Step 3:
Re-install the drain plugs or petcocks on
each side of the engine block. EFI engines have a
knock sensor located in one or both of the drain holes.
This/these unit(s) must be re-installed in the drain
hole(s).
Carefully install this unit without any additional
thread sealant. Be careful to avoid over-tightening this
unit. Torque specifications for installation of the knock
sensor is 14-16-ft-lbs.
Step 4:
Re-attach the large diameter hose to the water
circulation pump.
Step 5:
Re-install the transmission cooler hose connection.
Step 6:
Install the raw water impeller and reconnect
the hoses to the raw water pump. Use a new gasket,
even if the one removed at winterization time appeared
in good condition.
Step 7:
Install new spark plugs.
Step 8; If applicable, reconnect the hoses to your heat-
er or shower.
Step 9:
Check the engine compartment and bilge for
signs of nesting animals. Clean as necessary.
Step 10:
Check the condition of the distributor cap and
rotor (where applicable). Replace if either shows signs of
wear, damage or corrosion.
Step 11:
Check the entire engine system for fluid, oil and
coolant levels. Add as necessary.
Step 12:
Check the entire engine for cracks or leaks
caused by freeze damage.
Step 13:
Check all hose clamps for tightness. Install the
bilge drain plug and the rear drain plug in boats equipped
with certain types of ballast systems.
Step 14:
Grease the propeller shaft taper and install the
propeller.
Step 15:
Perform the daily maintenance as noted previ-
ously in this Owner’s Manual. If it was not done prior to
storage, perform the annual maintenance as well.
Step 16:
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.
Step 17:
Check the alignment between the output flange
on the transmission and the propeller shaft flange. If the
maximum feeler gauge that can clip between the flange
faces at any point is 0.003”, the unit is properly aligned. If
a thicker gauge can be inserted at any point, the engine
must be re-adjusted until proper alignment is obtained.
This should be performed by an authorized MasterCraft
dealer’s service department.
Step 18:
For all models, with the boat in the water, cycle
the key ON and then OFF two (2) or three (3) times, al-
lowing ten (10) seconds between key cycles, before
cranking the engine. This allows the fuel pump to prime
the fuel lines; then start the engine. In the event the en-
gine 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 read
-
ings 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.
Step 19:
In ProStar 197s equipped with ballast bags,
when reconnecting the hook-ups, be sure to squeeze the
prongs to help slide the connector back on. Dish soap or
some similar product will help slide the connects back
together. Note that the red ring goes over the raised ring
to ensure a working connection.
