| Part 2: Bleeding a hydraulic steering system, and more
I suspect there is air in my hydraulic power-steering system. What is the procedure for bleeding it? T.D., via e-mail
Next, with the engine turned off, turn the wheel from lock to lock and recheck the fluid level. If there is air in the system, the fluid will be foamy. Continue turning the wheel until the bubbles disperse; this may take some time if you have a lot of air in the system.
After purging all the air from the system, start your engine and let it run at 1000 rpm. Turn the wheel from lock to lock and then back all the way to port. Shut down and recheck the fluid level. It should read between “add” and “hot” on the dipstick. Take the boat for a ride, and while doing some turning maneuvers, have someone listen for any pump noise. If there is any, inspect all lines and connections for leaks. If you still have air problems, you may have a faulty pump.
What causes bottom paint to flake off in certain spots on a fiberglass boat? R.P., via e-mail
The only way to fix this is to remove the bottom paint in the affected area, sand and clean the fiberglass surface, and apply new antifouling.
