How to flush a Yamaha 5hp?

[Zagato]

Firstly In the manual for this new engine it doesn't mention using a flushing attachment that you can supposedly screw into the leg (i have just been sold one, hope it fits this engine!). It just mentions lowering your engine into fresh water to flush.
Secondly if the flush attachment fits, do you just attach your hose and turn on for about 5 mins. Apparently you are meant to do it with the engine still warm... not possible on some slips without a hose. How about running through stuff to clear the salt easier? Thanks.

We use flushing Muffs attached to a hose and run the engine for a minute.

The dealer didn't recommend these. Perhaps they work better on a bigger engine!

I've always flushed by putting the engine into a large bin / drum and running it. If the water throws out of the bin .... take prop off ....

I tried muffs on my Honda 30. Couldn't get them to seal well (tried various methods) and ended up wrecking water pump. Also tried the screw in adaptor. Next time it will be a large 'bucket' with hose constantly filling it.

Back in Uk I've got a custom made deep, plasticised canvas bucket that i slip under the prop and extend up to cover the leg. Then just have a hose running into it at sufficient rate to keep it full. Can't run the prop in gear but flushes the engine well. Easy to empty and easy to store. Big solid buckets are sometimes difficult to get under the leg I find and even more difficult to remove when full. I keep meaning to make one for over here but never got round to it. On the list of jobs for winter now.

I used to use a wheelie bin with some plywood either side of the clamp. Needed holding onto but worked.

Or you could try this Outboard motor fresh water flush with a big enough fender.
