That's a disappearing propeller unit, better know as a Dispro or "Dippy". Let's see if Miro will come on board.

I love the boat and the engine but what make is the engine with brass heads ?? and loved the explanation of the hidden propeller what a novel idea. Wish we could get more of the old engines in Australia wonder what the freight would be

These engines went through a few name changes, I believe it was Waterman, Arrow, Pausin, and then Dispro made their own version, but I don't know if they made a twin. The Dispro had a larger displacement. The cylinders are cast, the outer water jacket is spun copper. Nice looking engines and light weight.

Yes siree that sure is a new DisPro.
I guess at one time all of them looked somewhat like that - all new and shiny. Really good work !

Most of them today look their age and need the care and attention to keep them going.

The DisPro's equipped with 2 cylinder Waterman engine run smoother than say a 1 cylinder St Lawrence, and they go like lightning.

Altogether there were about 2300 made between 1918 and 1956 when production was stopped. Today about 280 survive but new ones are still being built be enthusiasts.
You've got to be an enthusiast to build one - it sure ain't easy or simple.

There is a hull mould that was made about 15 years ago and has gone through 3 or 4 owners now.

Have a look at Mike Windsor's project. I've seen this boat in the water with 7 people on board and it runs like the wind. From the pictures, you'll appreciate the complexity.

Here's another web site that gives a good background and description of the DisPro.

A beautiful looking craft. A lot of work gone into her. Like the disappearing propeller. Our way we use pull-up in the dories. Most of the pull-up boxes, the engine had to be stopped and the 2-wing blade vertical, in order for it to retract. Some pull-up boxes were big enough for the propeller to be retracted when running (such as running over a surface net on a foggy day). Use to be very noisy with the propeller and her wash in the pull-up box.

Great job!
That must have been some catch to get a K2 and device with an aquascope.

Engine is not a Waterman K2. It is a Dispro D2. A Waterman in a Dispro boat would have a round top device and no aqua scope. The device and engine pictured is a proper combination.

That strikes me as odd then, as this looks like a pricey upgrade to a boat that was marketed as accessible to everyone and utilitarian. Sort of like getting a leather interior in a Ford F150?
How much more cantankerous are the 2 cylinders to operate?

My experience with a 2 cylinder vs a single cylinder copper jacket engine (DisPro's) is that the 2 cylinder engines are a challenge to get running right in terms of engine temperature.
If the rear cylinder is running right, the forward cylinder is too hot and make backfire. If the forward cylinder is right, then the rear cylinder is too cool and will mis-fire.
It IS possible to get them balanced but it means inserting a restricting washer in the water flow between the 2 cylinders.

If you've ever been in a DisPro, with a 2 cylinder engine that backfires, you'll never forget it - at least I won't. It's dreadful, terrible BANG. With a single cylinder engine, it's more like a sneeze.

But it's a good looking boat in the hands of a caring , thoughtful guy.
