After a few days of expermenting, my back hurts, my arms hurt, and another part of my body has a pain in it the several occasions of nearly falling in the marina hanging on to the mercury

Hlb you are right, get the smallist dinghy posible and a nice small outboard.

Have messed around with a mercury 5hp 2 stroke and a 3.6m inflatable
Mind you did get one good thing from it, the LVM hi-speed inflater/deflater is good

Thanks to everyone who commented in the original post .

Any good recomendations on small inflatables ?//
