Inboard Engines

YM Series NEW 3YM30 (29HP/21kW) More displacement, more torque, quieter, cleaner running and featuring an all-new three-cylinder block and combustion system. This is the latest in high output marine diesel technology.

The 4LV proves to be an extremely efficient engine without any compromise on quality. Featuring the newest system in common-rail technology, the mid-range engines deliver maximum performance and reliability, while maintaining minimal fuel consumption and exceptionally low noise & emission levels. By exceeding the strict EPA Tier 3 and EU RCD Stage 2 emission regulations, the engines feature virtually smoke and odor free operation. Equally, the 4LV doesn’t disappoint in performance. The 2.8 L displacement delivers a powerful low-end torque performance. This results in a stunning acceleration and really sets these engines apart from others in their power range. To ensure support of advancing marine technologies, direct connectivity to NMEA and J1939 CAN-bus networks has been purpose engineered into the 4LV range, allowing future-proofed integration to any multifunction bridge display.

The 3-cylinder 3JH40 has been developed by leading manufacturer YANMAR as the marine industry’s smallest CR inboard diesel engine. With an output of 40 mhp, it will enable a whole new category of smaller leisure boat owners and commercial vessel operators to benefit for the first time from the efficiency and performance advantages associated with the most recent electronically-managed CR fuel-injection technology.

A high-displacement footprint allows the V-8s to work smarter – not harder – with lower max rpm to ensure longer engine life. Engine Guardian is standard and averts potential problems with timely intervention, while the Cool Fuel Module prevents vapor lock. Long runner intakes pack more air into the chamber, while the advanced MPI system fine-tunes the fuel-to-air mix, producing more power on combustion. High performance aluminum cylinder heads improve mid-range acceleration. Optional SmartCraft® Digital Throttle & Shift provides silky-smooth operation.
