CHAPTER 7
Propellers
Out-of-balance or nicked props will effect performance or cause
vibration. Damaged props should be replaced, but those that are
chipped or bent can usually be reconditioned by a marine dealer or a
propeller repair facility. When cruising, consider carrying a spare set
of props on board because many marinas do not carry a full inventory
of replacement propellers. Also, carry an extra set of prop hardware.
Refer to the manufacturer’s engine manual for appropriate stern drive
and inboard propeller replacement.
Be sure to make a note of the propeller diameter and pitch while the
vessel is in dry dock. They are pressed into the prop for easy reading.
In an emergency a stainless steel propeller blade may be straightened by
laying the propeller blade on a 2 x 4 and hammering the bent portion
of the blade until straight. This procedure may aid the operator in
reaching port so he can have the propeller re-pitched.
