Reverse went out on 90hp tiller

[10,000 Casts]

1996 90 HP Mercury tiller 3 cylinder. Went out with a month to go in last season but forward works great. I adjusted the linkage inside the motor cover earlier today and it helped at first but within 5 mins it would go click click click but it would still engage. Then it wouldn't engage at all. There wasn't any metal shavings in the lower unit and forward still works great.

Could it be the clutch? The spring? The linkage? Any ideas on where I should start?

Thanks!

If you can't adjust it out with the adjustment set screws on the upper side of the linkage anymore, than you are likely due for a new clutchdog. Depending on the construction of the gearcase on your motor, this can be a pretty simple do-it-yourself job.

Some gearcases split in half and make this job easy. Others require all the parts to be put in and taken out from the prop-shaft hole (much more difficult).
