MULTI-E STAINLESS STEEL PROPELLER.NEW SATURN 14X21 LEFT

Function and technical context

The 14×21 Multi-e Inox.new Saturn propeller is the direct propulsion element of the Yamaha engine, responsible for transforming the rotation of the crankshaft into hydrodynamic thrust to move the boat. Made of high-resistance stainless steel, it works in the marine transmission system continuously exposed to salt water, currents and submerged objects. Its left-hand rotation configuration is synchronized with motors specifically designed for this rotation, guaranteeing maximum performance and directional stability; A misalignment or incompatibility in the direction of rotation generates vibrations, loss of power and premature wear of bearings and transmission shafts.

When to replace this part?

Marine propellers should be inspected after each season or every 100-150 hours of operation, looking for cracks, bending, deep corrosion or erosion of the blades that reduces grip in the water. Obvious symptoms of need for replacement include abnormal vibration at low engine speeds, inability to reach maximum declared revolutions, or finding radiating cracks from the roots of the blades. Preventive replacement before the start of the boating season prevents breakdowns in open water and ensures predictable directional behavior and optimal propulsive efficiency.
