This part of the range concentrates on the five and seven blade scimitar props of modern submarines, both diesel and nuclear. It is not possible to include every propeller we have designed in this category (we have made many specials) but if you don’t see what you are looking for here, please enquire. We may have the prop you need.
The typical thread types for these props are M2 (for very small props), M3, M4 and M5. You can specify another thread type if you know exactly what you need.
For this range, the reference number indicates the diameter in inches: Eg, the SC28 is 2.8" dia.
