It is very important that you look after your boat trailer. If your trailer becomes unusable, you can’t transport your boat so your boat is unusable, too.

Trailers are made to fit a specific model of boat. They are not interchangeable between different boat models. So if your trailer becomes unusable, it will be difficult to find a used trailer that will fit your boat.

You will probably have to buy one new or have one made. This will be very expensive and the new trailer could easily cost much more than your pre-owned, second-hand used speed boat, power boat or motor boat is worth.

To launch your boat, you have to back your trailer into the water. Water is corrosive. If its salt water, its even worse. And if you are launching from a beach, sand is also corrosive. So clean your trailer after use, inspect it regularly and treat any corrosion.

As you tow your boat, the grease around your trailer wheel bearings heats up and becomes liquid. When you back your trailer into the water, some of this liquified grease can leak out as water leaks in. So it is important to re-grease the trailer wheel bearings regularly.
