The next time you haul out
, consider dropping the rudder
part way down the tube and then drilling a small hole near the top of the outer tube and threading it to take a grease plug
. If the tube is too thin to allow the plug
to be fitted, a welder can braze on a small piece of tubing that itself can be threaded for the grease plug. After restoring the rudder shaft to its normal position, a few pumps from a grease gun from time to time will lubricate the tube and shaft nicely. In the event that the top of the tube is below the water-line and the top fitting is, in fact, a packing gland
, rather than inserting the grease fitting in the tube, use a pressure fitting attached to a short length of flex tubing that can be taken higher than the water line and have a grease fitting attached to it. Again, a few good pumps for time to time should remediate the situation nicely.
As a PS, you may have some rust build-up between the tube and the shaft the a good burnishing with emory cloth will relieve.
