When I got this motor it didn't run, thanks to many on hear my family has been enjoying this rig. I replaced the water pump when I initially got the motor, based on the temp guage at idle speed (no wake) it would creep up to just about the 175 (80 celsius) on the gauge and then drop down to 140-150 up on plane. Last water pump change (18 months ago, less 100hrs) I also did the thermostats. Now at idle it looks like its creeping up just above the 175 (80 celsius) on the gauge but still drops back to 150 (maybe a tad higher). I looked in the shop manual and I don't see anywhere what you should expect as normal operating temp. Would carbon build up contribute?
So planning to do the water pump right away, but was also contemplating doing a vinegar flush. What should I expect for normal operating temp & any feedback on vinegar flush?
Thanks.
