Side-Power Centa One-Piece Flexible Coupler

Side-Power Centa One-Piece Flexible Coupler Complete

The Side-Power Centa flexible coupler is a complete one-piece replacement component for compatible Side-Power bow and stern thruster assemblies. Three coupler variants are available, each defined by its part number, motor-shaft diameter, drive-shaft diameter, and compatible thruster models.

Because the available versions use different shaft interfaces, both shaft dimensions and the existing thruster model should be confirmed before selecting a replacement. This is a complete flexible coupler spare part rather than a motor, drive leg, or complete thruster unit.

Available Variations

SM201450TC – 28 mm to 20 mm

The SM201450TC configuration uses a 28 mm motor-shaft connection and 20 mm drive-shaft connection. It is listed for the SP200, SE210, and SEP210 thruster models.

YachtAid Marine also carries the Side-Power SE210/250TC 24V thruster and the Side-Power SEP210/250TC 24V proportional thruster for these related model families.

SM201450 – 28 mm to 22 mm

The SM201450 version uses a 28 mm motor-shaft connection and 22 mm drive-shaft connection. It is listed for SP220, SP240, SP285, SE240, SEP240, SE250, SEP250, and SE300 thruster models.

Confirm the exact installed model before selecting this version, as the shared shaft dimensions do not make the coupler interchangeable with the SM201450TC or SM201450HYD configurations.

SM201450HYD – 15 mm to 22 mm

The SM201450HYD configuration uses a 15 mm motor-shaft connection and 22 mm drive-shaft connection and is listed for SP300HYD and SH320 applications.

This hydraulic-model configuration should be selected only when the existing thruster and shaft dimensions correspond to the SM201450HYD specification.

For related service components, see the Side-Power rubber torsion sleeve, the Side-Power thruster drive pin, or browse the bow and stern thruster spare parts category.

Before ordering, confirm the Side-Power model, coupler part number, motor-shaft diameter, and drive-shaft diameter to select the correct SM201450TC, SM201450, or SM201450HYD flexible coupler.
