Troubleshooting & FAQ
Will this bracket fit a short shaft (S) model?
No, this specific part (6AH-43311-10-8D equivalent) is designed exclusively for long shaft ("L") models of the compatible Yamaha and Parsun outboards. Using it on a short shaft model will result in incorrect engine height and performance issues.
What are the signs my rotary bracket is failing?
Common signs of failure include excessive play or looseness in the steering mechanism, visible cracks or corrosion on the bracket itself, and grinding noises when turning the engine. Seizure or difficulty in steering is a critical sign that the bracket needs immediate inspection and likely replacement.
