Specific type of the engine, because of high cylinder capacity even with only 30HP and sharp torque curve, can use big diameter props and push very heavy loads. Dry weight 270kg

30HP at 2.600 rpm
With KH18 Gearbox Ratio 2.03

As any our unit completed in "peace of mind" style. A lot of photos of an overhaul process available.

Somebody will get nice Toy for his beloved Sailing boat or Motor yacht :)


Engine is in "as new" overall condition and ready for thousands of hours to go...

Solid thick liners (standard size of 88mm) allowed to rebore them to oversize of 90mm which will supply an extra +HP because of bigger combustion cameras

Following brand new genuine Yanmar parts were installed (last photo):

standard size of 90mm (ZTR20A) pistons with rings,
standard main and conrod bearings on crankshaft (which was found "as new" after checking of wear limits),
3 exhaust and 1 intake valves, all internal Anodes, some valve guides, all gaskets, oil seals, filters, bearings, belts, injector valve nozzles, water pump kit including shaft and impeller, water & oil pipes, thermostat, all engine mounts, clutch disc/damper, SS belt cover, SS dash panel with RPM meter, all new wiring harness.

Unit is filled in with antifreeze to avoid any internal corrosion.

Some break in hours on low/mid revs/load would be very welcome and required to ensure longevity of this unit.

No problem to deliver Globally to any destination via air, sea or road freight
