I recently purchased 2024 819 with a mercury 200 (manual jack plate). My previous boat didn't walk, so this is new to me. I am still in the break-in period for the motor, so I haven't had a lot of seat time in it yet. When I do my short periods at full throttle, it walks even though I don't even have it trimmed up halfway. Can anyone give me some tips on how much you usually have it trimmed at full throttle and the best way to control the walk? thanks
