What Is the Keenan MK60DP EFS Fuel Management System?
A compact dual-filter diesel fuel management system perfect for small to mid-size engines. The full-feature MK60DP EFS offers everything you need to keep fuel clean and motors running smoothly — including continuous fuel polishing that removes water, sludge, and particulates before they ever reach sensitive injection components.
- Dual filters + EFS remote switching — change elements on the fly without shutting down
- Integrated pumps for bleeding, priming, and backup to engine’s lift pump
- Remote warning panel alerts the operator before issues reach the engine
- Uses common Racor® elements for easy sourcing and service
- Optional pressure transducer for vacuum monitoring & data logging
- Optional GSM interface for remote monitoring
- Machined aluminum & stainless construction for marine durability

Why Advanced Filtration & Polishing Matter for BETA Marine Engines
Modern diesel often contains bio-content that accelerates diesel bug growth and water absorption. Contaminants clog filters, damage injectors, and can strand you offshore. Combining Kubota’s clean-burn technologies (E-TVCS indirect injection; E-CDIS direct injection) with Keenan MK60DP EFS filtration delivers:
- Longer engine life — fewer abrasive particles reach pumps and injectors
- Reduced downtime — hot-swap filters without stopping engines
- Cleaner emissions — stable atomization and consistent fuel delivery
- Lower total cost — fewer injector replacements and emergency callouts
Kubota E-TVCS & E-CDIS: Clean Combustion by Design
E-TVCS (Three Vortex Combustion System) creates optimal air/fuel mixing in a swirl chamber for quiet starts, low smoke, and good economy. E-CDIS direct injection raises efficiency further for the BV3800 platform. Both systems rely on clean, water-free fuel to maintain injection precision — exactly what the MK60DP EFS supports.
