How To Get Ready: Spring Commissioning Checklist from BoatUS

SPRINGFIELD, Va., March 3, 2020 – Getting the boat ready for the summer boating season is an exciting time for America’s nearly 12 million recreational boaters. Boat Owners Association of The United States (BoatUS) has a Spring Commissioning Checklist to help boaters start the season right, along with a new YouTube Spring Fitting Out video library that shows you how to do some basic tasks, from changing the outdrive oil or fixing broken trailer lights to replacing zincs or changing a propeller.

Before You Launch

1. Inspect and replace hose clamps as necessary. Double clamp fuel lines and exhaust hoses with marine-rated stainless steel hose clamps. While not technically required, it’s a wise move to double clamp whenever possible on all hoses – especially those below the waterline.
2. Inspect all hoses for stiffness, rot, leaks and cracking, and replace any that are faulty. Make sure they fit snugly.
3. Inspect prop(s) for dings, pitting and distortion. Make sure cotter pins are secure.
4. Grip the prop (on inboard drive systems) and try moving the shaft up and down and side to side. If it’s loose and can be wiggled, the cutless bearing may need to be replaced.
5. Check the rudderstock to ensure it hasn’t been bent. Operate the wheel or tiller to ensure the steering works correctly.
6. Inspect the hull for blisters, distortions and stress cracks.
7. Make sure your engine intake sea strainer (if equipped) is not cracked or bent from ice and is free of corrosion, clean and properly secured.
8. With inboards, check the engine shaft and rudder stuffing boxes for correct adjustment. A stuffing box should leak no more than two drops each minute when the prop shaft is turning.
9. Inspect, lubricate and exercise seacocks.
10. Use a garden hose to check for deck leaks at ports and hatches. Renew caulk or gaskets as necessary.
11. Inspect and test the bilge pump and float switch to make sure they’re both working properly.
12. Check stove and remote LPG tanks for loose fittings and leaking hoses.
13. Inspect dock and anchor lines for chafe and wear.
14. If equipped, ensure that the stern drain plug is installed.
15. After the boat is launched, be sure to check all thru-hulls for leaks.

Engines and Fuel Systems

1. 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 noncombustible clips or straps with smooth edges.
2. Inspect fuel tanks, fuel pumps and filters for leaks. Ensure portable tanks and lines are completely drained of stale fuel before filling with fresh fuel. Clean or replace fuel filters and/or fuel-water separators if not done before winterization.
3. Every few years, remove and inspect exhaust manifolds for corrosion (for inboard-powered and inboard/outboard boats).
4. Charge battery.
5. Clean and tighten electrical connections, especially both ends of battery cables. Use a wire brush to clean battery terminals, and top up cells with distilled water (if applicable).
6. Inspect the bilge blower hose for leaks and run the blower to confirm correct operation. Read more:
