Marine Propeller Problems?

If you are experiencing any of the problems listed below! Click on your problem to locate the nearest Prop Scan repair facility to get it resolved.

  • Propeller Induced Vibration
    Propeller induced vibration can be caused by inaccuracies in pitch, camber and section shape. Prop Scan allows us to see and remove these inaccuracies. This results in a smoother, more efficient and often faster propeller. Bring in your propellers for a free examination, we will need information from your vessel performance form.
  • Tip Erosion
    Abrasives present in the surroundings often cause tip erosion. Tip erosion reduces the overall diameter and performance of your propeller. Come and visit us, bring your propeller and your vessels performance form with you and we will show you how we will restore your propeller to better than new.
  • Propeller Cavitation
    Propeller cavitation causes vibration, noise and serious damage to your propeller. Can it be avoided? Cavitation problems must be split into two categories. 1 Propeller induced cavitation. 2 Vessel induced cavitation i.e. cavitation caused by appendages, hull shape and application.
    If the cavitation is propeller induced then we can measure your propeller using the Prop Scan inspection system and show you the cause of it. What do we need? We need your propeller and your vessel performance form to complete your free propeller assessment.
  • Singing Propeller
    Some propellers produce a high pitched noise at certain points between idle speed and full RPM. At the best of times this can be annoying, if this point lies spot in the middle of your cruising RPM it will be intolerable. Help is at hand.
    We will need your propeller and your vessel performance form, with this information we will be able to remove the noise from your propeller.
  • Propeller induced engine overload
    If you are the proud owner of a beautiful yacht but you are a little embarrassed about the black smoke that is emerging from its transom, then it's time to do something about it. Overloading your engine will vastly reduce the overall life of this engine and the black smoke can seriously affect your boating pleasure.
    You don’t have to put up with it anymore. Bring in your propellers along with your vessel performance form and we will tell you, with no obligation to you, what needs to be done to overcome your problem.
  • Propeller not loading the engine
    When an engine revs higher than its recommended maximum RPM, it does not develop its maximum Horsepower. In other words you are not using your engine at its utmost capabilities. Most of the time this means there is additional speed to be gained. How much can we gain? Let us provide you with a free assessment. We will need your propeller and your vessel performance form to complete your inspection.
  • Propellers not synchronized
    Many twin screw vessels have badly synchronized propellers in other words the port and starboard engine are not loaded equally at equal RPM. This is caused by pitch, camber and section shape differences between the two propellers. Can it be resolved? You can bring in your propellers and we will show you what the difference is between the port and the starboard propeller. At the same time we will advise you, at no cost to you, what it takes to resolve your propeller problem. We also require a completed vessel performance form to complete your propeller analysis.
  • Reversing problems
    Reversing qualities are influenced by the position of your propeller and the section shape on the suction side of your propeller. If there is a suction section shape problem, Prop Scan will locate it! Let us scan your propeller, free of charge, and show you how we propose to resolve your problem.
  • Excessive Fuel Consumption
    Does your boat consume more fuel than the recommended amount? The reason for greater fuel consumption is having a low classed propeller. On average, an ISO Class I propeller uses between 5-10% less fuel than a Class III propeller!
  • Poor propeller performance
    Poor propeller performance can be caused by MANY different reasons. Incorrect propeller selection, poor propeller accuracy etc. etc.. What ever it is we will help you find it. Complete the vessel performance form, take your propeller and come and visit the closest Prop Scan shop to you. We will assess your propeller at no charge to you and give you our professional opinion on how his problem can be resolved.
