Winterizing a boat involves a series of steps that are designed to protect your boat from the harsh winter weather and prevent damage to its various systems. It should usually be done before the cold weather sets in. So, how long does it take to winterize a boat on average?
On average, a small boat with an outboard motor may take between 1 and 2 hours to winterize. A medium-sized boat with an inboard or outboard motor may take between 4 and 6 hours, while a larger boat with an inboard motor and complex systems needs at least 1–3 days.
However, these depend on several factors, such as the size of your boat, the type of engine it has, and the specific winterization procedures recommended by the manufacturer. Let's see how these factors affect the duration of the boat winterization process.
- Jet skis have a shorter winterization process, estimated to be 1–2 hours only, because they have a simpler design and more accessible components.
- Yachts need at least 12–24 hours or more to winterize due to their complex systems and designs.
- Sailboats take 4–6 hours to winterize due to the fact that they have rigging, sails, masts, and keels that need careful attention when winterizing.
- Yachts and cabin cruisers require more time for cleaning and inspection, draining and flushing, fuel and engine care, and protecting the boat's exterior.
- Small boats like jet skis require less time for cleaning and inspection than other boats.
