Well I am trading my 99 205V in on a new Malibu in a few days. I went out to the lake to take one last spin before I got rid of her. Well de winterized the boat and started great blah blah.
Well I was going down the lake and I noticed the temp was at about 200 (usually 160). I backed off shuter her down to check the engine. Felt the block and the temp was not abnormal to the touch. The manifolds were warm (normal temp)I could keep my hands on them for a long time without burn ring. So all inspections check out.
Fire the boat up and the temp read 180ish. Idle down the lake and the Temp goes to 160 then back to 220. Just a constant dance back and forth. The impeller housing was completely cool also. So I just idled back to the ramp put it up. Also if I raised the RPM the temp stayed more on the higher end. I have always found that temp will go down 5 degrees when the RPMs are higher (because there is more cool water running through.
OK please feel free to ask any questions but anyone have any suggestions?
Thanks
Preston
