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.
Do you leave antifreeze in boat engine?
Do you have to use antifreeze when you winterize your boat? You should use antifreeze to winterize your boat if you have an inboard engine or any systems with pipes or that carry water. You should also consider using it in your bilge. For outboard motors, you don’t have to use antifreeze.
Where do you put antifreeze in boat for winter?

How much antifreeze is needed to winterize a boat?
If you’re going to winterize a boat you’ll need around a five gallon bucket and two gallons of antifreeze to protect your engine and all related plumbing.
What is the difference between marine antifreeze and automotive antifreeze?
Marine antifreeze is non-toxic and often contains rust and corrosion inhibitors that protect your engine during the winter. In contrast, auto antifreeze is designed to be used both as antifreeze and coolant for your car engine and can be extremely toxic and environmentally damaging.
What is the problem with using your boat’s engine to drive it onto a trailer?
Using a boat’s engine to drive it onto a trailer to fully load it is not an acceptable practice. Using the boat’s engine to load onto the trailer is dangerous to your equipment and the people around the loading area. It also erodes the material at the end of the ramp which leads to its deterioration.
What kind of antifreeze should I use to winterize my boat?
Propylene glycol antifreeze with a rust inhibitor is approved for use in the raw water cooling system for cold weather storage purposes ONLY. However, if your engine is equipped with a closed cooling system, you should always use a 50/50 mixture of ethylene glycol antifreeze and water in this system.
Why should a boats gas tank never be completely filled?
It’s important to never fill the tank of your boat beyond 90% full. This leaves room for gas to expand and avoids the potential for overflow. Ensure that all air vents and valves to the gas tank are open.
Is winterizing a boat necessary?
Winterizing a boat is an essential process unless you plan to make necessary repairs to your boat come springtime.

This could cause anything from blowing off a hose to completely ruining your engine.
How can I keep my boat warm in the winter?
Electric boat heaters can be used in the cabin to warm the living space or in the engine compartment to keep the engine warm and dry. Just make sure to get the right one for the job, as cabin heaters and engine compartment heaters (also called bilge heaters) have different uses and features.
