Re: function of the quadrant?
Do you need to be at idle to go from nuetral to reverse or fwd?<br />You must be near idle. There's a throttle position lockout for above about 1/3 throttle for neutral. Have a look on the starboard side of the engine above the shift lever. The big brass bar interferes with the magneto plate.<br /><br />
Can you go wide open in fwd only?<br />Yes, the neutral lockout also limits reverse to about 1/3rd throttle. If you ever saw the reverse thrust bearing compared to the forward, you would understand why.
<br /><br />
Must be in nuetral to start?<br /><br />No. But the engine won't crank if the throttle is set much past 'Start' due to the safety switch on the port side crammed between the block and armature plate.<br /><br />
Evinrude quadrant I'm not sure what you mean by this? Could you explain please?<br />EDIT: I think you're talking about the big brass bar (Shift lockout). If so, quadrant is a much better name.
<br /><br />If you were only getting 1/2 rpms, suspect ignition problems. Loosing one half the ignition can be caused by a variety of things. When the magneto is healthy, it'll throw 3/8" long sparks off both cylinders.<br /><br />PS - I'm presuming this is a mechanical shift 40hp. If yours is the selectric shift with the pushbuttons, please indicate. Thanks!
