3100 OFFSHORE

Step 1: Make sure that no burrs

or rough edges exist

on the shaft, key and

keyways. Fit the key

into the keyways. It

must slide freely into

position without hav-

ing side play. It might

be necessary to file the

key with a flat file to

create the correct tol-

erance.

Step 2: Without the key in-

stalled, slip the pro-

peller on the shaft by hand as far as it will go. Mark the location at the front of the hub with a dry-

marker and remove the propeller.

Step 3: Install the key in the shaft.

Step 4: Again, slide the propeller into position by hand. Please note that the key should not extend beyond

the forward edge of the propeller hub. The propeller should reach the same spot as before. If it does

not, the key has probably moved up the keyway, or the key does not fit properly in one or both of

the keyways.

Step 5: Install the propeller nuts. When installing the shaft nuts, take care not to tighten them too much.

Do not force the nut into a tighter position by using a hammer or extension on the arm of the wrench.

Tighten the thick nut, then lock the thin nut tight against the thick nut and insert the cotter pin.

If not properly installed, the propeller will be off balance, and this is a frequent cause of vibration. It could

also cause the propeller hub to split.

DO NOT ATTEMPT TO OPERATE THE BOAT IF THE PROPELLER DOES NOT FIT PROP-

ERLY ON THE SHAFT. PROBLEMS SUCH AS SHAFT VIBRATION, PROPELLER HUB

FAILURE OR SHAFT FAILURE MAY OCCUR.

KEEP AWAY FROM THE PROPULSION MACHINERY DURING ITS OPERATION OR WHEN-

EVER THE BOAT IS IN MOTION. MOVEMENT OF WATER PAST A PROPELLER CAN

CAUSE THE PROPELLER, SHAFT AND OTHER PROPULSION MACHINERY TO ROTATE

EVEN IF THAT EQUIPMENT IS NOT BEING OPERATED INTENTIONALLY.

BEFORE CHANGING PROPELLERS TO CORRECT BOAT PERFORMANCE PROBLEMS, BE

SURE OTHER FACTORS SUCH AS LOAD CONDITIONS, ENGINE TUNING, BOTTOM AND

RUNNING GEAR GROWTH, ETC., ARE NOT THE SOURCE OF PERFORMANCE CHANGES.
