General information: Engine condition unknown, sold as is as shown in the pictures. Specifications provided are for general guidance only and may contain errors.
This ASM184 is delivered mounted on a stand along with five wooden pallets of spare parts. The engine is not complete, it is sold for restoration or spare parts and its condition is illustrated by the pictures.
At one time it was modified to Swedish specification 184C by the "Centralverkstaden för TB motorer" for use in some of the Swedish Navy's 20-meter T21-T31 torpedo boats manufactured by Kockums in 1942-43, 23m T32-T41 (1951-52) and later 23m T42-T56 (1956-57). As an example, the 40-ton T32 torpedo boat had three ASM 184s with a total of 4500 hp and could reach a hair-raising maximum speed of 50 knots (92 km/h, or 58 mph).
Technical specification: ASM 184 (also called IF 184) W18 has 18 cylinders with a total displacement of 57.3 liters, four valves per cylinder, six carburetors, dual centrifugal superchargers and can produce a whopping 1500 hp at 2000 rpm.

A brief history of the Isotta Fraschini (IF) W18: The ASM W18 engine was a further development of the iconic IF Asso series of aircraft engines designed by Giustino Cattaneo at the request of the Italian Ministry of Aviation in 1924. The first 500 hp V12, the Asso 500, was successful and paved the way for the Asso series developed in 1927. The most successful engine in the series, the 750 W18, had its most famous application in the Caproni Ca.111 reconnaissance aircraft, the largest engine in the series, the Asso 1000, was the series-produced version of the 1800 hp Asso 2-800 racing engine which was specially developed for the Macchi m.67 racing aircraft for Italy's participation in the Schneider Cup in 1929. The world's largest land aircraft in 1929, the Caproni Ca. 90, was powered by six Asso 1000s and set six payload records on 22 February 1930. Later, around 1933, the Asso 1000 began to be used in shipping in the models ASM 180, 181, 183 and 184 (ASM stands for Asso Marini).
