Product Details

New SeaStar Solutions HK4300A-3 BayStar hydraulic outboard steering system (no hose). This is the same as the HK4200A-3 kit but does not include any hoses/tubing. Perfect if you plan to purchase a separate SeaStar hose kit, or already have hoses. (For the HK4200A-3 BayStar kit that includes 20ft of tubing, please see here.)

  • 5 Turns Lock-to-Lock (1.4 cu. in. displacement helm)
  • Standard 3/4″ Tapered Keyed Steering Shaft (threaded end of steering shaft is 5/8″-18UNF)
  • Patented No FeedBack™ (NFB) Lock Valves
  • Exceeds NMMA and ABYC Standards

Works For
Single-helm, single-outboard boats under 55 mph and 150 hp. If your outboard exceeds 150 hp or is a pontoon boat, you’ll need the SeaStar kit. If your boat exceeds 55 mph, is a fast bass boat, or has dual-cable steering, you’ll need the SeaStar Pro kit. The BayStar requires a 3″ (76mm) cut-out hole in the dash and a minimum 21″ (534mm) splashwell width.

Comes with HC4645-3 compact cylinder to fit 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: HC4647, HC4648, or HC4658. If you need the HO5090 spacer kit, find it here.

The HK4300A-3 BayStar 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.
