I picked up a new (to me) boat this year and it has what appears to be a fairly new Minn Kota Edge 55lb on it. Well, the 1-4 settings seem to give me the same level of thrust, which is only good for really light wind days. Once I put it on speed 5, it's really too fast. Anyone else have this problem? Is it normal for this model? Maybe I need a bigger motor. I have a 2001 16 1/2 foot aluminum Sylvan Excursion. Thanks
