I have an 18ft Bass Tracker with a 40hp engine.
It doesn't take much to really run it, and it doesn't go FAST, it cruises. BUT, when the lakes are low (Which happens a LOT in Central Texas), we can take our boats farther up the lake. Especially Lake Georgetown, I've caught some nice fish in the shallower parts of the San Gabriel river.
I'd go take a picture, but there really isn't much to show off.
