Nothing to adjust really, just have to make sure all the electrics are working correctly and the alternator is working properly. The engine won’t shift properly if battery voltage is low, and worse yet, it may jump out of gear and be damaged. Your shift switch could be intermittent also, the only way to confirm wiring/switch problems is to check for 12 volts on the forward lead at the knife connection while the engine is misbehaving.
Did the mechanic change the gear lube? If so, he probably used the wrong lube. Only the OMC "premium blend" lube can be used in this gearcase, regular gear lube might cause the engine to not shift or slip out of gear.
The electric shift gearcase is fairly robust, but there are a few NO NOs that can cause problems and damage. I’m thinking you should not use the engine anymore until a more experienced technician can look at it. Where are you located, perhaps a club member in your area could help you out or make a recommendation for a tech who is experienced with the electric shift gearcases.
