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.
PROPELLER MAINTENANCE
Propeller damage is caused by striking solid objects. If the propeller
is not rotating at the time it strikes a solid object, the damage is
usually confined to just one blade and may be difficult to see. If the
propeller is rotating when it strikes an object, usually the resulting
damage can easily be seen on all blades.
CHECKING/REPAIRING
PROPELLERS
Step 1
Ensure the engine is OFF and the emergency safety stop switch is
disconnected.
Step 2
Clamp a small rule scale to the shaft strut, parallel to the shaft so
that the end of the scale is 3/32-inches from the leading edge of a
propeller blade.
Step 11
Fully recharge and reinstall the battery or batteries.
Step 12
Perform the daily maintenance as noted previously in this Owner’s
Manual. If it was not done prior to storage, perform the annual main-
tenance as well.
Step 13
If the boat is equipped with the optional fresh water cooling system
and was drained for storage, fill the system with fresh coolant solu-
tion per instructions.
Step 14
Check the alignment between the output flange on the transmis-
sion 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 readjusted until proper alignment is
obtained. This should be performed by an authorized MasterCraft
dealer’s service department.
Step 15
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; then start the engine. In the event the engine
does not respond, allow a two-minute cool-down period for every
