So connecting a (running) hose to the engine while it's off will flush through sufficiently then Ian? Or did I misunderstand? Never had to flush the engines before so it's all new!
Yep on Yams and probably others there is a small dark grey hose with a connector on the side of engine outside the case. Unscrew with fingures and connect one of these Accessory Adaptor: 2289 - Hozelock
to the hose section ( not the engine block- that is just a blank holder) , then attach the hose with Hose end connector (12.5mm & 15mm): 2166 - Hozelock
and wash through. DO NOT run engine if using this system- not needed and will damage it. The water will wash through all sections and even come out of the tell tale so as this coools and is no longer salty, you should be done.
I connect almost everytime and run cold wash as I cover boat so ten mins I guess.
If you use engine muffs near the prop then you need to run engine but hose above is good and ample for looking after it.
You will be amazed how many dealers dont know where that flush is!!! I have attached an image to show what it looks like. Turn the nurled plastic cap and then connect to that not the base it is on block with. May be left or right and side but same idea depending on engine size
Can even be done afloat if on a pontoon . lift engine and attach same way
