I use the hose connector port on the side of the motor,so easy.How is the 60 going on the 4.1,very fast I expect !

Thanks Giffo.

Do you ever use muffs?

Not used the 60HP yet.

If you dont warm up the motor does the thermostat heat up enough to get clean of salt? Im still using the flush muffs myself.

You should run it till it heats up I reckon also use both flush points

I can't seem to get my Yammie115 2str to heat the water.... I idle it, or fast idle it, for 15 mins or longer with muffs and it still hasn't got warm out of the tell tale. Should I maybe engage gear? That make a difference?

I don't use muffs on the 4 stroke,I use the external hose connector,but I flush as soon as I get home from the ramp so motor is still warm and thermostat may still open.I used to put the old 50 2 stroke in a tub of water as the old neighbour was a whinger about any noise over the volume of a fart.Now I do not have have any neighbours within cooee.

I hav found with mine that if i use the cheap muffs that have only have the water inlet come from one side that the engine will sound the over heat alarm. i bought a pair that the hose plugs on the front and has a Y section that supplys water to both sides of the muffs and all is good. Anyone else found this? I always run the motor on the muffs for about 15mins and only ever use the hose atachment if i come home late at night so as not to upset the neibours and run on the muffs asap in the morning as with out the muff flush the intake side of the cooling circuit dose not get flushed and the thermostat is shut as soon as cold tap water touches it giving a very poor flush.

15 minutes flush??? Hell you'll wear it out.

Whats the manual or the dealer say about the top flush port. Some motors don't like being run with only water from the top flush port as the waterpump runs dry?

[WalrusLike]

It doesn't take much to confuse me.....

I read that it can take 15 mins of flushing to get salt dissolved.... and that is with warm water. In my case I have never got the water warm yet. My drive home is a long one so motor is always cold.

I think I will try the bag idea.... The exhaust should warm the water in the bag maybe?

I would also be inclined to trickle in new water the whole time it runs.

I have the F115 and use both. My dealer told me that the top hose connector is fine the only thing better would be to use warm water????. So I now use the Muffs. I reckon it needs to get warm to get rid of salt. My telltale is cold too Walrus but that doesnt mean your engine is not warm just that your cooling system is good.

The Yamaha manual is a bit each way on the water hose but as i understand it there is no perfect option but best option is:

1: Best option Run it in a water bin/bag
2: Next best option is muffs
3: If you must with the water hose attachment with engine not running! ( maybe if travelling or dont want to wake the neighbours and do it properly next day)
