Hey everyone. Finally got the boat back out again (2004 280DA Twin 4.3's). Engines seems to be running too cool/cold. Lake temp = 82 degrees, Air temp = 90 degree's. Both engines running ~113 on digital smart gauge and same on analog gauges. Impellers replaced this season. I'm thinking T-Stat's stuck open. I think it's a 160 degree thermostat, but shouldn't it be running warmer than that? Better than overheating - LOL. But I'm wondering with the engines running that cool will the ecm/pcm sense the cooler temps and compensate with richer fuel mixture causing gas to be used at a greater rate. I'm not the original owner. For all I know the T-stats could be removed. Suggestions? I wouldn't think replacing the stat's would be to difficult. Thanks !
