Underwater Gear Propeller Shafts
Check the propeller shaft is running true when the boat is out of the water. A simple visual check for signs of wear, particularly Propeller near the P-bracket where a ‘ring’ Shafts of wear can appear and any bend, which can be caused by hitting the bottom, can help to highlight any bad oscillation.
Rudders Rudder stocks can split at the fork where the blade joins and should be examined. Sometimes the rivets loosen and the blades need to be tightened.
Rudders
If there appears to be more serious damage or electrolysis has set in then a new rudder is usually the only option. Look for signs of ‘pinkness’ and pitting in the blade close to the stock. Look for bent blades, electrolysis around the stock (if metals have been mixed) and snapped rudder stocks.

Check the bolts are holding firm and that there is no sign that the P-bracket has been knocked and bent at all. A more regular maintenance check and replacement of the cutlass bearing is by far the most common problem with P-bracket enquires.

Anodes
If you have a mix of metals underwater then a right anode helps guard against electrolysis. Replace anodes if eroded or damaged. Remember not to antifoul over anodes as this will prevent them working as they should.
