The VARIPROP needs to be greased a minimum of once a year. 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.
How do you feather a max propeller?
The best way to feather the propeller is: Power at 2 to 3 knots in forward. Kill the engine while still engaged in forward. When the engine has stopped, if the shaft is still spinning engage the transmission in reverse to stop the freewheeling.
What is the best folding propeller?
Astern performance
Astern performance was the best of the folding props. At a cruising speed of 6 knots, the engine was turning at 2,300rpm, compared to the 2,500rpm of our standard fixed prop and most of the others on test.
How does a feathering propeller work?
Feathering propellers have a mechanism to change the pitch to an angle of approximately 90 degrees. Usually, a propeller is feathered when the engine fails to produce the power needed to turn the propeller. By angling the propeller parallel to the direction of flight, the drag on the aircraft reduces.
How do you remove a Maxprop?
Place a propeller puller or gear puller onto the shaft in front of the central hub. Be sure only to pull from outside the hub as shown below. If the surfaces on the hub are hit or dinged it can effect the performance of the propeller. Use the puller to remove the hub from the shaft.
Are folding propellers worth it?
Test after test has shown that folding props create the least amount of drag when sailing, especially the two-bladed versions. Some early two-blade designs also provided the least amount of thrust—especially when going astern.
How much faster is a folding prop?
High Speed So by installing a folding prop, you will improve your sailing performance and speed by nearly 15%. Your boat will be faster and the voyages will be more enjoyable even in lighter winds.
What is the advantage of a variprop?
VARIPROP allows you to customize that balance for optimum control, maneuverability and safety. Independent fine tuning of forward thrust means that VARIPROP delivers the best possible performance (speed, thrust, fuel economy) in forward without compromising reverse performance – and vice versa
What is a variprop grand performance propeller?
The all new Variprop Grand Performance (GP) propellers are based on the company’s proven technology and provide ever better performance, reliability, efficiency, fuel efficiency and longevity in all conditions. A. Independently adjustable external pitch control.
What kind of shock absorber does variprop use?
B. SoftStop™ shock absorber – Shock Absorbing Multidisc Brake (patented) built into the VARIPROP hub. Benefits: Dramatically reduces shock loads on gearbox and drivetrain, permits shifting at higher speeds without damage, preserves preset pitches by eliminating hard limit stop impacts (the typical “clunks” of all others).
