HA6523 Overview
The SeaStar HA6523 restores the original tilt action, wheel support, and locking function with a complete preassembled mechanism rather than a basic repair kit. This kit is ideal when the helm tilt feels loose, will not lock firmly into position, or has worn internal parts that make the wheel feel unstable.

Open LookupFrequently Asked Questions
Does HA6523 replace the entire tilt assembly?
Yes. HA6523 is a complete factory tilt mechanism replacement, not just a few internal service parts. It is meant to replace the full Classic Tilt or Traditional Tilt mechanism assembly.
Do I reuse any of the old tilt mechanism parts?
No. The installation instructions say to use all of the mounting hardware, plates, and mechanism included with the kit and not to reuse the older tilt parts from the old mechanism.
Can I use HA6523 on Sport Tilt or Sport Plus Tilt helms?
No. HA6523 is for Classic Tilt and Traditional Tilt applications. SeaStar Sport Tilt and Sport Plus Tilt helms use different replacement tilt mechanisms.
What problem does this kit usually solve?
It is commonly used when the helm tilt becomes loose, the detents do not hold position well, or the original tilt assembly is worn and needs to be replaced as a complete unit.
Do I need to remove the helm pump from the dash?
The installation instructions show that the old tilt mechanism is removed first and the square mounting plate and helm pump are then reattached using the included hardware. Take care to avoid kinking steering lines during replacement.
