bracket

are deadrise and transom angle the same thing

No deadrise and transom angle are very very different measurements . . . Transom angle was 12 or 13 degrees when I built my bracket, but 1 or 2 degrees off will not matter.

The Spec sheet does say deadrise degree (measured at transom) I misinterpreted it, sorry about that. I now understand that the deadrise is the angle of the sharpness of the bottom of the boat (v-bottom). Therefore a flat bottom boat has a deadrise of 0 degrees. I did measure my transom angle on my 18sf and it turned out to be about 15 or 16. Which coincidentally is the same degree deadrise listed on the spec sheet. sorry about my confusion, good luck

No need to shim. The 17 degree bracket will work. My 72 20' Seafari is 14 degrees transom angle. My neighbor's '84 20' CC is 15 1/2 degrees.
