• Inspect and lubricate seacocks. Hoses and hose clamps should be inspected and replaced as necessary.
• Replace deteriorated zincs.
• Inspect prop(s) for dings, pitting and distortion. Make sure cotter pins are secure. Grip the prop and try moving the shaft - if it’s loose, the cutlass bearing may need to be replaced.
• Check to make sure the rudderstock hasn’t been bent.
• Inspect the hull for blisters, distortions and stress cracks.
• Make sure your engine intake sea strainer is free of corrosion and properly secured.
• Check the engine shaft and rudder stuffing boxes for looseness. After the boat is launched, be sure to check these as well as through-hulls for leaks.
• Use a hose to check for deck leaks at ports and hatches. Renew caulk or gaskets as necessary. OUTDRIVES and OUTBOARD ENGINES:
• Inspect rubber outdrive bellows for cracked, dried and/or deteriorated spots (look especially in the folds), and replace if suspect.
• Check power steering and power trim oil levels. Replace worn-out zincs.
• Inspect outer jacket of control cables. Cracks or swelling indicate corrosion and mean that the cable has to be replaced.

• Inspect fuel lines, including fill and vent hoses, for softness, brittleness or cracking. Check all joints for leaks and make sure all lines are well supported with non-combustible clips or straps with smooth edges.
• Inspect fuel tanks, fuel pumps and filters for leaks. Clamps should be snug and free of rust. Clean fuel filters.
• Inspect cooling hoses and fittings for stiffness, rot, leaks and/or cracking. Make sure they fit snugly and are double-clamped.
• Every few years, remove and inspect exhaust manifold for corrosion.
• Clean and tighten electrical connections, especially both ends of battery cables. Wire-brush battery terminals and fill cells with distilled water.
• Inspect bilge blower hose for leaks.

• Inspect fittings for cracks and rust. Inspect wire halyards and running backstays for “fishhooks” and rust.
• Remove tape on turnbuckles and lubricate threads, preferably with Teflon. Replace old tape with fresh tape.
• Recaulk through-deck chain plates as necessary (generally, once a decade).
• TRAILERS:
• Inspect tire treads and sidewalls for cracks or lack of tread and replace as necessary. Check air pressure. Don’t forget the spare!
• Inspect bearings and repack as necessary.
• Test tail and back-up lights. Test winch to make sure it’s working properly.
• Inspect trailer frame for rust. Sand and paint to prevent further deterioration.

• Check expiration dates on flares and fire extinguishers.
• Check stove and remote tanks for loose fittings and leaking hoses.
• Inspect bilge pump and float switch to make sure it’s working properly.
• Inspect dock and anchor lines for chafing.
• Update or replace old charts, waterway guides.
• Check shore power cable connections for burns, which indicates the cable needs to be replaced.
• Make sure your boating license and/or registration is up to date. Don’t forget your trailer tags.
• Review your boat insurance policy and update coverage if needed. Be sure you have fuel spill insurance coverage.
