I have not checked my water stainer for debris yet, but it seems like my engine water temp has been creeping up somewhat. On Tue it was running around 173 degrees. Isn't the normal engine temp on these H6 engines around 160-165?

Ours seems to run about 160-165. (2017 G23). If I am towing and full of ballast for a long time it will creep to 170, usually wake surfing but its usually around 160-165. This was yesterday. It was 100 degrees out all day (ultra warm water temps) and at the end of the session on the cruise back to the dock. -
Mine is 163-165 as well.I own and operate Silver Cove Marine, which is an inboard boat restoration, service, and sales facility located in Mooresville, North Carolina. We specializes in Nautiques and Correct Crafts, and also provide general service for Nautiques fifteen years old and older.

Does the H6 have a fresh water or raw water (closed vs. open) cooling system? My ZR4 with raw water cooling system operates at 163-165*. My ZR450 with fresh water cooling system would definitely creep up over 170* when the engine was pushed hard. If you push a fresh water cooled engine hard with lots of ballast you will eventually exceed the cooling capacity of the heat exchanger and the temp will start to creep up.2007 Malibu Wakesetter 23 LSV, 1995 Cobalt 200Comment

Its an open (Raw water) cooling system. H6DIComment

Even with closed cooling you should never see the temps creep real high. Eventually it goes to water which is a great place to dump heat.Originally posted by Evening Shade View PostComment

Thanks for the help. I will check water strainer first for issues/debris . If still high I may be back with questionsComment

Hi I would check the filter, make sure you do not loose the gasket. If it is still running warm, I would recommend checking out the impeller, it is always a good idea to keep a spare. Hope this helps.Comment

I would definitely keep an eye out on the impeller and strainer. I have had issues with the engine temp in warmer lakes. Mine runs 5 degrees hoter when the water in the lake is above 80 degrees, It can also be a thermostat issue. I would not worry unless I see 180 degrees.Comment
