How do you winterize an outboard motor?

The basics of winterising your outboard Give the motor a good freshwater flush. Change the lower unit oil.

Do I need to winterize my outboard motor?

If you want your engine to start in the spring and last you many years and plan on not using your engine all winter, you do have to winterize an outboard motor. Winterizing the engine helps to prevent damage during disuse, which is the chief cause for engine failure. Failing to winterize may lead to complications.

How do you winterize a boat motor with antifreeze?

Remove the raw water intake hose from the seacock (this is sometimes difficult, as hose clamps and hoses may be mechanically frozen in place) and insert the end into the antifreeze in the bucket. Start the engine and run at idle until antifreeze discharges from the exhaust outlet for 30 seconds or more.

What does boat winterization include?

At its most basic, winterizing means draining any water aboard or replacing it with enough of the right kind of antifreeze to protect against the lowest temperatures your boat might experience. Winterizing most boats takes from an hour to a day.

How do I keep my boat engine from freezing?

A similar snap-on cover or a heavy-mil plastic garbage bag slipped up over the outdrive and tied at the top will prevent the engine compartment heat from dissipating through the exposed metal. When a freeze is forecast, you can also put your boat back in the water, since water provides greater insulation than air.

Do you have to winterize an inboard motor?

If you’ve got an inboard or a sterndrive (inboard/outboard) boat motor, then winterizing is an absolute must-do. This process prevents gunk from building up, keeps condensation out of the fuel tank and just overall keeps your engine healthy.

Should I winterize my boat myself?

For the handy, self-sufficient boat owner, taking care of winterizing yourself is a great way to save money. Ironically, DIY can potentially even save you some time. Winterizing a boat can be done in less than an hour in many cases, less time than you’d spend just driving the vessel to and from the marina or shop.

Do you leave antifreeze in boat engine?

Note: Sam likes to leave the engine block flushed but empty for the winter. However, some marine engine manufacturers recommend filling the entire engine with RV antifreeze. Always follow your engine manufacturer’s advice.

At what temperature should I winterize my boat?

As soon as the weather gets below 32 degrees, water begins to freeze, with water with impurities or saltwater in it starting to freeze at 28 degrees. In most cases, the water will not freeze solid (leading to cracked engine blocks) until the temperatures stay below 32 for several days and nights.

What happens if you don’t winterize your boat?

If You Don’t Winterize Your Boat, Here’s What Happens: Water freezes and expands and can damage anything it’s trapped inside. Water may seep into unprotected spaces to do this. Acidic and corrosive wastes, salt and corrosion buildup can damage delicate parts in engines. Fuels break down or grow dirty.

Do outboard motors freeze?

A very popular question asked by a concerned boat owner, (mainly outboard motorboats) is Will A Boat Motor Freeze? The simple answer is yes. If the temperature is low enough, it can freeze. Water, oil and other engine related lubrication coupled with freezing temperatures is the main culprit for freezing a boat motor.

Do you have to winterize a 4 stroke outboard motor?

Like inboards and sterndrives, outboard engines are also subject to potential damage from freezing and from being laid up in disuse for months at a time. So outboards demand winterizing too. To serve as our example, we used a Yamaha F150 four-cylinder outboard.

How do you winterize a boat motor without starting it?

Two things need to happen: Oil Change and Anti-Freeze the Raw Water side of your motor. Oil Change works best if you can run the motor for 5 minutes or so and let it warm up. Helps make it flow easier and resuspends the particulates for easier drain/suck out.

Can I use RV antifreeze in my boat engine?

RV antifreeze and marine antifreeze are chemically the same. For most parts of winterizing your boat, RV antifreeze can absolutely do the job for a boat.

Is fogging oil necessary?

Fogging a boat engine is not completely necessary but is highly recommended. Putting a stabilizer in your gasoline can help reduce the long-term storage issues but is not a guarantee. Essentially, fogging oil is an inexpensive way to better protect your boat engine while it’s left idle.
