## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth the money
*by B***N on May 13, 2025*

The instructions are pretty good, but can be a little confusing because of all the different motor make/models. It did take me a little bit of trial and error when putting it together and taking it apart. But all the parts are pretty good quality. I am very happy with the final product because it’s so much smoother than my original cable steering. I should have done it sooner.Only drawback, is that the steering column does not tilt up or down. Once it’s set in place, it’s set. There’s probably an after market kit you could purchase but that was the only issue I found

### ⭐⭐⭐⭐⭐ This is great very pleased with This.
*by D***S on September 5, 2022*

I was very happy with this hydraulic steering system easy to install works effortlessly

### ⭐⭐⭐⭐ Great system, shipped with wrong helm cap.
*by J***Y on April 24, 2024*

This is a single helm system which requires a vented helm cap/plug. Dometic must be looking to maximize profits as they ship the single helm system with a non-vented cap. Got the vented cap shipped from Amazon for ~$24.You’ll need SeaStar Solutions HP6126 Vented Plug.
