Yam 90 Sticking in gear sometimes

SimonCh · 07 March 2013, 08:25

Alright folks,

My yamaha 90 2 stroke sticks in gear sometimes for a few seconds after i shift in to neutral. It has always done it, and although I am used to it now and always come slightly past neutral to get it out of gear, Its not a massive issue but I shouldnt have to do this. When i did my impellor change I think i may have got the gear selector shaft a spline out - is this possible?

Cheers

It is.... but you'd notice something very wrong trying to get into reverse.

It sounds more like your cable adjustment is out.

Yep stretch or wear in the cable

I had the same problem, then it went very stuff - and it was fixed by new cables

Before spending money or dropping gearbox, check the following.
1) 703 Control box has a white plastic cam for the Red neutral lever to locate in. This is a favourite for coming loose and being intermittently sticky. Tightens up with two screws once handle is removed.
2) under and slightly forward of the bottom carb is a large but with a spring inside it and a ball bearing on the gear linkage. The spring is mild steel and rusts. Remove bottom carb and grease/replace spring (I have some). This produces permanent stiffness though and can be tested by hand if you in clip the control cable & work the linkage manually.

Should be a nice easy job on your yam Simon, unlike Steve's Evinrude. Got to love the yanks and their dedication to the imperial system... :P

When you go from ahead to astern how much does the engine move on the top engine mounts? My guess is the gear shift rod is fouling in the middle of the steering swivel tube.

Other thing to check is idle speed. If it is too high then it may be difficult for the box to disengage with the extra load on it. Should be around 750 ish in forward gear.
