The Tracker "Grizzly" 1448 Jon boats are a good buy @ about $2800 for the hull.

All welded 0.0100" aluminum, no wood, a front deck, flat floor and rear bench seat.


I would get a new or fairly new 4 stroke 20 to 25 hp tiller outboard motor. $1000 to $3500?


A good galvanized trailer with larger wheels would be nice too. $1200


You could put a Minn Kota bow mounted 12 volt electric motor on it with a group 24 deep cycle battery.


I would have oar locks and a set of 8 foot oars or longer? Many use oars that are too short on small boats.


I have had 3 of these over my lifetime of boat ownership.

Many companies make a heavy duty all welded Jon boat series like Lowe, G3, Crestlines, etc.
