New SeaStar Solutions (Teleflex Marine) HK4300A-3 BayStar hydraulic steering system. The HK4300A-3 is the same as the HK4200A-3 BayStar kit but does not include hoses or tubing. Perfect if you plan to purchase a separate SeaStar hose kit, or already have hoses. The BayStar features 5 turns lock-to-lock, NoFeedBack technology, and a 3/4″ tapered keyed steering shaft (fits most common steering wheels). It exceeds NMMA and ABYC standards, and is the OEM choice of many boat manufacturers. Comes complete with everything needed to install, including installation instructions.

The BayStar requires a 3″ (76mm) cut-out hole in the dash and a minimum 21″ (534mm) splashwell width. It can be used only for single-helm, single-outboard boats less than 55 mph and 150 hp. If your outboard exceeds 150 hp, you’ll need the SeaStar kit. If your boat exceeds 60 mph, is a fast bass boat or high-performance, or has dual-cable steering, you’ll need the SeaStar Pro kit.

Cylinder (Ram) – Comes with HC4645H compact cylinder, which fits most outboards. Use the application guide in the product images to make sure that is what you need prior to ordering. If you need a different cylinder, find the BayStar kit that comes with it here: HC4647H, HC4648H, or HC4658H. If you need the HO5090 spacer kit, find it here.

Hoses (Tubes) – This BayStar listing does not include hoses or tubes, so that you can purchase your choice of SeaStar hose kit from this list. Be sure to use the measuring guide in the product photos to determine the length you need.
