Propeller Shaft Alignment
The propeller shaft coupling and the transmission coupling should be
checked for proper alignment beginning with the first launching, again
after 20 hours of engine operation, and annually thereafter. The
alignment should especially be checked if noise or vibration occurs.
Excessive vibration, abnormal strut bearing wear, or broken propeller
shaft coupling bolts are an indication of misalignment. Misalignment
can also cause severe damage to the shaft log, strut, shaft and the engine
transmission. Realignment should only be performed by a qualified
service person.
The correct procedure for checking the shaft alignment so a boat owner can determine if service work is
required, is as follows:
THE BOAT SHOULD ALWAYS BE AT REST IN THE WATER FOR A MINIMUM OF 24 HOURS
BEFORE CHECKING OR ALIGNING THE PROPELLER SHAFT.
Step 1: Remove the bolts that secure the propeller shaft flanges.
Step 2: Hold the propeller shaft flange firmly against the transmission flange.
Step 3: Try to insert a .004" feeler gauge at the top, the bottom and at both sides between the flanges. If
it can be easily inserted between the flanges in any area, try inserting a larger feeler gauge until
you determine the amount of variance.
Step 4: While holding the transmission flange, turn the prop shaft 90 degrees and repeat step 3. A straight
shaft in proper alignment will not allow the insertion of a feeler gauge larger than .004", regardless
of the prop shaft position.
Step 5: If a gap larger than .004" is found and the gap moves as the shaft flange is rotated, the
flange or the prop shaft is bent out of tolerance and must be replaced or removed and straightened.
If the gap remains at the same position regardless of the propeller shaft rotated position, the engine
must be realigned. At this point, a Pursuit dealer should be contacted.
MAKE SURE THE PROPELLER SHAFT FLANGE BOLTS ARE TIGHTENED SECURELY AF-
TER CHECKING THE ENGINE ALIGNMENT AND BEFORE OPERATING THE BOAT.
LIFTING THE BOAT WITH LIFTING STRAPS OVER THE PROP SHAFTS WILL CAUSE THE
SHAFTS TO BECOME BENT. ALWAYS POSITION LIFTING STRAPS SO THEY ARE CLEAR OF
THE RUNNING GEAR.
