my wife and I recently purchased a 2018 F275 275. We love it but some of the systems are new to us. Questions: 1. What is the best coiled hose to use with fresh water wash down fittings. I purchased a Hosecoil product from West Marine but was just told it may not fit. 2. Is there any way to use my freshwater system to flush my Yamaha engines? Are there any accessories or fittings for this purpose?. I am on a mooring and have limited access to marina water supply.

Thanks for any thoughts you might have.
 
So I'm a n00b, I tend to go by Mr Idiot because I have lots to learn. But using raw, aka salt, water is not gonna work. Or are you on fresh water? Seems like too big of a boat to be on fresh but maybe Great Lakes? Whatever, if you are on salt water, that will not work to flush your engine, the whole point of flushing is to use fresh to flush out the salt.

My apologies if you knew all that, it's hard to know what people know and don't.
 
He said use his freshwater system to flush his engine.

I don't think the pressure will be high enough for an ideal flush but it would be better than nothing!
 
My raw is a standard garden hose fitting. If your is likewise, Home Depot will dial you right in with your choice of length in coiled garden hose. 8^) i put a pistol grip on it so that I can leave it on when I want to.
 
Two things on the raw water hose to keep in mind. Any coiled hose ( or not coiled) will do but if you get one a lot longer than you need, it can be a pain to store neatly.
The second and more important thing is to get a nozzle that says it is intended for salt water. Most if not all of the Home Depot options will rust (especially the spring) in a season or so. Personally, I buy the really cheap plastic models on sale sometimes at Walmart for a dollar and stock them. When they start to act up, I just install a new one.

Regarding the fresh water flush: Several posters on this forum has said they do it or were intending to do it. I am not convinced that it would work well but as said, it's probably better then nothing. That got me wondering if using that water in addition to something like Saltaway with the adapter cup might be better than just fresh water. How to judge if it works is a whole other story.
 
Joseph, congratulations on your new boat. I have thought about doing the same fresh water flush, due to low volume and pressure at my dock.

For my boat the “water math” does not work:
-Yamaha 300, the recommended flush time 15 minutes
-Freshwater tank size on my boat is 10 gallons
-Freshwater pump volume 4 Gallons Per Minute (GPM).

So for my situation, I’d run out of Freshwater from this 10 gallon tank every 2 minutes or so. As others have indicated the pressure provided by the pump, is likely not high enough as well.

In terms of the hose for keeping on the boat, I recently purchased the following and am happy with the compact size and the quality fittings:

 
brass nozzles work great.

There are some nice aftermarket flush kits but you may have a hard time providing enough water for 2 of them from your internal freshwater.
