My 2007 210 Dante overheated while idling but ok at cursing speed. What is it. Thanks in at advance for any help

Unfortunately, I have a lot of experience pin pointing overheating issues on a 2007 year boat. If your overheating at idle but not at cruise I would check for air leaks. More than likely around your strainer.

It also could not hurt to check your impeller. If your boat is closed cooling check the raw water side for debris in the exchanger. Once you have checked all of these areas, you should be good to go!

Good luck!

Check the strainer. Then check the impeller. A damaged impeller won't suck at idle , but the pressure caused by the scupper moving through the water will usually force enough to cool the engine. Those would be my 1st two places. My guess is the impeller

If you do find it shredded check all the lines for debris

Drain the sea strainer, attach, start the boat, count 1 one thousand, 2 one thousand, 3 up to 5. If it's filled by 5 impeller good, if not change.

or just take off the two screws on the impeller cover - when they are bad its pretty easy to tell, it will be cracking and missing arms.

Thanks everybody, I'm going to check the impeller next. I got through the high school age club volleyball party by not idling and moving fast. You guys are great
