Re: ...looking for information on gas trolling motors...
Saskatoon,
Take your time in deciding what to do. There's more to consider if your going to use a secondary or trolling motor for fishing. Even if you have a just right and great motor, it's important to have the right setup.
Many fishermen setup their boats for these motors and they end up not really using them or not using them to their potential. It's because of the style of the boat, including if the boat is a remote or tiller steer, or the room on the transom, your seating, or the position your in when using it. It could be just one or all that isn't right. The motor then ends up as inconvenient or a hassle to use, or it's awkward to use, or difficult to operate. They then go back to the primary outboard for trolling, as it's just best for them or they compromise, using the trolling motor just once in awhile.
I've been there. I now use a utility boat and it's the best for me with a trolling motor. It's very versatile. Many other boats also work well, some better than others. A boat has to track well to be a good performer, if it doesn't you can compensate by back trolling.
It also makes a difference where and how the motor is used, as on lakes or rivers. A secondary or trolling motor on a river should be highly maneuverable, with fast ease of use. Sometimes you may have to keep one hand on the motor at all times when using it, because of the current and current breaks, eddies, water obstructions, wind, etc. You are also on the motor more for boat control, the smaller and lighter the boat is.
When the setup is right you want to use your motor and it's a great tool.
