Anyone with a good idea to make or buy an outboard bracket for an SB20?
Many thanks

Are you on Facebook, there seems to be an SB20 group you could perhaps ask?

It seems to me from the pictures that SB20 has cut away transom so actual transom is limited height. You would need to add the bracket about half way from rudder to hull side. Close enough to centre for manageable thrust but far enough away from rudder to not impede movement or hit prop.
The bracket can be complex with ability to raise the level. However a simple bracket can be made from angle steel or aluminium. You need of course a block of ply wood to mount motor. Angle metal each side to match angle metal attached to the transom. These are joined by 4 pieces of angle or flat mounting the wooden block at a suitable distance from the transom. Not so close that you can not clamp motor not so far that it over hangs too far. The over hang leverage will be the problem with such a low height transom to attach to. You need then 2 flat strips to triangulate the mount once you have decided on bracket height. Not so high that motor can cavitate on waves or a person on bow picking up mooring. Not so low that motor might get swamped or drag too much. (or be too difficult to get out of the water when you swing motor up for sailing.(hence the value of an adjustable bracket) Just need bolts and nuts to hold it all together. ol'will

Actually after a rethink on this question I realise probably advice ok for standard transom but not for the SB20. Now I am not sure how much actual transom there is if any and how high it is above water. A very simple answer might be to bolt a block of wood or stack of ply vertical on the floor at the back edge. You might get away with long bolts in to floor or need some sort of triangulation structure from the block to the floor forward. If that height does not suit then you will need a bracket to go out and down to get lower or mount on a higher block on floor.
It will probably be impossible to get nuts on the inside of bolts into the floor. If GRP of floor is thick enough you may get away with tapping a thread in to GRP. Or if necessary glue and bolt (tapped hole) a plate of GRP or wood of larger area to take mount block or bracket.
In any case a long shaft motor might be needed. It is all a question of height. ol'will
