The versatility of the Cummins QSB6.7 Marine Engine

An interesting week in the workshop converting a Cummins QSB 6.7 propulsion engine for a customer. This project involved converting the voltage from 24V to 12V, increasing hp with an ECM calibration from 355 to 380hp, installing a new flywheel housing, and incorporating a high rise rotatable exhaust. Interested in using a Cummins engine for your next re-power or new build project, please give us a call. We have QSB6.7 slimline and standard models with various horsepowers, QSC8.3 and QSL9 all available from stock. And, don’t forget we hold extensive stocks of Cummins parts.
