As the weather begins to warm up in Central New York, many boat owners are getting ready for their first day on the water. But after months in winter storage, your boat needs more than just fuel and optimism.
At Brinson Marine in Syracuse, this is the exact spring startup process we use in our shop to prepare boats for a smooth, trouble-free summer.
Below is the same checklist our service team follows.
Step 1: Test and Reconnect the Battery
If your boat was properly winterized, the battery should have been disconnected.
Before reconnecting:
• Load test the battery• Charge if needed• Replace if it fails testing• Inspect terminals for corrosion• Tighten connections securely
Loose battery terminals are one of the most common causes of spring no-start issues. Hand tight is not tight enough.
Step 2: Inspect the Engine
Remove the engine cowl and perform a visual inspection.
Check:
• Engine oil level• Wiring connections• Fuel lines• Overall condition
Next, remove the propeller and check the lower unit.
Make sure:
• Gear lube is present• Drain plugs are tight• No water contamination is visible
Catching an issue here can prevent major repairs later in the season.
Step 3: Check Helm and Electrical Systems
Before starting the engine, confirm that all electronics are functioning properly.
Test:
• Horn• Livewell pump• Navigation lights• Docking lights• Mood lights• Gauges• Trim function
Verifying these systems before launch prevents surprises at the dock.
Step 4: Start the Engine Properly
Never run your outboard without water.
Connect a hose to the motor and ensure proper water supply before starting. Once running:
• Confirm water is pumping from the telltale• Let the engine idle for 5 to 10 minutes• Listen for smooth operation• Test shifting into forward and reverse• Turn steering fully left and right
If water is not flowing from the telltale, shut the engine off immediately.
Step 5: Inspect the Trailer
Your trailer is just as important as your engine.
Check:
• Running lights• Turn signals• Brake lights• Winch strap condition• Bunks and carpet• Wheel bearings• Tire tread and cracks• Inflate tires to the manufacturer’s listed PSI
Trailer issues can ruin launch day quickly. A few minutes of inspection goes a long way.
Step 6: Verify Required Safety Equipment
New York State waters require specific safety equipment.
Confirm you have:
• Properly sized life jackets• Fire extinguisher• Anchor and dock lines• Current distress flares that are not expired
Expired flares are one of the most common oversights we see each spring.
Frequently Asked Questions
Can I start my outboard without water?
No. Running an outboard without water can damage the impeller and cooling system. Always connect a hose before starting the engine out of the water.
How long should I run my engine during spring startup?
Let it idle for 5 to 10 minutes while checking for smooth operation, proper water flow, and correct shifting.
What PSI should boat trailer tires be?
Always inflate trailer tires to the PSI listed on the tire sidewall. Do not guess. Proper pressure improves safety and towing performance.

Boats must carry properly sized life jackets, a fire extinguisher, distress signaling devices, and other required safety equipment depending on vessel size.
