Bf150 2018 overheating block temp

[Gbell]

I read all the forums but basically the conclusion is poor maintenance and flushing. because after a new head that was eaten through and a barnacle busters flush for an hour, new thermostats, pressure valve, full water pump kit. The block temperature sensor 1 keeps creeping up over 100° C in 40 degree water above 5500 rpm’s. Warmer water will set the overheat alarm.
