Enjoy the boat!!

I have a 2003 and now i will change mine too. I heard there were issues with that antifreeze.

The only issue with DexCool is that if there is a leak somewhere and it's exposed to a lot of oxygen, it tends to harden and clog the tiny orifices in a road car/truck radiator.

The orifices in the 496 heat exchanger are way huge in comparison and therefore would not cause a problem. Although, a leak anywhere on anything is not good.

It does have a five year recommendation.
