The power behind boats
Darwin has become a hub for Steyr Motors in recent years, being the power plant behind the Zodiac RIB tenders on the Australian Navy Armidale class of vessels.
The RIBs see a substantial amount of action, particularly in their use as border protection and asylum seeker retrieval vessels.
Under a previous agreement with the Australian Navy, the Nine Network’s hit television show, (now finalised), featured two Armidale class vessels during its filming.
In real life, the Armidale class of vessels carry the Zodiac 733 RHIB ribs and are fitted with the Steyr MO256K, 250Hp.
While Steyr Motors is perhaps better known for its commercial engine business, the company also offers engines for the marine pleasure market including shaft and stern drive models.
In virtually every instance the basic engine is the same; and the drives are Mercury Marine — the Mercruiser Bravo I, II, or Bravo III.
The Steyr Mono block engine family consists of several design solutions which provide high power density, reliability and safety in operation that are designed and built especially for Marine applications.
Steyr Motors offers special design features such as robust cooling, a single-cast engine block of high tensile alloy, a free cylinder liner, valve seats from Stellit material, inserted valve guides, a high pressure mechanical Steyr Unit Injector, and the lowest weight and compactness in its class.
Steyr Motors has a range of four cylinder and six cylinder engines in the Stern drive category; the four cylinder range has just the one model, the MO174V40, which is turbo- charged, intercooled and direct-injected, inline 4-cylinder, 2133cc that develops 170hp at its maximum4000rpm.
A solid choice when reliability and power is required
