Several times when loading alone, all seems good until just about the time I get up to the bow to attach the winch and it slides back several inches. I've got so I just keep the engine running and in gear until I've got it winched up, then go back to shut off the engine, then back to the front again to get out.
I typically back the trailer in until the top of the back fender is at the water level with maybe 2-3 feet of the bunks out of the water. The only option I know to try is to not to back the trailer in as far, but it already takes a lot of power to drive it up to the bow as is.
Do I need to not back in as far, hammer it down to the limit with the engine trimmed even higher? I have been trimming the engine 3/4 trim.
