Well, since no one has chimed in, I'll add my .02
Since the CS20 boats have good freeboard, you need a way to have the motor lower, but you already knew that. The Suzuki, like most other mounts, needs space when you tip it forward. Even though the tiller tips up, the motor itself needs some clearance. This makes it so that the bracket has to have a lot of room, or spring up so the motor is above the transom. Both ideas have problems.
In the long low bracket, with enough room for the motor to tilt, the weight is aft which isn't great. You can scooch forward to trim the boat, but it's amazing sailing in the company of others how many boats are dragging the transom.
In the popup bracket, the motor in it's raised position is high, raising the CG........where you also don't want it. You will need to remove the motor during travel with any bracket.
I believe the best option is to study the pages where integral mounts were made and design you own. Here is mine:
That is the start of the area of where I started and follows over a few pages.
I stole Graham's idea from Carlita but at his recommendation put it on the Starboard side. It wasn't that hard and the results are excellent. I did start out with a short shaft and I failed to realize that if I went forward the motor would be a bit starved for water and the exhaust would be above water. I converted to a long shaft by buying the parts. If I had to do it all over again, I would have cut the mount in a few inches lower and called it a day. When I sailed in the company of @amos I noticed his short shaft Suzuki 2.5 was fine.
The results are a sturdy place to keep the motor while trailering, and a low CG close as far forward as possible.
I hope this helps.
