    I tried searching so I hope this isn't a repeat.

    I had my temp alarm going off on a boat I just purch. The great folks here helped me with an impeller change and the water flows through my engine great.

    Now I will be running for anywhere from 30 min to an hour just fine. We will stop and fish for a while and when we take off my alarm always goes off. Its the temp alarm. I felt the water coming out of the engine and it not hot. I think I have a sensor, or sending unit bad. Has anyone delt with this, and how do ya change it. I can sit and fish for 2 hrs and when I take off the alrm is on. It sounds like my boat is trying to hook up to the internet. It get pretty old pretty quick.

    It is a 94 mariner 40hp magnum.
