I ran a 14ft Lund V-hull with a 15hp Johnson out Turpin for many years, but gave it up two years ago and finally invested in a john boat and a mud motor. In the 90s I could run almost anywhere, but I noticed in recent years the channel is not as deep as it once was. My 15hp had a pin in the transom plate that could be placed in different holes to trim the motor. Johnson and Evinrudes are the same, so hopefully your 6hp model is designed similar. I used that to trim the motor up slightly to run shallower. The trick is getting it just right so that you keep the prop up a little, but not so high that you shoot water everywhere or push your transom shallower. The more you trim up the slower you have to go. I was able to get my boat to plane and once on plane I could run pretty easily in most places along the dike. My guess is that you'll drag a bit more with a 6hp, depending on your load. Good luck!
