2003 mercury 25 hp/2 stroke: reverse

7110 16
I have had my mercury in the shop three times, repaired each, and the problem has reoccured.

my tiller will allow me to go into forward, neutral, but not reverse. apparently there is something going on with the linkage or something- but does anyone on here have any experience or similar problem?

the mechanic told me that the motor should only go into F/R when the prop is spinning. And after having it in the shop three times I am honestly starting to lose faith..

any input would be appreciated

HUh?

Take it to a different shop. The prop should not spin when its in neutral other than maybe a vibration roll, and you should be able to shift in either direction. Is this an all in 1 tiller or side shift?

Sounds like the mechanic knows the problem if it has been fixed 3 times, so either he isn't fixing it right, being cheap and not replacing a worn part, or there is an underlying cause that is causing what ever it is to keep having issues.

Time for a different shop, make sure its a certified shop!

I have same motor and mine does not want to shift if the engine is not running. If the engine is running then it is fine but when it is off I have to force it or turn the prop by hand to make it shift smooth. On these motors the shifter is built in the tiller and uses kind of flimsy pulleys with half gear teeth to shift off of the throttle pulley. I actually stripped my tiller handle trying to shift into reverse with the motor off.

yeah, its frustrating. will not engage into reverse even with prop spinning while off. while on, still nothing
The reason why its hard to shift when the motor isn't running is because the clutch dog isn't aligned when the engine is running the draft shaft is turning which means the pinon gear is spinning and the clutch dog aligns properly.

Same thing happens when you spin the prop only your spinning the prop shaft and reverse gear to align to the clutch dog.

When you say it won't go into reverse or nothing happens does the tiller handle shift? Or will it not allow you to shift? Call the guy that worked on it and asked what he did the last 3 times that will give me a starting point on telling you whats wrong with it.

thanks! man it is frustrating. especially when docking.. I always joke about how you can tell who's been running boats and who has never by how they dock.. now I come in to the dock at snail speed or on the trolling motor-not having reverse ;D

so i got my motor back today and my mechanic told me all he did was play around with the pulleys on the starboard side greasing them and and loosening the screws until things started moving freely.he said they were just binding up?
hope this helps??
hopefully i don't have the same issue as you
i will let ya know if it does it again

just got my boat back, apparently there was some washer way up on the shaft of the lower unit that was missing. mechanic fixed it up and it should be working fine again

the washer probably got lost during the lower unit service..worth a look
