Re: Is short shaft enough for my Starcraft SS?
The short shaft will work just fine. If it had more hp, then it might cavitate due to the boat moving fast enough to remove water from behind the transom (planing) causing it to starve. I have ran short shaft kickers behind my 18' chieftain from 4.5 hp to 12 hp. My kickers do not ride as low as yours on an adjustable mount and only the 12 hp cavitated at wide open throttle and even then only in short spurts.
I usually run a 7.2 hp. It has the best balance of power, weight, fuel economy and noise. I tried a 6 hp evinrude once, it did ok except in windy conditions. It did not have enough power to overcome the wind resistance and I had to constantly steer to hold a course. It was a 6 hp lake, but I gave up and cheated. I started the main I/O and idled it in gear while my son sat on the floor to hold the steering wheel straight while I sat on the transom and used the kicker to steer with. Nobody noticed or could hear the I/O idling over the noise from the two cycle kicker.
The steering system I believe you are refering to is an ez steer system.

My wife would not let me spend the $250 to buy one, so I made my own.
