I've read many, many posts on this topic and looking for some final advice. My new boat has been ordered but I can still make a change if necessary. We have ordered a 2019 SF21 with SPS and 150hp Yamaha 4 stroke. The SPS package comes with Sea Star hydraulic steering. However, it does not come with power hydraulic assist steering which is a $3100 additional cost - very pricey. The boat will primarily be used for cruising and fishing. We will do some tubing and water sports but that will not be the primary focus. I'm inclined to keep the build as is and see how it goes with the hydraulic steering. However, I could probably convince myself to add it if I dwell on it long enough. At $3100 it seems like I really need to consider it carefully because it ain't cheap. I'm coming form a 24SLi with a 115hp with cable steering.
