I generally give it about 5 mins or until I can see the thermostats are working via the temp guage, so I know that the fresh water is reaching all the channels.
I only tend to use the flush port when on holiday and the boat is staying afloat in a marina.

I'm going to be controversioal here - as the impellor is a rubber item in a stainless lined plastic case, in ambient temps (I.e no heat to evaporate the ater & leave salty deposits) coupled with the fact that as soon as you turn it over any salt will be physivcally removed, do your really need to flush the pump?

I use muffs, but that's 'coz my museum doesn't have the block flush option!

IMV they wouldn't have designed the engine with a hose attachment if it didn't do the job properly. And furthermore, the impellor and housing are easily replaceable if they corrode. The engine jacket and waterways aren't.

Personally I'd replace the word 'properly' with 'well enough that it won't foul up too quickly and we won't get sued when some numpty gets his hand chopped off trying to put muffs on with the engine in gear'.

If the manufacturers were that concerned about corrosion,Suzuki wouldn't have made an entire range know as 'alka-seltzers' and we'd have teflon lined waterways by now.

Call me cynical, but what we get is what we pay for. It's not a bad thing-if we got the ultimate long life engines, we'd be paying far more for them than we do now.

Do they have a bit of a reputation for corrosion then?

Thanks for all the help guys....

I'm going to be really controversial...... I'm going to do both !!!

It gives me more time to stroke the engine whilst the Mrs puts the tea on

Flush until the tell tale is warm - that way you know the thermostat is open!

I just taste the water coming out of the tell-tale. When it is no longer salty... Job done!
