Features:
1. Superior combustion performance
The unique Yanmar swirl precombustion chamber combus-tion system and new cooling system display superior combustion performance in all types of operation. Low-speed, low-load combustion performance, especially demanded for marine applications, is also superb, and stable performance is maintained over a wide range of speeds. Since starting characteristics are also excellent and warm-up is fast, full engine performance can be obtained within a short time.
2. Low operating costs
Excellent combustion and low friction reduce fuel costs. while the optimized piston shape and ring configuration and improved cooling system reduce oil consumption.
Continuous operating time has been extended and operating costs reduced through improved durability.
3. Compact, lightweight
The cylinder head is the integrally-cost type, and the crankshaft is the housing type. Minimum weight has been pursued for each engine part, and a reduction reversing gear employing a special new mechanism has been incorporated to obtain revolutionary engine lightness.
4. Long term continuous operation
Improved durability has been achieved by adopting special construction and materials for main moving parts and the valve mechanism, which are the areas most subject to trouble in high-speed engines. Moreover, a bypass system with a thermostat maintains the cooling water at a stable high temperature, resulting in reduced cylinder liner and piston ring wear, reduced thermal load around the combustion chamber. and substantially improved durability. Long-term continuous operation is possible by correct operation and proper attention to fuel and lubricating oil.
5. Low vibration
Vibration has been reduced by minimizing the weights of the pistons, connecting rods, and other sources of vibration, stringent weight management at assembly, and balancing of the flywheel, V-pulley, etc. Vibration has also been suppressed through the adoption of a special cylinder block rib construction and improved rigidity. Rubber shock mounts are available when the engine is to be used under conditions which may lead to severe vibration.
6. Quiet operation
Intake and exhaust noises have been lowered by adopting an intake silencer, water-cooled exhaust manifold and water mixing elbow type exhaust system.
The precombustion chamber system and semi-throttle type injection valve suppress combustion noise substantially.
Moreover, gear noise has been reduced by the use of helical gears around the gear train and clutch gear, and by the buffering effect of a damper disc.
In addition, noise prevention measures have also been taken at the control valve mechanism and other parts.
7. Superior matching to the hull
o Four point support engine installation feet make installation easy.
o Mist intake system prevents contamination of the engine room.
o Since the fuel pump is mounted on the engine, the fuel tank can be installed anywhere.
o Water-cooled manifold prevents a rise in the engine room temperature.
o Independent type instrument panel can be installed wherever it is easiest to see.
o Speed, clutch forward and reverse, decompression and engine stop can all be remotely controlled.
o The use of rubber and vinyl hoses for ship interior piping not only facilitates piping work, but also eliminates brazing faults caused by vibration.
o Tandem type cooling water/bilge pump is available as an option.
8. Easy to operate
o Cooling water temperature switch and lubricating oil pressure switch are provided, and alarm lamps and buzzer are mounted on the instrument panel.
o Threaded hole in the V-pulley permits front power take-off.
o Manual starting handie permits manual starting.
o Positive clutch engagement and disengagement: propeller shaft does not rotate when clutch is placed in neutral position.
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
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.
Some break in hours on low/mid Revs would be very welcome and required to ensure longevity of this unit.
Additional brand new parts - propeller shaft, shaft holder, propeller, couplings, RC box,...etc - could be offered at extra budget costs according to requirement.
We work Globally, so we could ship to any destination via air, sea or road freight.
