PROPELLER SELECTION AND REPLACEMENT GUIDELINES
There are many different propeller designs for specific operating characteristics.
Always consult a certified marine technician when replacing your propeller.
To prevent accidental start-up, complete the following before installing or removing
the propeller:
• Position the shift control in NEUTRAL.
• Position the battery switch to the OFF position and remove the key.
• Place a wood block between the cavitation plate and the propeller to hold
the propeller in place. Remove the propeller nut.
Personal Injury Hazard: Never use your hand to hold
the propeller when removing the propeller nut; the propeller blades are sharp.
Wear protective gloves.
DUAL-PROP DRIVES
Many sterndrive and some outboard-powered boats may use a dual-prop drive.
Dual-prop drives have one prop turning clockwise and the other prop turning
counterclockwise. Dual-prop drives come in rear-facing (sterndrive/outboard) and
forward-facing (pod) designs. With either design the forward prop (referenced to the
bow of the boat) turns counterclockwise while the rear prop turns clockwise.
In dual-prop drives, either prop can have three or four blades and have different
pitches and/or diameters. Some configurations can increase top speed at the
expense of fuel economy. Always treat the propellers on dual-prop drives as a set
and change them out as a set even if only one is damaged. Read the drive
manufacturer’s owner’s information carefully and consult the dealer or a marine
propeller specialist for assistance.
