Prop Scan

About Prop Scan

Precision Prop Tech has been utilising Prop Scan technology since late 1996 to optimize marine propeller performance, reduce fuel consumption, increase top speed and cruising speed, eliminate propeller vibration and match engine loading requirements.

Using Prop Scan technology, we will measure your propellers, check the accuracy against the ISO 484 International Standards and determine the section form of your propeller.

We can then correct any accuracy problems, apply the correct section form and also tune the pitch of your propellers. An accurate ‘Prop Scan’ propeller with the correct section form and pitch will always out-perform a standard propeller. You will get fuel savings, increased boat speed, reduced vibration, correct engine RPM and correct engine loading.

Utilising Prop Scan we will:

Reduce the level of propeller cavitation which result in improved efficiency and extended propeller life. Cavitation is caused by water vaporizing due to pressure reduction on the propeller blades. This can be caused by mechanical damage such as bent or impacted blades, wrongly matched power to propeller type or incorrect propeller design. This distortion of the flow pattern can significantly reduce power and efficiency and cause erosion of the rotating propeller blades.

Reduce the amount of propeller vibration. Inaccuracies in marine propellers, such as variations in pitch and camber, cause your propeller to vibrate. With the use of Prop Scan these inaccuracies are removed. Prop Scan detects even the most minor variations (it measures down to 0.004″). Using Prop Scan technology, propeller induced vibrations are eliminated, making your vessel smooth, quiet and economical.

Optimize propeller efficiency. Vessels with Prop Scan optimized propellers consume less fuel, saving money and increasing a vessels range. On average, a vessel with a ISO Class S propeller uses between 10 – 15% less fuel than a Class III propeller.

Improve top speeds by precisely optimizing propellers using Prop Scan. After the Prop Scan propeller optimization process, many customers have found their top speed has increased by 2 – 3 knots. Some customers have even experienced increases of 5 – 6 knots!
