When loading the boat use the crank shaft to pull the boat securely where you need it instead of slamming it into the roller. More importantly how was the fishing on fork?
bass boat trailers are drive on trailers...they are not float on or winch on and you should rarely if ever have to use your winch........back your trailer to the correct depth,usually with about 2 ft of the bunks showing,put the nose of the boat between the bunks and give the engine enough gas to push the nose firmly against the winch stop....if your partner is in the truck,have him slowly ease up the ramp while you hold the nose against the winch stop with engine trimmed up....when the prop clears the water and you feel the boat sit down on the bunks,shut off the engine....
DO NOT DO THIS IF TEMPS ARE BELOW FREEZING OR IF YOU ARE LAUNCHING,DO NOT UNHOOK YOUR BOAT UNTIL TRAILER IS IN THE WATER
