Boat trailer winches usually have a small 'L' shaped lever that locks a cog to engage/disengage the drive. These often rust up and are hard to move.
If your boat trailer is situated properly you will need very little effort to get the boat up onto the trailer. Using the engine will result in possible major damage to the boat, the trailer and its towing vehicle. It's always best to use the winch and crank it up slowly as in that manner you are in full control of things, whereas with the motor you are not.

A tilt trailer is the best type of trailer to have I think, since you don't need a boat ramp to launch your boat. I have a tilt trailer. First, make sure your boat and trailer are balanced properly. The boat weight should be forward of the axle slightly, so that the trailer does not tilt when the bow of the boat is touching the bow stop. Balance the trailer and boat by adjusting the axle and bow stop positions on the frame. (The tongue weight also has to be right, of course.) Also, if your trailer has bunks, the majority of the boat's weight should be on the keel rollers and not the bunks. Finally, all the tilt trailers that I have seen have a safety chain wrapped underneath the trailer tongue to keep the trailer from tilting too much. I think that's a good feature to have. When launching, back up to the water (on the beach or boat ramp) until the water is deep enough. This depends on your boat and prop length. For my boat, I back up until the water level is just below the wheel bearings or axle. Pull the tilt pin. Also, some tilt trailers have a lever that lowers the bunks to reduce friction. Start to slide the boat backwards, holding onto a bow line. If your boat is heavy, you may want to use the winch to control the speed, as the boat can accelerate as the trailer tilts. As the boat moves backwards, the trailer automatically tilts back. The boat just rolls along the keel rollers into the water. When retrieving your boat, the process is just reverse. As you winch the boat up on the aft keel roller, the trailer automatically tilts back. As the bow reaches the bow stop, the trailer frame levels out again. Before you drive off, remember to replace the tilt pin! A tilt trailer is pretty easy to use and you usually don't have to submerge your wheel bearings in the water!

You can get a boat trailer registration from the DMV for your state.
Back the trailer into the water until the last 2" of bunk boards are still out of the water. Get on pontoon boat and drive it toward the bunks board you can still see above the water, slowly. Even though you are going slow, you will still have enough momentum to overcome the drag of the bunk boards that are above the water. These will help hold the boat in place while you go to the front, if you don't have help, and connect the winch hook. If there is a lot of current you may need to leave the boat in forward gear, pushing it against the trailer, until the winch cable/strap is connected to the boat. Slowly pull the boat out of the water, checking as it come out to see if the boat is centered in the bunks. If it is not you may need to back it back into the water enough that the back end floats, so you can center it on the bunks.
This could damage the engine.
To put a pontoon boat in the water, follow these steps: Ensure the boat is properly secured to the trailer. Back the trailer into the water until the boat floats off. Disconnect the boat from the trailer and secure it to a dock or mooring. Remove the trailer from the water.
No problem, it is perfectly OK to drive your boat on to the trailer with the engine as long as there is enough clearance to keep the prop from hitting anything or anyone. I used to do it all the time. As soon as you start to feel resistance from the hull resting on the trailer skids stop and use the winch the rest of the way.
Trailer ratings are based on the total weight of the trailer and boat.
