what is the difference between an inboard and stern driven
A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive.he drive unit (outdrive) carries power from the inboard engine, typically mounted above the waterline, outboard through the transom and downward to the propeller below the waterline.
Report Abuse. Some of the inboard boats use a propeller that is on a shaft the extends from the bottom of the boat. Turning is done with a rudder. These are OK if you are never going to run your boat aground or go through shallow water. With an I/O you can raise the prop to more easily go through shallow water.est Answer: A true inboard is quite a bit more maneuverable than an I/O.In my honest opinion the inboard wins hands down in all categories but the shallow water one.The I/O drive can be trimmed up whereas your stuck with what you've got with an inboard.The power to get a skier up is amazing with an inboard.
