The propulsion of Idefix comes from a single diesel engine. In the future I wish for electric propulsion or at the very least a hybrid solution to avoid using fuel whenever I move.

Ford Lehman 2704 ET

Main (and only) engine of Idefix. A 6 cylinder turbo-loaded diesel engine from 1976. Displacement ~6 litres. Motor block built by Ford, marine converted by Lehman in the UK. 12V starter motor and generator. Drives a straight shaft connected to a Borg Warner Velvet Drive reverse gear.

Borg Warner Velvet Drive

Reverse gear operated by wire from the main cabin. Gear ratio supposed to be 2.1:1 but I've never measured it. Works on same lubrication oil as the main engine.
