Optimax 250 Pro XS 2B360847 - Last summer, I chased a temperature issue the whole season. It was constantly struggling to get up to operating temperature. I went through four OEM thermostats to finally get it where it appeared to be working correctly. I just got my injection/fuel rails back from service, and got everything installed, including new impeller. Before going forward, I removed compressor strainer and back flushed the motor for a good 15 minutes. I then did an oil prime, and got it running on the muffs with good water pressure. Compressor temp was holding at 86 degrees. Watching both port and starboard temps using Diacom software, neither side would get up to proper operating temp. The highest one side got was 122 for a brief moment before dropping down to 116-118, and the other never got past 116-118. I ran it for a good 10 minutes plus, and it never got warm. I'm thinking if it was a thermostat issue, at least one side would warm up close to temp, but since neither side did, maybe I'm missing something? Honestly, I'm at a loss with this one. Any ideas??
