The Dometic HH4316-3 1.4 BayStar Sport Plus Tilt Helm is Dometic’s premium BayStar tilt helm for single outboard hydraulic steering systems up to 150 HP (total). It combines the compact 1.4 cu in BayStar helm with the Sport Plus tilt mechanism to give the operator a more comfortable wheel angle on center consoles, dual consoles, and small pilothouse boats.
When matched with a BayStar outboard cylinder such as the HC4645-3, this helm delivers smooth steering, predictable wheel effort, and approximately 5.2 turns lock to lock on typical BayStar installations.

Please verify that HH4316-3 is correct for your boat using the BayStar application guide, hydraulic steering selection guide, and our Tech Support page before ordering.

Installation Tips
- Confirm that your boat and engine combination are within BayStar limits (single outboard, maximum 150 HP total) before installing this helm.
- Use the helm mounting template in the BayStar manual to verify dash cutout and mounting hole locations before drilling.
- Install only genuine SeaStar/BayStar ORB style hose fittings into the HH4316-3 helm ports. Do not attempt to install NPT pipe fittings into the helm.
- Mount the helm so that the fill/vent is at the top position for proper filling and purging.
- Use only Dometic SeaStar/BayStar hydraulic fluid and follow the recommended fill and bleed procedures in the manual.
- After installation, verify full engine movement lock to lock and full tilt range without hose kinking, chafe, or interference.
Maintenance Guidelines
- Check fluid level at the helm regularly and top off with SeaStar/BayStar hydraulic fluid as needed.
- Inspect the helm and cylinder periodically for seepage at the shaft, fittings, and hose connections.
- Rinse external helm, cylinder, and fittings with fresh water after salt water use when possible.
- Service the helm with the HP6032 seal kit if you see signs of shaft seal wear or minor seepage at the helm shaft.
- Follow the routine maintenance schedule and safety checks outlined in the BayStar installation and owner’s manual.
Frequently Asked Questions
Is HH4316-3 the right replacement helm for my BayStar system?
The HH4316-3 is the BayStar 1.4 Sport Plus tilt helm and is typically used in single outboard BayStar systems up to 150 HP (total). To confirm that it is correct for your engine model and cylinder, please review the BayStar application guide and hydraulic steering selection guide and submit your boat and engine details through our Tech Support page.
What is the difference between HH4315-3 and HH4316-3?
Both are 1.4 cu in BayStar tilt helms. HH4315-3 is the Sport tilt helm, while HH4316-3 is the Sport Plus tilt helm that offers a wider tilt range and slightly different tilt geometry for enhanced driver comfort. Displacement and system rating are similar, but the feel and wheel angle options are improved on the Sport Plus version.
Can I use HH4316-3 on a twin outboard boat?
No. BayStar systems (including the HH4316-3 helm) are rated for single outboard engines up to a maximum of 150 HP total. For twin engines or higher horsepower applications, Dometic SeaStar or SeaStar PRO steering is normally required. Use our Tech Support page if you need help selecting a SeaStar or SeaStar PRO system.
Does this helm include a seal kit or tilt mechanism kit?
No. The helm is supplied as a complete tilt helm assembly, but seal kits and tilt mechanism kits are sold separately. The typical helm service kit is HP6032 and the Sport Plus tilt mechanism kit is listed as HA6423 in the Dometic steering selection guide.
Can I reuse my existing hydraulic hoses?
Possibly, but it depends on the hose type and fitting style. The HH4316-3 uses ORB style hose fittings. If your existing BayStar system already uses ORB fittings and the hoses are in good condition and correctly sized, you may reuse them. If you are upgrading from older non-ORB components or from cable steering, you will need new SeaStar/BayStar hoses and fittings.
Why is this part final sale and not returnable?
The HH4316-3 is a specialized hydraulic helm with application limits and safety-critical installation requirements. To keep pricing competitive and avoid restocking safety-critical components, we sell this helm as final sale. Please use the BayStar application resources and our Tech Support page to confirm compatibility before ordering.
Can I upgrade from BayStar with HH4316-3 to a SeaStar or SeaStar PRO system later?
Yes. Many owners start with BayStar and later upgrade to SeaStar or SeaStar PRO when they repower or move to a higher performance hull. The upgrade typically involves a new SeaStar helm, compatible cylinder, and steering hoses. If you plan to upgrade in the future, we can help outline an upgrade path through our Tech Support page.
