when you remove the bracket the motor will slightly drop to that side. Just need to fill the gap with something.
I'm pretty familiar with that boat.
Tilt the motor completely up, set the trailer brkt (port side). undo 6 bolts holding trim into brkt, operate trim down, motor will stay up on brkt, trim will raise itself up towards trim pin.
try to swing trim assy from between brkts and you will see how much room you need. Looks like it will almost come out but it doesn't.
than you block to the tilt tube, back off tilt tube nut,unbolt stbd brkt and slide it to stbd until the trim assy pivots out of brkt.
at this point you can reinstall sbd brkt if your nervous.
