of the engine and drive train re-activation process, MasterCraft recommends having an authorized MasterCraft or Ilmor Dealer perform this function. 

Step 4 

Ensure that all drain plugs throughout the boat and drive train have been reinstalled to avoid unwanted water intrusion. 

Step 5 

If applicable, reconnect and verify that all hoses to the heater, the head, the fresh water wash down, and the wet bar are in proper working condition with no leaks. 

Step 6 

Check the engine compartment and bilge for signs of nesting animals. Clean as necessary. 

Step 7 

Check the entire engine system for fluid, oil and coolant levels. Add as necessary. 

Step 8 

Check the entire engine for cracks or leaks caused by freeze damage. 

Step 9 

Check all hose clamps for tightness. Install the bilge drain plug and the rear drain plug (if applicable). 

Step 10 

Grease the propeller spline and install the propeller. 

Step 11 

Perform daily maintenance as noted previously in this Owners Manual. If it was not done prior to storage, perform annual maintenance as well. 

Step 12 

If the boat is equipped with the optional fresh water cooling system and was drained for storage, fill the system with fresh coolant solution per instructions in the Ilmor Engine Owners Manual. 

Step 13 

For all models, with the boat in the water, cycle the key ON and then OFF two (2) or three (3) times, allowing ten (10) seconds between key cycles, before cranking the engine. This allows the fuel pump to prime the fuel lines. Start the engine. In the event the engine does not respond, allow a two-minute cool-down period for every thirty (30) seconds of cranking. When the engine fires, keep a close watch over the gauge readings and check for leakage and abnormal noises. Keep speeds low for the first fifteen (15) minutes to allow the engine to reach normal operating temperatures
