2015 mercruiser 4.3mpi. When turn boat sharp either way it throws it in limp mode with constant alarm. It will reset when I return to idle goong straight no issue. 410 hrs never had any issues. At begin of season I replaced carrier seal and water pump rebuilt in lower outdrive. Gear oil reservoir sensor is ok and fuel separator fuel replaced. Any ideas?? Sounds like a fluid sensor of some type. Oil pressure and water temp on gauge are ok. A little help greatly appreciated.

Need to check diagnostic for fault codes. Otherwise it's just a guess and the parts cannon is lacking ammo rn

Welcome
Scanning for codes is best, possible oil or water pressure switch's are the ones that come to mind first

Have you checked oil level?

Oil level ok. I d/c oil pressure switch and started and hard alarm came on right away. I have it a shop now to get scanned but it’s a waiting game I guess
