525 closed cooling question
 

this sould be an easy one, does anybody have the merc. part no. for the anti-freezed used in the 525??? Thanx BZ

Isn't it GM Dex-Cool? I use a bottle of Havoline GM Dex-Cool to top mine off with (it leaks some out in really cold weather). Otherwise you can see if you can find it a www.mercruiserparts.com.

I use Dex cool in mine.

Mercury's part number is #92-877770k1.

Where do you find Dex-Cool?

Autozone, Walmart, Advance, they all have dex-cool or equivilents.
