solution. It features a parallel twin, overhead<br />
cam engine with multi-point fuel injection that<br />
includes a closed-loop, thermostat-controlled<br />
cooling system. It provides industry leading<br />
performance in a compact package combining<br />
remarkably low fuel consumption, very low<br />
emissions and an attractive <strong>hp</strong>/weight ratio. It<br />
is a complete “plug and play”, drop-in marine<br />
power plant providing <strong>70</strong><strong>hp</strong>.<br />
