Through years of sailing in salt water, and not trailering my boat I have been frustrated by a worn out keel that wobled and slapped every time a small wave hit.When I finally examined the situation by unscrewing two bolts and busting off two bolts that refused to unscrew.The bolts are part of two seperate U-joints,one on each side of the pin the keel swings on. After years of wear, the keel swinging on the pin, the hole, to accomodate the pin, became so large it wore through the keel. The constant slapping of the keel as a direct result caused a leak and damage to the port side of the housing where the lock pin is also located.The keel is severely deteriorated through years of being submerged in salt water.I long for a permanent keel. Any ideas ? Thank You.
