It's almost time for summer fun! Working your way through this checklist will help make sure your boat's ready to go when you are.
Getting Started
✓ If necessary, reinstall batteries. Top up lead acid batteries with distilled water. Fully charge batteries. Clean, tighten electrical connections, especially terminals of battery cables. Coat battery terminals with insulating film of grease, or apply protective battery terminal spray. ✓Open and close seacocks; handles should move freely. Hoses should be double-clamped with stainless-steel hose clamps. Replace any that look rusted. ✓ Inspect the raw-water intake strainer to be sure it has not cracked, and is clean and free of corrosion. Make sure the strainer's top fits snugly. ✓ Check running lights. Clean/tighten connections or replace bulbs to assure that all are operating properly. ✓ Check VHF and GPS antenna connections by disconnecting and spraying with moisture-displacing lubricant, then reconnect and test. ✓ Look for indications of leaking at trim cylinders and hoses as well as at hydraulic steering pumps and rams. Replace the O-ring or gasket if leaking. ✓ Make sure the stuffing box or shaft seal is completely dry when the boat is at the dock. ✓ Inspect portlights, hatches, and deck fittings for dirty or displaced caulking, water trails, dirt, and green corrosion, any of which signals a leak that needs to be re-caulked. ✓Test bilge pump and high-water switches and alarms. ✓ Test smoke and carbon monoxide alarms, LPG and gasoline fume detector. ✓ Check flares (expiration date) and fire extinguishers (charge), and replace/ recharge as necessary. ✓ Check and service safety gear such as life jackets, and MOB gear.
Boats Ashore
✓ Inspect props for dinging, 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. ✓ Replace plastic fittings near the waterline with bronze or Marelon. ✓ Inspect the anodes on the shaft, out drive, and trim tabs. Replace any that are close to half-deteriorated. ✓ Check to make sure the rudder stock hasn't been bent. ✓ After the boat is launched, be sure to inspect around the rudder and all thru-hulls for leaks, and check the stuffing box while underway to make sure there is a steady drip.
Out drives and Outboards
✓ Check out drive bellows for cracks and tears (look especially in the folds). ✓ Check hydraulic trim fluid. If you didn't change it last fall, change it now. ✓ Check lower-unit lube level. Creamy oil indicates water (and a bad seal). Many manufacturers recommend changing the oil every year.
Engines and Related Systems
✓ Flexible gasoline lines should say "USCG Approved, J1527." Replace any that don't. ✓ Are fuel hoses supple, with no cracks, bulges, or soft spots? Do the lines smell like gasoline (wipe the lines with a clean rag and then smell the rag)? Did you also use a rag to detect odors at connections? ✓ Cooling hoses should fit snugly and be solidly clamped. ✓ Replace any hose clamps that show signs of corrosion. ✓ Replace fuel filters. ✓ Clean or replace the air filter. ✓ Change engine oil unless done in the fall (preferable). Check fluid levels: transmission, hydraulic steering fluid, and coolant. ✓ Check belts for tension
