I have a 2016 Tracker 190 with a 115 four stroke SN 2B216247, the engine is in the third hole and it has a 19p X7 propeller as this is the setup most used for this boat and motor. the steering is fine until I trim the engine up to get the rpm from 5000 rpm up to 6000 rpm and then the steering gets stiff. Others have this setup with no complaints. If this is posted in the wrong forum please delete. I have tried other forums and have not gotten much advice.
