Re: Evinrude 9.9 throttle tension
Your motor has a cog gear arrangement from the tiller handle shaft to the intermediate shaft that transfers motion to the vertical shaft that is linked to the timing plate. There is also bevel gears from the intemediate shaft & again on the bottom of the vertical shaft. Something is loose in your linkage system.<br /><br />I would look at the nylon bushing in the tiller handle for one, another could be the armature bearing plate bearing #322435. If this is greasy, it may allow the timing plate to easily rotate. Also look at the flywheel/coil clearance. If the coils are set with not enough air gap, they may be dragging on the flywheel & the flywheel is rotating in the direction that, if this is the case the timing plate will be pulled by the flywheel into a slower position.<br /><br />After looking at your profile, if you are using this on your 27' boat, are you using a remote control? If so, then there should be a friction adjustment on the shift/throttle unit away from the motor.<br /><br />If you need further information as to how to tighten up the bevel gears on the control shaft, go to the article I wrote for PSA on 9.9 OMC repairs. This shimming would cover either a tiller operation, or remote usage, as the remote cable attaches to the bottom peg on the verticle shaft.<br /><br />Also this motor appears to not be designed to be placed in a fast position using the tiller twist grip throttle without holding onto the grip. I have no doubt that it will slow down under this situation.<br /><br /> The web address is
