What do repair costs include?

    • Repairing your propeller includes straightening, correcting the pitch angle, moderate amount of welding to restore the blades as close to original as economically possible, balancing and refinishing to a new undamaged look.
    • Excessive welding will increase repair costs. We will contact you if this applies.
    • Packaging your repaired propeller in a manner that assures it will not be damaged in shipping.
    • All repairs are shipped within 5 business days after we receive it or sooner if requested

    Can my propeller be repaired?

    In most all cases a damaged propeller can be repaired. A propeller that has developed cracks in the critical areas where the blade meets the hub or if the propeller has been attacked by corrosion or electrolysis the propeller is generally not repairable.

    How does one read propeller dimensions?

    Example: 14-1/2 X  19 RH 3 Blade SS Apollo Propeller

    14-1/2 = The propeller diameter. The diameter is always the first set of numbers.
    19 = The pitch of the propeller. The pitch is always the second set of numbers.
    RH - This is the propellers rotation. Either RH clockwise or LH counters clockwise.
    3 Blade=This is the number of blades. It can be 2, 3, 4, or 5
    SS = This represents the propeller material.
    AL = Aluminium
    SS = Stainless Steel.

    How do I send my prop to you for repair?

    To send your propeller, box it and include the following information:

    1. Name
    2. Mailing address
    3. Phone number (Daytime phone number)
    4. What you need done to your propeller
    5. Any special questions, concerns, or problems
    Note : if you wish we can make the arrangements for you regarding the pickup


    Why shouldn’t I run a damaged propeller?

    Continuing to use a damaged propeller can cause damage to the gear case and ultimately the power head of your motor. When a propeller has sustained damage, it will not spin true, thus creating excessive vibrations that will transfer all the way into your motor.

    A damaged propeller will also not perform as well as a new propeller because the damaged parts of the blade can degrade hydrodynamic efficiency.


    What are the important aspects of the dimensions of a propeller?

    The pitch of the prop is the most important dimension. This usually determines the power and speed of the boat. Pitch is measured in inches and refers to the number of inches a prop would move through the water for every revolution. Of course, since water is a very fluid environment, there is always some percent of slippage involved. The diameter of a prop is usually a set dimension depending on the pitch and make. Most line of props will go down slightly in diameter and the pitch goes up. The reasoning behind this is that the lighter boats that can run higher pitch props don't need quite the diameter as do the heavier boats. If a boat is using a 14 inch diameter prop, and a 14 1/4 inch prop is available in another brand, as long as the pitch is the same, the performance will probably not change.


    Glossary of Terms (Technical Data)

    Pitch     - the theoretical distance in inches that a propeller moves forward in one revolution. Think of a screw in wood. If you increase the angle of the threads, it will move further into the wood in one turn.

    Diameter - the diameter in inches of the circle that the blade tips will cut. Or, the distance in inches from a blade tip to the centre of the prop, multiplied by two.

    Propeller Size     - props are named by the diameter inch number, followed by pitch inch number (i.e. 14 x 19 or 14" diameter x 19" pitch).

    Blade - the part of the prop that acts as a paddle.

    Cupped Blade - a blade that has a lip built into its trailing edge. (Most do) The lip generally helps prop hold water. It also adds the equivalent of about 1/2-inch to one-inch of pitch.

    Polished - a prop that has had the steel polished from a dull to a shiny finish.

    Hub - the centre part of the propeller. The hub, as an actual part, is the piece that fits inside the barrel of a prop and what the shaft slides into. If you strike something, the hub breaks free of the barrel and spins so that you don't damage the drive-train. The word hub is also often referred to as the size of the barrel. (i.e. 4.5", 4", 3", 2.75")

    Skew - a blade whose shape sweeps in a curve that follows its rotation is said to have a skew.

    Rake - if a blade sticks straight out of a hub, in other words, is perpendicular to it, that prop has no rake, or zero rake. If the blade leans back more towards the trailing edge of the prop, it is said to have rake. If it leans way back, it is a high rake prop. Rake can be measured in degrees.
