250 SHO Low Oil Pressure at Idle

[John__S]

I have 2013 250 SHO with 280 hours. Prior to yesterday, my oil pressure at idle is between 15 and 20 psi. Yesterday after the final run it was 3 psi. At higher rpms the oil pressure appears to normal. I did check the oil pressure when the engine was cold and still 3 psi. Oil level was normal. The last couple of weeks the engine temp has been 145 which is higher than the norm of 142. I also checked the crankshaft end play with a dial indicator and it was showing .022 of an inch which in my mind is way too much. I might have a thrust bearing that is failing. Any thoughts? My motor has Yamaha warranty until Oct 2020.
