Firstly, Welcome to ribnet!
Reading between the lines I guess you want to know if it's feasible and / or howe to do it? The guys above have answered the first, so here's my take on the high level side:
things you will need:
1) a console or dashboard type arrangement to fit the steering wheel & engine controls to.
(I assume you have this on the new boat, hence your Q so won't say any more)
2) steering wheel & steering cable to connect it to the engine.
(Again, there;s a high chance this will be fitted to the new boat?)
2a) Something called a "drag link".
This is a bar that connects the end of the steering cable to the front of the engine, usually just below the case
3) remote throttle / gearchange - AKA "remotes". Probably habve a deadman switch built in, unless they are really old.
3a) If no deadman switch in remotes, a deadman switch.
4) Throttle / gear cables (bowden type - no electrical)
4a) if not "Tohatsu" or "dealer supplied" cables - you'll also need suitable end fittings to connect to engine's gears & throttle.
5) A couple of hours or so to connect them all up.
I would guess that as it's a new rib, the steering gear & cables may already be part of the package? If so, then you can either go to your dealer & pay a lot for the appropriate Tohatsu remote control kit, or find some used bits & cobble it together.
(The one good thing about remotes are that the cables themselves are a universal standard, so you can probably save a bit by using Ultraflex or Teleflex cables with their Tohatsu end fittings.
One thought - what is the max HP your Rib will take? If >18Hp, do you plan to upgrade? I ask because if you sddo think more gee gees could help, it might be worth future proofing, and get electric start / PT equipped remotes for when you upgrade the engine.
