Changing a BF45 Powerhead mid 90's

[Timmersramos]

I have 2 BF45s, one with a bad lower and trim and one with a stuckhead but good trim and good lower. Should I swap powerheads or leave the powerhead and swap the lowers and trim? Do all the bolts inside the lower cowl need to be removed to free the powerhead? Any thoughts. thanks T
