As Charlie said putting the outboard on the boat isn't that difficult. When I had the Mercury fitted on Sweet Honey it took the guy less then 4 hours including a general service.
From what I can see from the photos, the steering rod is fitted already so all you have to do is put the engine on the transome and route the control down the side (maybe have all the cables within reach before mounting the engine).
The control cables shoudn't be any problems, more light normal electrics a matter of putting them down and tidying them up. Then you have the rev, trim, volt,.. counters which I believe the electrician will do. All that is left is the engine.
To mount the engine you will need an engine hoist, a drill, tool box and possible a lifting key from Suzuki, my Mercury needed a large 'bolt' with a ring on top. It's purpose is for the hoist to hook into.
Actual work involve is pretty minimal, you have to lower the engine on the transome mark out the fixing holes, drill the holes, lift the engine fit the steering rod and finally lowering the engine (you may want to do a dry run before any drilling and bolting), bolt on the bolts, seal around the hole with silicon. Finally connects all the electrics and fuel line and hey presto done. It really is that simple, however, it's easier if you have someone with you to help move the hoist as well as passing tools etc. It also helps if you are fitting it on a level drive and not a slope, which I did. . Wouldn't mind helping out if you intend to fit it on a Tuesday.
