Engine flush

Hi,

As a newby to ribbing, I have a question... In the manuals and various things I have read it advises to flush out cooling system of the outboard ( a Yamaha 225HP in this case) with tap water, no problem I have done this with a hose and a clamp once the boat is on the trailer.... but I now plan to leave the boat moored in a harbour for at least a couple of weeks so do I still need to do this ? As getting the clamp on the water inlet port would be almost impossible to fix it on as with the engine lifted it is about a meter further back than the back of the boat so I would have to get in the water to fix it on, as I have never seen anyone doing this im guessing people don't bother or there is another trick that I am missing ?

Also I have been experimenting withe the trim of the engine, with the engine fully down the trim meter shows a bar at number 3, the graduation is from 1 to 5, with just a few seconds on the up button once the boat is planning it goes to number 5 ie max although, looking at the wake the engine still need to come up a bit, so I just have to look at the engine a gauge it which makes having a gauge a bit pointless, am I doing things wrong or do I need to recalibrate the gauge somehow ?

Any comments and tips much appreciated

Is there a top flush connection?

I know that more recent Yamaha's allow you to flush the cooling system from a top connection. Not sure if that's the case with larger engines?

Hi,

I have check my engine and definitely no top flush option, I managed to hang off the ladder half in the water and just about get the "earmuffs" on, I just thought there must be an easier way.
I suppose its not to bad as the water is 23 deg at the moment here, how long do people leave it flushing about 5 min I guess? And do you run the engine on tickover while doing this operation as without running no water was coming out of the outlet port?

do it when the engine's still warm. 5 min is plenty, engine must be running.

If on muffs yes, if using a flush point, no. My suzuki has a screw in one and the engine must not be running for this - so I was reliably told at last service.........

Advice I had with the new engine was to use the flush kit from the top, and not to run it with muffs from the main dealer.

Suzuki Manual recommmends running with muffs though.

I'm therefore confused as to best method, or does it make no difference?

A good set of muffs are just as good if you have good water pressure l prefer the bucket.
If your on a berth with a large boat you could flush with a flush bag tied around the leg fill with fresh water when down.

My Suzuki is used constantly in salt water and I am suspecting there is a build up inside the galleries as even with a new impeller the output on the wee vent is poor (it is not blocked). I have a big tank which I can put the leg in is there anything I can use to descale or clean in addition to just fresh water?
