LAUNCHING A BOAT
Back into the water far enough that the lower unit cooling water intake holes are submerged. (NOTE: use the parking brake on the towing vehicle at this point, and do not allow the tow vehicle's wheels to enter the water unless necessary).
Release the winch line and slowly reverse the boat off the trailer.
Secure the boat to the dock, and then promptly move the tow vehicle and trailer away from the launch to avoid keeping other boaters from waiting.
If you anticipate problems with your boat engine, start the engine and let it warm up while the boat is still attached to the winch line. It is much easier to retrieve the boat when it is still on the trailer.
PREPARE YOUR BOAT AWAY FROM THE RAMP AREA TO AVOID CREATING UNNECESSARY DELAYS AT THE LAUNCH AREA.
