Official Yanmar 6HY commercial marine diesel engine

The 6HY is Yanmar’s heavier commercial six, the continuous-duty engine built for the boats that work for a living, from ferries and charter fleets to workboats.

This is the deep-end work we’re known for. We rebuilt fourteen Sydney Ferries engines in ten months, and commercial power is where we’re at our strongest.

Who it’s for: Commercial operators running a 6HY-WET or 6HY-ETE, ferries, charter fleets, workboats and hard-working launches.

Phil’s tips

Straight from the workshop

Tether the key to the sea cock

If you close the sea cock for the engine every time you leave the vessel, leave the engine key tethered to the sea cock handle. You physically cannot start the engine without opening the water first.

Let it warm up

Always let your engine warm up before working it. A few minutes at the dock gives the oil time to circulate, and you will get a better service life out of the engine for it.
