The shafts are back today, the props returned yesterday looking like a new pair - Ron has done a beautiful job (again). pics to follow
Feeling the inside bottom edge of the shaft log, Dr Doug could sense that a worn spot had developed where the copper had been in contact with the shaft, being pressed down by the poor alignment.
As is the way these days, alignment seems to be an option not offered by most mechanics? This is the most important aspect of a good smooth running vessel! The meeting of power and water. If the shaft is pressing against the hull, or strut bearings the boat is working against itself, sending power into the hull causing vibration and deterioration of the shaft, bearings and log. The 1 1/4" shaft is easily bent to force a poor alignment - any monkey can do it.
The second picture shows clearly how far down and over to the right the shaft was misaligned.
We searched for a replacement in Washington with two of the specialist parts companies, to find that they are custom made and they require a week to construct replacements.
Since we have been up on the hardstand long enough at this point Dr Doug has decided to save time and money by sleeving the copper tube with a length of fiberglass tubing, epoxied in place. He has been sanding down a lenghth of two inch tube to slip inside the 2 1/8" copper tube, allowing enough room for the shaft to turn freely.
