    Verado 225 temp cycling up and down. Need advice!

    Hoping to take advantage of the expertise here even though I no longer have a high perf boat. Found lots of posts about this problem but no solutions. Have twin 2015 225 verados. The port engine temp slowly rises up to 170 and then rapidly drops down to 140 and cycles back and forth. The stbd stays steady at 140-145. It’s possible this issue started after running through some shallow water. I changed out the thermostat and no change. I did find a small pebble in there though. Water pressure is even across engines. At one point I thought the issue resolved when running full throttle and then letting off. That’s no longer the case though. Was thinking poppet stuck closed because of that solution? Not sure if that would make sense with the cycling back and forth. Any advice would be very much appreciated! Thanks
