I think the sail master series has a modified prop or thrust more designed for sailboats as the name suggests. Usually long shafts as well but might do the trick anyways. I’ve heard others say 8-10hp high thrust. I put a 9.9 Nissan on as my kicker, it’s a 20” shaft and a little long so 15” would probably be better for me.
had a sailmaster on my sailboat for years, great motor, differant gearing big prop, would be an excellant kicker, had a generator so it will help keep battery up
where the bracket is placed on mine, the 20” shaft seems too long just based on the cavitation plate for the lower unit where it sits in the water. I have the bracket on the highest setting, and the motor tilts down and it’s still sitting a little low, so I don’t put the bracket down at all. I see what you’re saying about the side to side rocking though since the kicker is sensitive to that with its placement. I guess I’ll take another look at mine.

I have a 22’ sailboat with a 6 hp 25” and a 9.9 hp 20” for the 20’ overnighter. Both are about the same weight ~3500lbs (not planing so displacement hull speed) and I never get close to maxing the revs on either engine.
