In Canada, your boat registration expires after 10 years. Inspect and reinstall all the equipment you keep on the boat: life jackets, fire extinguishers, first aid kit, emergency flares, etc. Make sure the batteries in your flashlight are working. Put all the electronic equipment back in place. Install the battery and check that it holds its charge. Check that all electrical connections are clean and well tightened. If you find any rust, replace the parts. Remove the battery post collar and clean the posts with a metal brush. Check the belts and replace any that are worn. Inspect the protective sheath on the wiring. Don't forget your trailer! Is your registration up-to-date? Do you always have it with you? Are the rollers and bow guards in good condition? Are the wheel bearings in good shape? Is the winch clean and lubricated? Are the tail lights working properly? Are the tires at the right pressure? Are the safety chains still safe? Does your trailer need a touch of antirust paint? If your trailer is made of galvanized steel, you can forget that last step! Once your boat's in the water, you'll be fine and fancy free. Have a great season! *The following lists contain the main things to check when doing annual maintenance on your boat. Before storing your boat or preparing it for the season, you should check the manual you received when you bought it and read the manufacturer’s recommendations.
