![]() In February my local SeaRay dealer, Hirecraft Marine of Toronto, NSW, provided twin 6.2 Horizons in a 375 Sundancer sportscruiser. SmartCraft provides digital fuelflow, range-to-empty and fuel used since the last time the tank was topped-up. ![]() MPI provides turnkey starting just like a car engine and the system is compatible with the brilliant SmartCraft system which has more than 40 sensors to monitor engine operation and warn of any irregularities or even reduce engine revs should the need arise. However as with the carbie engines Mercury Marine recommend using 95 RON Premium Unleaded fuel. Unlike its 5.7 litre counterparts the 6.2 is available only with sequential multipoint fuel injection, which maintains more consistent running than carburetted engines due to the ignition timing advance and air/fuel ratio being constantly altered according to barometric pressure and ambient temperature. With the 6.2 Horizon the first service is at 20 hours or three months then every 100 hours or once a year, but I would do an oil/filter change every 50 hours or six months if the boat is being used infrequently. Running an automotive-base engine too cold not only increases engine wear but also internal corrosion due to condensation forming on the cylinder walls and greater blow-by gas past the piston rings which increases sump oil sludging between oil/filter changes. The engine-only dimensions of the sterndrive model are 814 x 740 x 559mm and it's available with a choice of Brave One, Two or Three legs, with the three-leg version weighing 486kg.Īlthough the Horizon version weighs only 23kg more than its raw/sea-water-cooled counterpart, it features thermostatically-controlled heat-exchanger cooling which allows the engine to operate at more consistent temperatures and emit fewer exhaust emissions because the engine is running within the temperature range for which it was originally designed. The sterndrive develops maximum power at 5000 revs and the inboard at 4800 with Wide Open Throttle revs ranges of 4800 to 52 to 5000 respectively.Ĭomplete with a hydraulically-actuated Velvet Drive gearbox the inboard version weighs 431kg and measures 1092mm long, 740mm wide and 559mm high, although the height is measured from the crankshaft centreline and not the bottom of the lube oil sump. In both the inboard and sterndrive versions the maximum power output has risen by 20hp to 320, although in the sterndrive version it's measured at the prop and not the crankshaft. This allows the 6.2 to fit into the same space as the 5.7 and although the weight is no greater the torque delivery and fuel efficiency relative to engine output are considerably better due to the longer stroke which improves combustion chamber 'squish'. At 101.6mm the cylinder bore remains unchanged but at 95.3mm the stroke is 6.9mm longer.
