Live Steam
Quad Cylinder "Marine" Model Steam Engine
Fully Machined Kit in Brass, Bronze and Steel
The vertical four or quad cylinder "marine" engine is two twin cylinder marine engines connected via a large flywheel on a steel plate, top brace plate and (optional) inlet manifolds.
As such it is still relatively simple and retains the basic mechanics of engines which powered ships and larger boats which needed the extra power provided by a quad cylinder engine.
NOTE: Pictures are of the assembled kit, this listing is for the kit of parts. Also shown is the optional manifold.
The marine engine layout has four double acting cylinders, eccentric driven piston valves and the brass flywheel offers smooth running and is capable of powering a range of accessories, in a variety of roles. The engine also includes 2 x triple split bronze pedestal bearings for the crank shaft, tube sliders and a substantial cast base.
On the two twin crank shafts, the cranks for each cylinder are offset by 90° which means the engine will self-start in any position.
The engine will run in reverse by applying the steam (or air) input to the outlet ports.
The kit consists of precision produced parts each carefully made and checked to ensure ease of assembly and reliability in service.
The cylinder assembly and piston are manufactured from brass and the piston shaft, connecting rods, column screws and valves from stainless steel so are not susceptible to corrosion. The piston shafts passes through an adjustable glands and the steam inlet can be either side of the chests.
There is also a 15mm taller version of this engine based on the standard marine twin.

The kit consists of a set of fully machined parts that can easily be assembled using simple tools such as a screw driver, allen keys, pliers and metal file. The parts are mainly unfinished metal and will also require painting, polishing, filing, etc.
NOTE: The kit is supplied with socket or hex head set screws (as per the pictures), although some screws for ease of installation, have to be socket head screws. Some screws as provided may need to the cut or filed to length to complete the model, contact us if this will cause a problem.
When assembled the engine is fully working and can be run using steam or simply using compressed air e.g. from hand or foot pumps.
To power the engine with live steam, connect it to one of our Model Steam Boilers.
