Protean Design is happy to advise all customers past, present and future, that we have acquired the name, production rights and website of Prop Shop.

Welcome to the updated website of products from a trusted name in marine modelling for over 30 years.

Can I still buy matching props to older Prop Shop designs? Many will be aware that a lot of moulds and patterns were lost in a fire under previous ownership. We have some stock of older castings which will be supplied where possible to match missing props. Generally though, we have had to start afresh building up a range to match the huge variety that customers have come to expect. The new moulds include improvements in design and production, giving generally lighter and more efficient propellers which are easier to balance and finish. They may not always exactly match older types.

What has not changed is the exceptional quality which singles out Prop Shop from the competition. We continue to use the lost-wax casting process as it’s the only way to make efficient and strong propellers in quantity. Various grades of marine bronze are used for toughness and corrosion resistance. Aluminium props for racing are also supplied, and stainless steel will be available too. All props are balanced and finished as standard.

This website features the main categories of our most popular products from scale to high speed props, shafts, couplings and other fittings. If you need something that’s not shown here, just call or email and we will quite likely have an unusual pattern or quote for making it.

Postage costs: For now Royal Mail first class is the normal method, or airmail for overseas. Where possible we will post as ‘Large Letter’ for £2.00, otherwise, as a small parcel, the cost will be £4.00. Special services, bulk orders, airmail etc. will be charged pro rata.

Reference Numbers: Those familiar with the old inch-based system for scale props will notice that all part references have been harmonised under a millimetre system. The first 2 or 3 digits give the diameter in mm, the final 2 digits give the pitch / dia. ratio. for example ‘5011’ is 50mm dia. with a pitch ratio of 1.1. Then /2, /3 etc. gives number of blades. LH rotation is anti -clockwise and RH is clockwise, viewed from astern.

Threads and shaft fitting sizes: Default threads are metric coarse pitch in proportion to the prop size. From 8mm to 25mm, that’s M2, from 30 to 60mm M4, larger sizes M5. However, any thread including BA or UNF can be supplied on request, just ask. Smooth bore dog-drive props are still widely used in racing boats, so 1/8”, 4mm, 3/16” or ¼” dog-drive will be supplied as appropriate.

STANDARD SCALE PROPELLERS For realistic scale models, miniatures, runabouts, tugs etc. of all kinds where the exact prop style is not known or not critically important, these will work efficiently with brushed or brushless electric motors. The standard pitch ratio is 1.1 (fine ) for low current draw with a good, usable speed range.

PERIOD / VINTAGE SCALE PROPELLERS have the same pitch ratio as standard scale props and the same efficiency, but are used where a specific style is needed, especially WWII pattern with the distinctive pointed boss and rounded blades. This type is now available from 8mm dia. to 95mm.

STEAM PROPELLERS have an early period blade profile, with an unusually high pitch ratio of 1.5 and cambered blade section, giving the best performance with slow revving motors or steam engines. Where previously we only made these in left-hand rotation, all new steam props come in both left and right-hand.

Please note that propeller rotation is based on the British and American standard (viewing the boat from the stern) which is the opposite to that in Germany.
