Those screws shouldnt have pulled out, they should be through bolted with washers on the inside. Getting stuck in weeds shouldnt rip out your pintles/gudeons. Thats bad workmanship in my opinion.
Bill,
the Stealth dont have kick up rudders. This is the safety mechanism preventing a total stern "rip-off". One of the tradeoffs in the design from putting T-foils on the boat. Wayne pointed this out earlier in the thread.
