The conventional shaft Stripper is designed to cater for a wide range of shaft sizes and propeller configurations allowing a perfect match with your boat.
The Stripper is made up of several parts that are assembled in halves and bolted onto the propeller shaft, avoiding having to remove the propeller for initial installation or any future maintenance. The Stripper comes with full colour installation instructions and can be installed by the boat owner in under an hour, avoiding costly boat yard labour fees.
The Stripper package consists of a rotary cutter that clamps onto the propeller shaft and has the same number of blades as your propeller. The rotary cutter also acts as the main structure of the Stripper with the fixed cutter, bearings and clamp ring all mounting onto it.
For a scissor action cutter to work there has to be a stationary blade, the fixed cutter. This is mounted onto the rotary cutter between two delrin bearings and is held in place with a clamp ring. Its stopped from rotating by loosely engaging with a striker plate mounted onto the P bracket, this allows forward and aft movement of the propeller shaft without changing the distance between the fixed and rotary cutter blades.
To select the correct Stripper model for your boat there are a few measurements and facts that need to be known. Use the text and diagram below as well as our interactive Stripper selector to find out which model Stripper will fit your boat.
The shaft diameter governs which model to chose. You can measure the diameter (inside the boat if this is easier) or you may have this information with the specification of the boat. If there are two models that cover your shaft size select the one with a Stripper hub diameter that matches or is bigger than sterngear and propeller boss diameter.
If your shaft size is greater than the sizes supported by our AMxx Strippers, we provide a range of custom built LMxx Strippers. Further details are available on the specialist products page.
Your sterngear will need to have our striker plate secured to it. Our standard striker plate is fastened with machine screws tapped into your metal sterngear. If your boat has a glass reinforced plastic (GRP) stern tube or an oil filled bearing which would make drilling and tapping the striker plate mounting holes impractical, we can supply a special clamp kit instead of the standard striker plate.
Secondly the number of cutting blades on the Stripper should be the same as the number of blades on the propeller. For smaller model Strippers, that only support two or three cutting blades, being installed on boats with four bladed propellers we recommend installing a two bladed Stripper. For a five bladed propeller a three bladed Stripper.
