Page 4: Operation
For large yachts, equipped with a propeller from our VARIPROP XLS range, we highly recommend to fit a shaft lock to ensure the propeller feathers and stays in sailing position. - Page 5 PITCH ADJUSTMENT „LH“ GERNAL: The pitch adjustment is very simple on the VARIPROP, and can be done in or out of the water in a matter of few minutes. It is not necessary to pull the propeller from the shaft.
- Page 6 PITCH ADJUSTMENT „RH“ GERNAL: The pitch adjustment is very simple on the VARIPROP, and can be done in or out of the water in a matter of few minutes. It is not necessary to pull the propeller from the shaft.
- Page 7 Defining and checking pitch adjustments It is quite possible to set the pitch continuously variable and independently for forward and reverse. The turning of the adjusting screws (2) & (4) at pages 5 & 6 by quarter a revolution ( 90° ) changes the pitch approx.

- Page 9 SERVICING The VARIPROP needs to be greased up a minimum of every 2 – 3 years, depending on the engine hours run, or whenever the boat is hauled. The VARIPROP body should always be completely filled with a high viscosity grease of a hydrophobic nature. Remove the cap screw (5) and screw in the lubricating nipple which is supplied with the tools.
