Transom angle for outboard bracket

[ChrisC]

I just measured the angle on my 20' Seafari transom so I can start looking for a bracket. I came up with 13 degrees and I did take a few different measurements on different places and came up with the same number. Does 13 degrees sound right? Has anyone got a different number? Any info would be great. Thank you

Although I don’t have a bracket on my boat over the years people have said that the 13 degree angle with a 30 inch set back on a twin flotation bracket is the way to go.

13 degrees is right. Single or twin, I would go with a 30" setback. It allows you to mount the motor higher, and also puts the prop in cleaner water. The hard part is the bracket mounting height. I would suggest mounting the bracket as low as possible to get the max floatation at rest. When your running, the bracket is completely dry.

Then mount the motor high on the bracket. If you mount the motor at the perfect height for cruise, it might be a little too high for WOT, if you mount it for WOT, it might be a little low for cruise. Even fuel/occupancy load will change. If I have 4 people, a full live well, ice/fish, and a full tank of gas, Mine is mounted a little low, 2 guys, 1/4 tank of gas, empty live well at WOT, I am a little high.

It is hard to get it perfect for all loads/sea conditions.
