The picture is small but it says: "Stainless Steel Shaft with Nickle Plated Brass Tube and Brass Bushings."
I would take that as being a solid shaft.
Graupner makes flex couplers, dont know what size you need... http://www.offshoreelectrics.com/pro...?prod=grp-3344

These shafts are designed for scale boats with slow revving motors, hence the brass bushings.
If you use a flex coupler and put stress on the inside bushing, it'll wear relatively fast and will start to rattle and leak.
If you only run the boat every once and a while that's no problem, 'heavy' use will result in the above situation.
I'd rather go for a 'real' flexshaft and strut/stinger in that case.
