i have a cheap looking (probably isnt cheap just looks it) plastic single gear/throttle lever thing on my boat.. i think its a morse make same as the steering..<br /><br />it has a pair of buttons on the top which take take the drive all the way up or all the way down.. trailering...<br /><br />another pair of button on the top which take the drive part way up or part way down.. trimming..<br /><br />the lever itself pulls outwards to disengage the gears from the throttle.. starting and such..<br /><br />but there is another trigger type button on the underside of the top of the handle.. this one dosnt seem to do anything.. is it just redundant in my case or should it do something.. i cant think what.. but i have wondered.. ???<br /><br />it might be an alternative method of disengaging the throttle from the gears and isnt used on my boat.. praps u should have to press it before u can move the lever out of nuetral.. and its broke.. dunno.. only guessing..<br /><br />just curious..<br /><br />trog100
