I have known and used Bell Marine for many years. Paul Bell is the UK South Coast agent for Brunton's and Michigan Wheel propellers, as well as PSS seals and Sonihull Ultrasonic antifouling. He is really knowledgeable and will travel to most UK South Coast locations, but also supplies products to anywhere in the world if required.
He supplied me a few years ago with a Duplex stainless replacement prop shaft as the original had worn badly. It fitted perfectly and still shown no signs of wear at either the cutless bearing or the Volvo seal.
I negotiated a discount of 20% for Jeanneau owners off standard Bruntons products including Autoprops and Sigmadrives as well as on PSS seals and Spurs Rope Cutters. If you mention Jeanneau Owners he will provide extremely competitive prices on all other items including high quality shafts, bearings and fixed propellers.
