My 84 is a 23.5 inch. It is a factory 20 inch with a plate put on to use a 25 inch motor. But they didnt make the plate tall enough, its about 1.5 inches short. It looks like that was as high as they could go and still bolt the motor to the original transom.
I will be putting my 20 inch Johnzuki on here in a few more days.
