Flapping
My new 310 had excessive play (1-2"!!) at the bottom. Huntrer sent me new nylon bushes but they were the same size as the old. They contributed to the cost of getting new nylon bushes made but would not recognise there was a problem. When you pull your rudder check the condition of the Stainless bearers. They should be 316 steel, but mine attracted a magnet, indicating inferior. Pitting was already obvious, but Hunter didn't want to know!Make sure your new bushes are the appropriate grade for underwater use, as other grades swell considerably!!!Good luck with the job - let me know if I can help furtherjs@screenmedia.tv
