Lately, I read about leaving water in the motor during winter will cause rust. However, I use my boat at least once a month during Dec. and Jan. so is winterizing for a month necessary in order to prevent rusting?
don't drain the water and watch it freeze and crack -- your choice...
winterization is only for peeps that put their boat up for several months at a time.. if you plan to use it once a month, more/less... just drain the water from each side of the block, manifolds/risers and hoses... no way it can crack then....
Thanks! I will add antifreeze if the temperature is going to drop enough to bust the block, but getting that cold here is unusual and I store the boat inside.
I make sure I change the oil before getting into winter, but I don't winterize as I might be able to get out on the water. Come spring she goes in in for a full check up, impeller etc. and no worries about rust, a rotting impeller or such.
Give a hoot don't pollute. Econ anti freeze or not I bet it will take more work to add this than it would to just drain it. Don't be lazy. Think about it how are you going to get the antifreeze all they way through out the motor?
I normally change my impeller at the start of every season and hook the water hose up in order to run the antifreeze out (and dilute it) before going to the lake. Even though polluting is a good point, I was more concerned about keeping the rust at a minimum. I think it's like Jay said. Keeping water in will inhibit rust. My thinking is it will also help lubricate the impeller.
