Operation
- If the steering cable feels stiff when used, the cable is not safe to operate. Replace the cable immediately.

- Do not cover any cracks in the steering cable with tape or other sealants. Doing so might lead to the cable failing suddenly and without warning.
Loss of steering control hazard
The engine can be over-trimmed, causing the steering torque to increase so much that the steering wheel becomes impossible to turn, even if you don’t feel the torque at the wheel. This might make the steering feel locked. This situation can happen when jack plates are used to raise the engine on the transom. The only way to fix this is by either lowering the boat speed or adjusting the engine trim to a less extreme position. Until you fully understand how the boat and power trim work together, be very careful when making trim adjustments.

- Make sure the steering wheel responds right away when turned.
