3-Blade Shaft Folding propeller

Low drag under sail - maximum thrust under power

 

The 3-blade Flexofold folding propeller provides trouble-free handling and superior power in both forward and reverse.
When folded, the low propeller drag ensures you and your boat will sail faster, and in lighter wind as well - even with a small risk of catching lines or seaweed.
Original propeller for Beneteau, Dehler, Hanse Yachts, Jeanneau, Sunreef Catamarans, X-Yachts and many more!​

Total length of the folded propeller:



 

 

ISO hub length (A), 3-blade up to 23"

 

25 mm shaft, 1:10 taper = 120 mm ≈ 4 47/64"
30 mm shaft, 1:10 taper = 136 mm ≈ 5 23/64"
35 mm shaft, 1:10 taper = 146 mm ≈ 5 3/4"
40 mm shaft, 1:10 taper = 156 mm ≈ 6 9/64"
45 mm shaft, 1:10 taper = 196 mm ≈ 7 23/32"

SAE hub length (A), 3-blade up to 23"

1" shaft, 1:16 taper = 136 mm ≈ 5 23/64"
1 1/8 shaft, 1:16 taper = 146 mm ≈ 5 3/4"
1 1/4" shaft, 1:16 taper = 156 mm ≈ 6 9/64"
1 1/2" shaft, 1:16 taper = 194 mm ≈ 7 41/64"
1 3/8" shaft, 1:16 taper = 177 mm ≈ 7"
1 3/4" shaft, 1:16 taper = 210 mm ≈ 8 9/32"

IMP hub length (A), 3-blade up to 23"

1" shaft, 1:12 taper = 116 mm ≈ 4 37/64"
1 1/4" shaft, 1:12 taper = 136 mm ≈ 5 23/64"
1 1/8 shaft, 1:12 taper = 120 mm ≈ 4 47/64"

Blade length (B), 3-blade propeller:

14" = 151 mm ≈ 6"
15" = 163 mm ≈ 6 27/64"
16" = 176 mm ≈ 6 15/16"
17" = 189 mm ≈ 7 29/64"
18" = 202 mm ≈ 7 61/64"
19" = 216 mm ≈ 8 1/2"
20" = 227 mm ≈ 8 15/16"
22" = 252 mm ≈ 11 7/64"
23" = 266 mm

Please be aware:

  • Unlike the general perception, even as little as 8-10 mm of free space between propeller and hull will be fine. However, this of course depends on the specific hull shape.
  • Due to the nature of the propeller construction, folding blades are positioned further aft than a fixed propeller (see hub length) and thereby leave more space between shaft and hull.
Description

Special features

  • Helical gearing between the blades ensures a syncronized folding mechanism.
  • Protective cover over the gearing
  • Easily replaceable anode
  • Large shock absorbers for quiet opening of the propeller
  • Mounting screws are pre-applied with Loctite for mounting above as well as under water.
  • Water lubricated - no need for maintenance

Sizes available

The 3-blade propellers for shaft installation are available in diameters of 14" to 24" - all in a wide range of pitches.

To be supplied for both LEFT and RIGHT turning shafts.
