The engine runs perfect, starts first go and water comes out of it normally, does it make any difference ?

I just bought my first boat and the engine is having some problems. My mechanic says the engine is “hunting” when you accelerate (I don’t know what hunting is). It’s not starving fuel either. The carbi was rebuilt and the thermostat was welded closed (it was open). We tested compression and the spark plugs and everything seemed fine. Any solutions? Engine is a PowerTec 40HP (knock off Yamaha engine) Thanks in advance
