I do the taste test, I leave the engine running while I wash the boat with soapy water, I use that wax stuff for cars, then when I need the hose pipe I stop the engine and rinse off. Normally about 10 mins.

My brother stacks his rib but still uses earphones to run the engine with it still in the water - better than nothing, I have heard of people running their engine in sail bags full of freshwater whilst still in the drink, although obviously not in gear!!!

Flushing is good, but do not fear guys, If you should forget to flush one day, your O/B wont dissolve overnight.

O/Bs and outdrives live on moorings and in marinas for months with little adverse effect when regularly used.

Apart from last week when she was moored all week in the Tamar while in Cornwall for the week, we always flush the engine for 10 mins with the muffs, either at the slip if there is a tap or as soon as we get home.

Engine Flush

I flush mine after every use with muffs

I run for about 5 mins then disconnect the fuel and allow to
run out of fuel and stop. is this OK?

Cheers

Paul

Yeah, same as I do. It usually takes mine 5 minutes to run out of fuel (I disconnect it at the tank end) plus 5 mins flushing

Is starving an engine of fuel a good thing?

I really don't know with marine engines, but with some of the cars I've owned, it's not a good thing. I would add that I'm not a technical soul!

Not on some injected cars and trucks (some diesels are especially bad for this): running the fuel system dry means repriming the system, which as I recall, is not that easy to do.

I haven't heard of this on boats, though, and I know that my injected F115 will refire quickly after being run out of gas (but don't ask how or where...)

If you only flush once in a while its better than not at all. Look after your engine and it will look after you.
As you say its when the crystals form that there can be problems - I've been told by those that are supposed to know, that its only necessary if the motor is not to be used within a week of last use. If its used regularly only really necessary at the end of the season.

I do however rinse mine thro' the flushing port after almost every use - sometimes I don't if I'm know I'm using the motor the next day.
