To place the bracket on your boat you need to see what motor you have, 20" 25" 30" thats the first measurement you need. Now put the bracket at the point on transom were the top of mounting plate is at your engin height.now add 1" for each foot back you are going.

So you say you have a 20" and going back 28" thats comes out to22" and you should be fine.

But I hate to say it but a 20" on a bracket is way to low, its going to get swamped with water every time yo stop and waves are splashing it, min I woud go is a 25" but the best is a 30" on these boats, been there done that. mine was a 25" always wished it was a 30".
