If your area is in a Seatow or Towboat service area, that’s your best bet.
Every boater should have a membership to one or the other (or both).
It’s too cheap not to.
That, a functional VHF and good ground tackle will be your safest fallback.
If something does happen, you’ve got the bases covered. Drop anchor, hail CG on the radio and be safe until help arrives.
Personally, I feel a kicker of suitable size for a 27’ doesn’t seem practical. I’ve tried to maneuver my 3000 using the dingy w/9.9 as a power source and it would barely make headway and all bets were off if there was any current or wind.
WRT storage, there aren’t many convenient places to store an outboard. ER isn’t an option on a gas fueled boat/motor, same with the cabin, which leaves a bracket somewhere external which would probably be in the way no matter where it’s mounted.
