Flushin the engines

[Dave Rintel]

sorry if this has been asked before but something occurred to me at the lake today. I run the boat in the lake all morning and then once it's out of the water I flush the engines. Then I realize that the water I'm flushing with is the same water in the lake and that it circulates through the engine the same way. Since my boat is on a lift in deep water I'm not sucking in dirt I might be if driving up to a trailer. So what is the advantage of flushing?

Not much point in flushing engines when boating in fresh water....unless you think you might have sucked up sand/mud etc.

I only flush after salt water usage. Most of my boating is on the third cleanest lake in the country so, like you, I see no point in flushing.

I don't flush in fresh water...the only thing I do at the end of our day is blow out the water and done.

Flushing in fresh water is good if you boat in a silty water or in a high mineral content. Minerals and silt can clog cooling passages very easily.

I flush with salt away even in fresh water for mineral build up. Worth the 3 bucks to flush it with salt away.
