engine temp question

[gwhjr98]

350 V8 - 2004 - Normally, it runs right at 175-180 degrees.. but I noticed it was drifting higherup to almost 200. Its hard to tell where it is on the gauge but it was almost to 200.... so I changed the impeller. It seemed to help but it still is running at least 185 or 190. I can see it drop a little when I am in Idle. Is this something where changing the thermostat would help or is it something else? I assume its 160 degree thermostat.
thanks

Check and back flush the oil cooler. Stuff usually clogs there and restricts the flow up to the engine.

Also check the elbows and manifolds. At 8 years old they are probably in need of looking at... Are you in salt or fresh water? do you have dry-joint elbows or the old wet-joint?

Re: engine temp question

The boat is in fresh water. not sure what you mean by dry vs wet joint elbows but I will look online to see and check the boat. Is it also worth changing the thermostat?

UPDATE: I changed the Thermostat and it resolved the problem. Thanks
