Oh that so cool.... kinda reminds me Bruce Mitchel off of the show Swamp people(a wicked show)....
He drove a Vanguard surface drive motor however....
He has a handle mounted to the right side and operate the motor with his left hand. he stands however......
Based on how typically people operate the types of boats like this.... balance wise Id probable stand and operate with a Z bend in the shaft to allow the good relaxed angle.
