Definitely, in NZ and Aussie 'gearbox' and 'transmission' are interchangeable terms...

As for the old direct drives with NO metal gear thing, it was surprising how quickly stopping the engine, flipping the cam cog and starting the engine can be done. Most of the engine are slow under 300 RPM so they stop fairly quickly, and there was a lever, chain/cable to the cam cog. May be a couple seconds longer than boats with the gear thingy as it has to slow enough before shifting.

Still, it must have been very difficult to negotiate a tight marina with that system.

So my husband was a sea scout and I don't know the details but the boat had to be shifted from forward to reverse in the engine room. There were some levers at the helm that the helmsman would move back and forth to indicate what we wanted the person on the engine room to do. They make some kind of "Ching Ching" noise and the person below repeats the message back to show they received it correctly. They were coming into a marina in San Francisco and the helmsman sent the signal to change from forward to reverse. The engine room responded but the boat kept moving forward. He signaled again "all reverse full". The young sea scout in the engine room was confused and thought the message was "all ahead full". They ended up crashing into a docked submarine. true story.

Yes it is, but they tend to be mooored in commercial areas/docks, so pumping and banging into each other is not a big deal. You should see them come up against a dock. When they came in a little to fast/hard we sat down on the dock because you would be knocked down. Well, first we ran as safe distance.

Last night my wife was watching a 70+ ft steel converted tug dock, it had a gear box, has a dozen tires hanging from the siide and he came hard against the dock. She wachted for quite a while, so I asked her what was she was watching, "Oh, just the tug docking." Followed by, "We should have a couple young male to crew and help us dock." I looked out the window and two 20-30 ish males where tucking and pulling on the line. Ha right! Waching the tug boat dock? !

Its not uncommon on the larger pleasure and commercila docks that other come help to line in the boat as we know what a puckker factor docking can be.

Docking help is great and I personally appreciate it but some folks have posted on this forum that they don't want anyone helping. To each his/her own, I suppose.

There's a guy a few slips down from me who is so particular about docking or casting off that most of us hide in our boats when we see him coming. Being yelled at is a big disincentive for helping.

Although it may not be "correct" I have always considered the marine gear or transmission to include both a clutch and reversing gear.

It can include reduction gears too ,tho many boats with a CPP setup will have only reduction gears , no clutch.

The prop is selected FWD , no thrust or REV as required.

In the UK we always say "gearbox" when referring to autos, unless talking about a "rare" automatic vehicle, when we will say it has "automatic transmission", although I left the UK 20 years ago, 99% of vehicles had "manual gearboxes", what you guys call "standard",
so it's really just the terminology, you use "trunk and hood" they use "boot and bonnet".

I've been in aviation all my life, I now work for Rolls-Royce building and repairing jet turbine engines, all of which have a "gearbox" attached!!!, hope that doesn't complicate matters even further lol.
