Don't know what to keep looking at, engine,boat,engine,boat. Both beautiful pieces of work. Could someone please explain what the silver painted unit is between the seats? |

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

Thanks for that, I have heard of them mentioned here, but didn't know what it meant. Look forward to more info.

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.
Here is a link to the Dispro Club home page:

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.

Yes- really well done - life finally seems to have gotten out of the way for you.
You'll find that it will start and . . . GO
It will be no slouch even with 2 or 3 passengers.
So you will need to make sure you've got it aimed where you want / need to go.
Not a put-put , but more of a PRRRRR with the 2 cylinders even at slow sped.
Congrats . . . .miro |

Mike Windsor suggested wiring the ignition so you could shut off one or the other cylinder for slow speed maneuvering....so I did |

Twin cooling has always been an issue. I've heard lots of people putting restrictions in the cooling piping to try and mitigate. I found running this on the bench with a manifold and single carb the rear cyl heated significantly. Apparently gravity feeds more fuel to the back cyl and it heats up a lot. I put two carbs on to run like two singles and they ran within a half degree...hopes it is the same in the lake! |

I have a Dippy with a Waterman K2 twin running with zero cooling issues for 20 years. Putting your hand on both copper jackets show no detectable difference. The last year the boat was used extensively it started on the first pull all summer.
I have restored two k2 Watermans which did not show any heating tendency its a GREAT engine

With the Adams, mind you it is single cylinder, to approach a dock I can slow it down most by bringing it back to idle, then blipping the ignition switch on and off. That was how it was done with WWI fighter aircraft with rotary engines. I'll switch it off, and as the flywheel is close to stopping I'll flip it back on and the engine restarts. With a little practice it becomes quite easily done and is very effective.
Also, with the Adams, presuming the problem is not a water pump check valve that has hung up, I find the engine runs cooler if throttled back abit. I am always careful not to run it too fast anyway but in warm water conditions it is possible to generate more heat than the water pump can remove. It is never a problem in the spring, but is notable later in the summer. A slight rpm reduction is all it takes to manage that.

Once the gremlins were identified and tamed it starts and runs beautifully
