Perfect Match for Your Raymarine Setup
Designed exclusively for ST50, ST60, and ST80 masthead transducers, this kit revives instruments that have logged thousands of nautical miles. Whether you're racing competitively or cruising coastal waters, maintaining wind data accuracy is non-negotiable. Skip the guesswork—users report crisper readings post-install, helping fine-tune sail trim and plot safer courses.
Quick Installation Guide
- Power down your system and secure the boat in calm conditions.
- Remove the old cups and feather by loosening set screws with the provided wrench.
- Attach new speed cups, ensuring they rotate freely without binding.
- Secure the directional feather and counterweight for balanced operation.
- Tighten everything, remount if needed, and test with a gentle breeze to verify performance.
Pro tip: Inspect bearings during replacement; a drop of marine-grade lubricant can further boost responsiveness.
Maximize Longevity and Performance
Wind instruments endure relentless punishment—bird strikes, ice buildup in colder climes, or debris in tropical squalls. Regular checks catch wear early: erratic speed readings signal cup issues, while wobbling vanes point to feather fatigue. This replacement not only fixes these but equips you for proactive care, like annual freshwater rinses to combat salt crystals.
Real-world sailors note that proactive swaps like this prevent data glitches during critical moments, such as jibing in 25-knot puffs. Pair with protective masthead covers during storage for even longer service intervals.
