Would like to extend my cruising range as much as possible.
With trolling motors everything is a compromise.
Adding thrust will let you go a little faster, but you'll drain the battery much sooner.
Quite often the biggest difference in the "salt water " model is the length of the shaft, which won't help you on an inflatable.
On a small boat you'll seldom need the highest speeds or huge amounts of thrust.
It's not hard to drain even a fairly large battery on an all day trip if you spend a lot of time running at the higher speeds or in cold weather.
Keep all that in mind when picking the right model
