Stripper Parts

The Stripper can be installed on any conventional shaft driven boat or saildrive boat. Both installations consist of a rotary cutter that has two or more blades matched to the number of blades on your propeller and will rotate with the propeller. To form a scissor action there has to be a stationary or fixed cutter blade that the rotary blades pass.

examples of rotary cutters

The rotary cutter forms the main body of the Stripper and can consist of 2, 3 or 4 blades.

With conventional shaft Strippers the rotary cutter is machined to match the propeller shaft size diameter, with the fixed cutter, bearings and clamp ring all mounting onto the body of the rotary cutter.

examples of fixed cutters

The fixed cutter consists of one cutting blade mounted and held in place between two white bearings.

The conventional shaft Stripper fixed cutter is prevented from rotating by the Striker plate (see below), the saildrive Strippers have a locking pin that extends into the saildrive leg.

examples of striker plates

The Striker plate is used to stop the fixed cutter from rotating on a conventional shaft Stripper, it is mounted onto the P-bracket or stern gear via either 3 locking bolts or via a custom built clamp kit.

examples of bearings and clamp ring

All Strippers have bearings, these are white circles of Delrin that go either side of the fixed cutter, they are the only wearing part of the Stripper. Replacement bearings are available in our service packs

The bearings and fixed cutter are held in place on the conventional shaft Stripper by a clamp ring.

examples of modified anodes

Saildrive legs often have several anodes attached to them, the main anode that the manufacturer installs mounts between the back of the saildrive leg and the propeller.

This is where the Stripper is located, we therefore provide modified anodes that are compatible with the Stripper. Sea water anodes are made from Zinc, fresh water anodes are made from Magnesium. Anodes are designed to last approximately one season, but this life can be increased or decreased by many factors, most notably the material and size of the propeller. Large bronze propellers can reduce the life of an anode considerably.
