The Volvo Penta folding hub kit for 3 bladed props is available as a Saildrive option for 110S, 120S, 120S-E, MS25S, 130S and 150S Saildrives or in different sizes for a tapered shaft. First, choose the correct hub kit for your shaft or Saildrive, and secondly choose the correct 3 blade kit for your yachts length, displacement, engine and gearbox ratio. On a shaft, the hub kit uses a standard ISO taper and keyway size, dependant on the shaft diameter. Contact us for the keyway and taper standard measurements for each shaft.
As a guide:
For 25 mm shaft, the key should be 6 mm
For 1" shaft, the key should be 1/4”
For 30 mm shaft, the key should be 8 mm
For 35 mm shaft, the key should be 10 mm
For 40 mm shaft, the key should be 12 mm
For 1 1/4" shaft, the key should be key 5/16”
For 1 1/2" shaft, the key should be key 3/8”
The correct 3 blade propeller is vital to get the most out of your engine and boat. The power range for the 3-blade propeller is 25-60 HP and it is available in 23 sizes with different pitches and a blade area of 36%. We can help to ensure the correct pitch is ordered. There is also a pre-drilled hub version with an 8 mm hole that requires final machining to the required shaft diameter and taper. It is, however, better to replace the shaft with a standard taper version if the existing taper does not match the standard ISO measurements.
The correct propeller is vital to get the most out of your engine and boat. If you need help in sizing your propeller, please call us first. The power range for the 2-blade propeller is 5-40 HP, 3-blade propeller is 25-60 HP and the 4-blade propeller is 55-120 HP.
Typically, to give an example of efficiency, a folding propeller will reduce a Chanel crossing by 4- 5 hours.
