My fishing partner has some kind of problem with his 94 135 Merc. When he come up tp plane the lower unit bumps abouit 2 maybe 4 times and then it stops and runs great. Same thing happens every time. In reading some of the forum posts regarding simular problems I'm thinking it may be in his control box. Some have mentioned in this forum that over time the cable be somehow out of sync and the forward gear is either engaging to late or to early however that goes. He has a Cerner Repair but it is worthless.

How difficult is it to inspect and I'm not sure we would know what we would look for if we opened the box? Having some kind of an ideal what we're looking for would go a long ways towards fixing the problem.

Sure could use some help on this one.

It's either shift adjustment or the clutch dog is going bad.
