Hi Guys.. Anyone out there having problems with the twin rudders on a 260 or 25.7 (same boat) mine hum,vibrate and bang depending on speed and point of sail.. They also feel VERY wishy washy .. I have spoken to two other owners who have both had the same problem. But no solution yet ....HELP.... I have even considered fitting a first class 8 or ETAP 23 single rudder .. solution or thoughts PLEASE
