Old Town makes a sidesaddle motor mount. They are a little cheaper from Cabela's. I would not clamp to wood blocks. I had a Mohawk Solo 14 and tryed the sidesaddle mount once and it worked ok. The motor needs to be as close to the stern as possible and still be within your reach. You will turn quick to the motors side but turn will be slow to the off side. I disabled the motors bracket lock so when needed you could tilt the motor by pushing down on the motor handle to avoid a log or shallows.
Hope this helps some.
Keep the open side up :~)
