I installed the 150HP variant on my old 19 foot Pro Line that I repowered from an old 2-stroke to 4-stroke. This steering system was very straightforward to install, especially with the help of YouTube videos; I did it on my own. The only part I had someone help with was filling and bleeding the fluid. Honestly, I had a harder time getting the old cable steering system out of the boat because of the corrosion. I've taken the boat out twice so far and it's working as expected. No leaks and steering feels tight and direct.
