Marine 6.5L Diesel engine - "Peninsular"

A proven marine diesel engine platform created by Peninsular Diesel in the 80's and refined throughout over 20 years of service.

This is the engine sold for many years by Peninsular Diesel Inc. and is found in many configurations and HP levels. At present time this complete engine configuration is due to be available again but due to the transition of components to Unique Diesel will take time. Replacement Marine 6.5 longblock engines are available now if you need a replacement to use with your existing marine hardware accessory gear. Please contact us with your engine needs and and we'll work with you as best we can. Please re-visit this page for further details as they mature.

Please Note: Please contact us for factory refurbish options for existing Peninsular owners and for any parts needs you may have.
