Mercury Fresh water Flush

ashbypower · 24 September 2006, 17:03

Does anyone know where I can obtain the hose connector to fit the Freshware Flush system as fitted to Optimax Engines?

Looked on the net and failed miserably

Thanks in advance.

Your local Mercury dealer will sell you one.
If its a V6 you need part number 22-852400

Or 75/90/115 opti they do a thing called a coastal flushing kit. Not sure whats in it but its part number is....858566A02

Many Thanks TD,
I don't need the whole Kit, the '90 is fitted with all the hardware except the piece that connects to the hose.

Regards

I searched the internet for UK suppliers last year and ended up buying one from the states !
If you specify USPS rather than UPS or Fedex the shipping costs aren't too bad. >>>> and it does make flushing a doddle

Think I bought from West Marine ... but these are the same.

Ok, in that case you just need part number 22-857175 Which is called a coupling insert. Its the male end that goes into the female end which im guessing you already have on your engine. If its a newer engine then you will have it tucked in the cowl tray.

Great TD thats exactly the part. We have a '05 Opti 90and as you say the female connector is under the cowl

Tnx again

That looks very much like the attachment that is screwed into our garden sprinkler. I bet you will find that attachment in any decent garden center for a lot loss then Mercury will charge you.

Edit: here we are; close enough: http://www.diy2u.net/products/tool-a...HOSECON04.html Put a *tiny* bit of silicone around the thread and screw it in

I think the adaptor has a non return valve in it - and it is a much finer thread. You leave the nipple fitted to the engine all the time.

Just use normal muffs - I heard it said that the freshwater flushing kit doesn't get the impellor wet and may damage it although I would have thought Mercury would have thought of that?

When flushing with this type of attachment do not run the engine as the water pump impellor is bypassed and will burn out.

Tried one of them one my 225 opti, its not long enought for the connector to fit and lock on

Jeff, what size is you engine that you fitted this one ?? http://www.boatersworld.com/product/367900057.htm
would seam to be long enough ??

I have a 150 opti and it works fine. The merc manual does say its ok to use the flushing port- even with the engine on tick over.
They are made by TH Marine ... and West Marine do them as well at $16.99. Different types for OMC and Merc engines

Not quite true, you can run them with the flushing adaptor, thats what its there for. Just dont rev it, its just for tick over, (same as muffs).

Instructions for yamaha outboards is not to run engine when using flushing adaptor.

Flush out the engine cooling system with out running engine.. IE water mains pressure replaces water pressure / flow from pump.

Flush out at home with out engine noise or fume pollution... Keep odd ball next door off your back.

standard hose fits in like a glove, no leaking, no need for adaptor... just unscrew the plug and put the hose in!

............. but don't loose the plug

Thanks to all for your replies, getting sorted from RIBS. For info, Hose connector doesn’t fit

Whilst ashore we use muffs however to flush the system whilst afloat this fits the bill.

Tnx

It's purpose is to enable you to flush the motor without running it, such as when you have a pontoon berth.
