Before Upgrade the small aluminum tube was severely corroded and cracked due to poor design and dissimilar metals.
Spacer tube as steel, bolt was stainless and mixed with sea water the aluminum had no chance being the least noble metal. Luckily, I caught the problem before a steering failure resulted.
Improved connecting point incorporates a large aluminum block that allows elimination of the steel spacer tube and provides significant surface area to achieve a solid weld.
Close up of the revised connection point.
