❄️ Why Winterize a Suzuki Outboard Motor?

When winter rolls around, cold weather, humidity, and fuel degradation will ruin an un-winterized boat engine. Not winterizing, your outboard will languish:

• Internal rusting and corrosion
• Damage to engine component or block
• Carburetor or injector gunking
• Damage to the fuel system
• Battery failure
• Costly repair or total replacement of the spring

Suzuki outboards, and the 4-stroke DF series in particular, are highly advanced engines. Winterizing preserves the life, reliability, and performance you’ve placed in it—if your outboard is 2 or 10 years young.

🚤 What Suzuki Outboards Need Winterizing

Almost all Suzuki outboards need to be winterized before long-term storage, including:

• Suzuki DF2.5 to DF350 4-stroke models
• EFI (Electronic Fuel Injection) and carbureted models
• Portable and high-horsepower models
• Short shaft and long shaft models

If the engine will be idle for more than 30 days, winterizing is required.

🛠️ Step-by-Step: Suzuki Outboard Engine Winterizing

🔧 Tools & Supplies Needed:

• Fuel stabilizer (marine-grade)
• Engine fogging oil (for carbureted models only)
• Gearcase lubricant
• Marine engine flush kit or muffs
• Freshwater hose
• Grease gun
• Battery charger or maintainer
• Engine oil & oil filter (replacement if)
• Spark plug socket (replacement if)
• Storage stand or trailer for boat

---

✅ Step 1: Flush Cooling System

Salt, sand, and lake gunk will clog up your cooling passages on your engine. Flushing loosens up those unwanted deposits.

Flushing Your Suzuki Outboard:

• Hook engine flush muffs onto water intakes.
• Place garden hose in and turn water on.
• 10–15 minutes idling start engine.
• Pull engine prior to turning off water.
• Drain engine completely of all water.

---

✅ Step 2: Add Fuel Stabilizer & Run the Engine

Gasoline spoils in 30 days, gumming up injectors and carbs.

Steps:

• Fill gas tank to full with fresh fuel.
• Add specified amount of fuel stabilizer.
• Drive vehicle 10–15 minutes to bleed stabilized gasoline through system.

---

✅ Step 3: Fog the Engine (Carbureted Models)

Fogging removes corrosion in and deposits thin oil protective coating on surfaces inside.

Instructions:

• Remove engine cover.
• Idling engine, fog into air intake with fogging oil.
• Repeat until engine freezes.
• Remove spark plugs and fog directly into each cylinder with fogging oil.
• Hand spin flywheel a few revolutions to spread the oil.

Note: Fuel-injected EFI Suzuki engines can be omitted if a fuel stabilizer is added. Check your manual.

---

✅ Step 4: Change Engine Oil & Filter

Dirty old oil contains dirt in it that will destroy the engine if not drained out.

Steps:

• Preheat engine (5 minutes) to drain.
• Drain plug and filter.
• Drain into pan.
• New filter and add prescribed type of oil (see below specifications).
• Check for leaks, check oil level.

---

✅ Step 5: Drain and Change Gearcase Oil

Water in lower unit will freeze and destroy housing.

Steps:

• Drain pan underneath gearcase.
• Loosen and remove bottom and top drain screws.
• Drain all fluid out.
• Fill bottom drain hole with marine gear oil until it spills out the top hole.
• Replace screws with new gaskets.

---

✅ Step 6: Grease All Fittings

Lubricate to avoid rust and smooth movement:

• Steering parts
• Tilt and trim pivots
• Propeller shaft (pull prop and put on marine grease)

---

✅ Step 7: Disconnect & Store the Battery

• Remove the negative terminal first.
• Store battery in cool, dry location.
• Use trickle charger or battery maintainer during winter.

---

✅ Step 8: Store Your Outboard Properly

• Store on stand or on boat with tilt-down
• Cover with breathable engine cover
• Store in dry, closed area if possible
