2000 Tahoe Q3 with 3.0 litre engine. I have religously winterized this engine until last year. (circumstances led to me just draining the block and heads with the new mercury drain system). I started the boat up and had no issues this summer.Other than it ran a little rough until i put some seafoam in the gas tank and used up old gas. I am thinking of just doing the same thing this season. Any thoughts? Last year was quite cold too...I am in New England |

The benefit to filling the cooling system w/ anti-freeze is that you minimize the corrosion opportunities by displacing most of the oxygen (in the air) in contact with the bare metal. |

The pink stuf is not very anti-corrosive. There is a blue colored marine engine antifreeze that reduces corrosion. |

Also put some Stabil and Seafoam in your tank before winterization and make sure your tank is full to reduce room for water to condense inside the tank. |

Ayuh,.... While I don't trust those draining Systems....
A Dry block is a Safe block,.... Air don't Freeze...
In freshwater,... Cast iron never gets past the Patina stage.... |
