Frequently Asked Questions
Q: How do I know if my helm pump seals are bad?
A: Symptoms include: hydraulic fluid leaking from behind the steering wheel, steering wheel feels loose or has excessive play, difficulty turning, or low fluid level in the helm pump reservoir.
Q: Does this kit include the shaft bearing?
A: This is a seal rebuild kit — it includes the shaft seal, O-rings, and gaskets but does not include the shaft bearing. Replace the bearing separately if needed.
Q: Will this fit my boat?
A: Fits all Seastar HH5271 and Baystar HH5261 helm pumps. Check your helm pump model number stamped on the unit body.
Q: What fluid should I use after rebuild?
A: Use Seastar HA5430 hydraulic steering fluid or equivalent marine-grade hydraulic fluid. Do NOT use ATF or power steering fluid.
Q: Do I need to bleed the system after?
A: Yes. Any time the hydraulic system is opened, you must bleed air from the system following Seastar's bleeding procedure.
