Common Questions

What sizes are available and how do I choose the right one for my boat steering wheel?
The product comes in three sizes: 11 inch ($109.99), 13.5 inch ($132.99), and 15.5 inch ($157.99). All variants are without a handle. Choose based on your steering wheel diameter; measure your wheel's spoke or rim spacing to ensure a snug fit.
What material is the steering assist ball made of and how should I care for it?
It is made of 304 stainless steel, which is corrosion-resistant and suitable for marine environments. Clean with fresh water and a mild soap after use; avoid abrasive cleaners to maintain the finish.
What is included in the package? Does it come with mounting hardware?
The listing specifies variants as 'without Handle', which indicates the knob itself is included. Exact contents (mounting bolts, adapter, etc.) are not detailed; please check the product description or contact the seller for complete inclusion details.
Is this steering knob suitable for my boat?
This product is designed for fishing boats, yachts, and vessels with hydraulic steering systems. It is not for use on cars, land vehicles, boats with cable steering, or small inflatable boats/dinghies. Also, it is a knob without an integrated handle, so choose accordingly.
What are the shipping times and are there any restrictions?
This item ships from China. Delivery typically takes 7–30 days depending on the shipping tier selected. International orders require human approval at checkout for processing.
