I am very diligent about flushing my 320 sundancer with salt off after each use. I have quick connect snap in fittings for my hose so that's pretty quick. My problem has been getting the sea cocks closed and then reopened. They are waaaaay down there and even with the sea cock helper tool I just ordered still a challenge to the point I absolutely hate that part of each trip and makes it unenjoyable. Has anyone put an in line ball valve up in a more accessable place? If so should it be brass or bronze? also, any easier tips to the whole flushing routine would be appreciated if I am missing anything. enjoy the boat, hate my current routine! thank you for your insights
in line ball valve for flushing?

To me its a bit of a catch 22.
If you close off the seacock but don't supply enough water through the hose, you'll damage the impeller.
For me If I had seacocks, I'd keep them open. (I have a B3 with no way to block off the water inlet anyway)
Keeping it open will allow a small amount of salt water to be drawn in IF you don't have an adequate water supply
OR
If the supply is excessive, it simply pushes back out through the thru hull.

Thanks, I have plenty of fresh water supply and mercruiser told me the quick connect is designed to allow the correct amount of water so leaving the sea cock open would defeat the purpose. I'm looking for an easier way to close off the sea cock and some tricks from the people that have done it longer than I have to make it much easier.
Side track... take a look into Volvo's Neutra-Salt system. Neutra-Salt (and other similar things), work well even in conjunction with salt water. You pretty much just push a button - that's it.

It's going to be a very very small amount of salt water. @mnm99 did an analysis when he installed his flushing system that he did a write up on.
A side note as a reminder to anyone flushing, just make sure you turn off the shore water supply within 15 seconds of shutting down the engines or you risk damaging your engines.

I think you missed my point. Essentially there is no benefit to closing the seacock. If you have more than adequate fresh water supply, the excess gets pushed out of the strainer.

Sorry if it wasn't clear, my last post (#7) wasn't directed at you Kevin. It was a response to the OP's reply in post #3.I was trying to reinforce your statement, not contradict it

I agree with you, as we are both saying the same thing.
