Works For
Single-helm, single-outboard boats under 55 mph and 150 hp. If your outboard exceeds 150 hp, 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 HC4645H 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: HC4647H, HC4648H, or HC4658H. If you need the HO5090 spacer kit, find it here.

This BayStar listing does not include hoses or tubes. Perfect if you plan to use it with SeaStar hoses, which you can see here. Be sure to use the measuring guide in the product photos to determine the length you need.
