    Default mercury 90 hp 2stroke gring when shifting to reverse 1993 mod.

    having a problem getting into reverse. it will go but you throttle up it starts grinding like its not going all the way in. was working fine til I started loading then it started this. shifts forward great. is there an adjusting spot on the cable? I haven't looked at it yet. I am mechanically inclined, but not on boats. thanks for any ideas. just got the boat used and don't have any manuals yet.

    Hi Pawpawdean and welcome.

    There will be an adjustment, possibly on the motor end of the cable but more likely inside the remote control unit. I don't know the actual control you have but, as you are mechanically inclined, grab a screw driver and have a go. Boats are pretty simple compared to cars etc., they are just usually more awkward to get at and if you drop something it goes "plink".

    Somewhere on the engine will be a lever that the shift cable moves. Detach the shift cable and move the lever into the reverse position. Adjust the cable until it fits nicely on the lever and your troubles should be over (until next time).

    Sounds like my old Mercury 90hp. If it has the to bolts holding the lower end prop shaft on it's the reverse gear. I replaced mine once with a used gear set, it lasted 2 years. Replaced it with a re-man lower unit. Problem solved. Best of luck with it.
