Yanmar Genuine Alternator Drive Belts
Genuine Yanmar drive belts and water pump belts from FYB Marine. We stock a complete range of Yanmar drive belts and water pump belts, available by mail order or over the counter. FYB Marine is an authorised Yanmar dealer, based in Cornwall.
We supply all genuine Yanmar belts for diesel engines including the 1GM, 2GM, 3GM, 3Y30AE, 4JH, and 6LP range of Yanmar marine diesel engines.
A spare Yanmar belt should be carried on board should the alternator belt or water pump fail whilst out at sea. Ideally, spare impellers and their corresponding O-rings and pre-filters should be carried as spares on board.
