WOSP high torque, lightweight, gear reduction starter motors are manufactured in the UK. Unlike alternatives in the market place these are built using only 100% OE parts and units, therefore can't be rivalled on quality.
In most cases WOSP starters are designed with an indexable 360 degree mounting plate meaning no obstruction should get in your way when installing.

The main advantages over the original starter is the durability along with a weight and space saving. The improved performance means they also reduce loads on the vehicle's battery and electrical system.
Direct replacements to the original item, plug & play / fit & forget.
All units come with instillation instructions and a 12 month warranty.

Powerlite offer a wide range of high torque gear reduction starter motors. The lightweight units offer increased cranking speeds and considerably more cranking power than original units, whilst drawing less current from the battery. The units are ideal for road competition applications, especially where engines have been tuned and adverse conditions require extra performance from the starter motor. All Powerlite starters are direct replacement for original units and require no modifications to the vehicle on which they are installed. The compact lightweight units are often easier to install than the original unit and units are modified where necessary to aid fitment.

Starter Motor

Restore fast and reliable engine starting with this OE Match Starter Motor.

The starter motor is an essential part of the vehicle's starting system. When the ignition is activated, it uses electrical power from the battery to turn the engine over until combustion begins and the engine can run independently.

Fits:

• Porsche Boxster 987 MKII 2.9L 2009-12
• Porsche Boxster S 987 MKII 3.4L 2009-12
• Porsche 997 MKII Carrera C2 3.6L 2009-12
• Porsche 997 MKII Carrera C4 3.6L 2009-12
• Porsche 997 MKII Carrera C2S 3.8L 2009-12
• Porsche 997 MKII Carrera C4S 3.8L 2009-12
• Porsche 997 MKII Turbo 2010-13
• Porsche Cayman 2.9L 987C MKII 2009-12
• Porsche Cayman S / R 3.4L 987C MKII 2009-12

A worn starter motor can result in increasingly slow or intermittent cranking and may eventually leave the vehicle unable to start. This OE Match unit provides a replacement solution for a worn, unreliable or failed original starter.

What Does a Starter Motor Do?

The starter motor converts electrical energy from the vehicle's battery into mechanical rotation.

When the vehicle is started, the starter motor engages with the engine's flywheel or drive plate and rotates the crankshaft. This creates the initial engine movement required for the combustion process to begin. Once the engine starts, the starter disengages.

A correctly functioning starter motor provides:

• Strong and consistent engine cranking
• Reliable cold and hot starting
• Correct engagement with the engine
• Efficient use of battery power
• Fast engine start-up

Why Do Starter Motors Fail?

Starter motors are powerful electrical components that experience substantial loads every time the engine is started. Internal components gradually wear, while engine-bay heat and repeated heat cycles can accelerate deterioration.

Common causes of starter motor failure include:

• Worn internal brushes
• Solenoid deterioration
• Worn bearings or bushes
• Wear to the starter drive mechanism
• Electrical connection problems
• Internal electrical faults
• Heat-related deterioration
• Age and high mileage
• Repeated starting cycles

A weak battery or poor electrical connection can produce symptoms similar to a failing starter, so the battery, terminals and main electrical connections should also be checked before replacement.

When Should a Starter Motor Be Replaced?

Replacement should be considered if:

• The engine cranks noticeably slower than normal
• Starting becomes intermittent
• A clicking sound is heard but the engine does not crank
• The starter occasionally fails to engage
• Grinding or unusual noises occur during starting
• Starting becomes particularly difficult when the engine is hot
• The starter motor has been diagnosed with an internal electrical or mechanical fault
• The starter no longer operates

Starter motors do not normally have a fixed replacement interval. They should generally be replaced when testing confirms deterioration or failure.

A healthy starter motor is essential for dependable operation. As these vehicles age, starter motors can develop internal wear that results in slower cranking, intermittent operation or complete starting failure.

Starting problems should be diagnosed carefully because similar symptoms can also result from a weak battery, poor battery terminals, damaged cables or other electrical faults.

Once a starter motor has been identified as the cause, replacing the worn unit restores the mechanical cranking action required to start the engine reliably.

When replacing a Porsche starter motor, it is also worthwhile checking the battery condition, main power cables, earth connections and associated starting-system wiring.
