Engine Temp??

[Canaltrash]

I own a 2001 Bayliner Capri 185 with a 2001 Mercruiser 3.0<br /><br />I recently replaced the lower unit water pump and the Thermostat. I still think I am running a bit warm.. the Temp range says about 175 when idling and about 185 to 195 when runnin it..<br /><br />I am not a mechanic.. but sure would like to know if I am still running at a too high of a temp. <br /><br />Do any of you mechanics know what temp I should be running???

Re: Engine Temp??

Is this raw water cooled or fresh water cooled?

I am not sure of the difference?? I do know that I do not have a heat Exchanger.

Re: Engine Temp??

Then you have raw water cooling.....What temp. stat.did you putin? 185 is warm,not enough to harm your engine, but warm. I would think around 160 would be better. Engine is 2001? It is probably time to take the risers off & see if they have scale build-up at the water outlets.

Clean...or replace.... If they are factory mercruiser, they should still have life in them.........Rod them out....J
