There are two main ways of inflation--either a foot pump (hand pumps are too hard on the back) or electric pumps, off the 12 volt battery. We carry both types. We have a LVM 12 volt pump which I purchased in the 1970's and it works as well as the day it was new. Not the cheapest, but in the long run and excellent pump. There are many cheaper, and some are quality, and some are for toys, like pool floats.
Yes, they have been inflated by mouth--but I can testify that it is not easy. There used to be a "Great Avon Race" at the Isthmus, Catalina Island. We came in second several years--and one of our tricks was to have the one allowed pump, and then at least one other blowing into the tubes. (Red Seal--no transom type of inflatable)
Since you have the 2 hp--use it. It makes a good dingy motor. I prefer the ones with manual clutch. Yes, they are fairly easy to put on top---even for one person, with the lighter boats.
