KIMBROUGH 24T. 48P. CARBON FIBRE PINION - KM412

Perfect replacement cogs for Raymarine ST4000 Mk2

By: Derek on 12 December 2018

All I had to do was drill the centre hole out an extra mm and grind of the pinion. Perfect fit for the cogs that had damaged teeth. 3 cogs, less than $30 for parts Raymarine do not supply and I would have had to replace the complete gearbox for over $350 otherwise. Found this out on a youtube video.
