I've never had a 208 but have had a similar 22' WA OB in which i had a kicker.
I recommend T9.9 Yamaha or T8 with 25" leg, either will push the boat to a max of 5-6 mph. Be sure to get the electric start and power tilt options.
If you go with a HD adjust. bracket such as the Garelick HD model, you will run into the problem of tying in the kicker to main OB. nice to have in windy days. The bracket does not allow a front tie bar to connect the 2 motors, instead you likely need an EZ steer rod set-up (does job OK, but ugly and cumbersome).
An adjust./drop bracket will also eventually wear out or break down (the initial HD Fulton bracket did not make it even one season, and after 2.5 seasons the Garelick shows definite wear.)
I would go to a fixed bracket (have a local shop fab one up and get it powdercoated and bolt it to the transom). If the bracket is mounted so that both engines are the same height at the steering ram, then you can tie them together.
also, if you are using it for auxilary and emergency power, tiller config will be fine.
If you troll or plan to use it frequently you should go remote or similar set up with the main engine tied together with the kicker such as EZ steer (sucks balls and ugly but does the job ok)
You can also consider TR-1 Gold system to control and pilot the kicker.
Many options, sorry for being long winded.
