Traditional Fixed Propellers

We supply high quality fixed propellers at competitive rates for both inboard and outboard applications.

We can also re-pitch, repair,  clean, and balance old or lightly damaged bronze propellers.



Varifold is a superb folding propeller featuring a full helical pitch distribution. Varifold propellers are typically the first choice for Oyster, Baltic, Swan and Moody yachts. Varifold propellers are available in two, three and four blade variants suitable for use with up to 1000hp engines

Autoprop is the first choice feathering propeller for sailboats among cruising yachtsmen the world over

Drag reduction when sailing by at least 85%, changes pitch automatically to suit prevailing wind and sea conditions


Variprop is a superb precision German engineered custom made feathering propeller.

Forward and reverse pitches can be changed in just seconds — even underwater.

Variprop will fit into the smaller prop apertures of older traditional “full keel“ yachts 

Ultrasonic Antifouling Systems:


The Sonihull antifouling system works by producing bursts of ultrasonic energy in multiple frequencies, so creating micro jets of tiny  bubbles that continuously clean the hull surface below the waterline.


Fixed or Flexible

We advise and supply exactly the correct coupling for joining the propeller shaft to the gearbox, whether it is a simple or complex requirement. We can provide both fixed and flexible types suitable for both metric and imperial shafts. We also supply a wide range of adaptors and bobbins.

Sigmadrives are designed to fit virtually all boats from yachts to workboats, canal narrow boats to military vessels; in fact pretty much any powered vessel with engines up to 1300hp.


We typically produce shafts in F51 Duplex or 316 Stainless depending upon the application. We ensure that the correct material is selected to provide, low wear and high resistance to corrosion together with high shear and torque loading strength.

Bell Marine produce both standard and non-standard shafts including matching special tapers, keyways and threads.

We ensure that run-out is within strict tolerances and also ensure the safe handling and packaging of all shafts to ensure that perfect alignment is maintained.
