I,d say we have 1.4 here in Essex and 4 bar in France but i bet you can put a fire out quick.Any reason for being so high.

If you all had a decent make of engine, such as a Yamaha you would not need muffs. There is a hose input that circulates water from the top to the bottom- its even a standard gardena type of connection..

It works ok but you must not start your engine with this system in use.
This injects the water into the cooling system above the impellor so thete is no water around the impellor and will burn out .

E-TEC too. Flush it running or not, per the Owner's Manual. Much more civilized and less worrisome than using the muffs.

I sort of dispute that statement (though I agree one should follow the manual, and not run the motor on the flush attachment.) Running off a powerhead-mounted flush inlet, the water runs backwards down the pumped water line, so it does, in fact, rinse out the impeller and housing. This can be verified by seeing how much water comes out of the intake screens. With the top mounted flush adaptor running the motor causes the impeller to try and pump the draining water back up, and that's where you run into problems (maybe.) I have heard of several people who routinely run the motor on the flush attachment, and have yet to hear of any horror stories (though I'm not going to be the first, either.)

Units with the lower unit flush adaptors (i.e. a threaded insert that goes into a plugged port on the leg, that you connect a hose to; a la Suzuki) may or may not be run, depending on the manufacturer. Suzuki says it's OK; Honda (as far as I know) says you can't.

Short version: Do what the manufacturer suggests in the owners manual, and you shouldn't have any problems.

No idea really - but that is what the water authority quoted in a report about something which was published a couple of years ago. I didn't believe it so put my tyre pressure gauge into the end of a hosepipe and it went off the scale instantly! I seem to recall it said that 4 bar was "normal" elsewhere.

Flushing engine

I was told by the mechanic at a dealer to run the engine untill its well warmed up as there is a thermostat that needs to open to let the water reach the whole system.

When i flush my suzuki there is a sudden change as the water from the prop hub begins to run hot . This time of year is easy to notice because of steam rising .

My water supply has 8 bar and it needs that full on to keep the tell tale running at full stream . Its probably more the amount of flow it needs rather than the pressure though .
