I have a 2021 15hp pro kicker that has 3 year warranty remaining. It'll be coming off my boat shortly. Could come with/ out controls and harness. Had a full end of season maintenance in October at rpm. I managed to get my mitts on one of the new 3cylinder 25s they got in.Ya I have already asked if they have any decent used 90/115 and getting a 9.9 kicker. I had a legacy lodge 17.5 fiberglass with a underpowered 60hp Yamaha previously and hated being that sluggish so not wanting a repeat of that.
I don't know if you'd want the extra weight of a kicker with the 70 though. The 120lbs might impact the already bad performance. I wouldn't want to be on the ocean with a 2500h motor without a kicker though.... Tough one.
