Can I use a true inboard?

You can use a sterndrive in the Great Alaskan, but not a true inboard.  A true inboard has the motor mounted forward in the boat and a prop shaft running through the keel to a propeller.  A sterndrive, and its 'leg' has the motor mounted against the inside face of the transom, and the leg is mounted against the outer face of the transom, the motor and leg together 'clamp' the transom.  This arrangement keeps the weight of the motor very near the transom as designed.  A forward-motor inboard places the motor's center of gravity too far forward (too far for this particular design):

A STERNDRIVE is OK since it puts the weight of the motor and leg on or near the transom - The Great Alaskan IS designed for using a sterndrive (or outboard(s)):

(Example boat is NOT a Great Alaskan - FYI)



A true inboard is NOT OK since it puts the weight of the motor too far forward and that causes the boat's center of gravity to be too far forward (bow-down trim):
