I didnt have any issues with engine tempand etc. But I get a 2 beep alarm every minute or so. I bought the techmate pro plugged it in and received a 36 fault code sea water high block pressure. I replaced the impellars in alpha 1 gen 2 thinking this was the issue. Both impellars were fine but changed them anyway. I think its the sea water pressure sensor and I think its located on the back of engines on the left side. I am not sure tho hence why I am writing this post. Can someone provide me with a picture of location or an explanation. Help would be greatly appreciated.
 
I think it' located on the steerng water cooler or the water pump housing. Easy fix. Just did mine. Was stuck at 43lbs with engine on or off.
