We have seven flat bottom river boats from 16 to 19 feet that are perfectly suited to our rivers. We run four stroke Honda outboard motors from 15 to 90 horse power. These motors are very fuel efficient, low emission, and reliable. We chose them because we want to preserve our wilderness and keep it clean. We do not run jet boats up shallow spawning rivers. Instead, we prefer to wade the rivers and fish them unaltered by our passing.
