...for water to come out the pilot hole with ear muffs attached once the
engine has been started and is idling at about 700rpm?
Yesterday I was about to fog the engine. I put the muffs on, got a good
supply of water going, and cranked the engine. After a minute or so, and no
water from the pilot hole, I shut it down.
I called the dealer. He said to connect the hose at the flushing
attachment, but not to let the engine get over idle speed. Then, he said,
remove the rubber caps on what appears to be the intake manifold and spray
into them. This is much easier said than done, and is totally different
from what the book says.
Also, anyone have a picture of the 'intake silencer' or the 'fogging hole
of the silencer cover'. I'm thinking the spray should go into what appears
to be the air box through the wire mesh on the inner portion of the box.
Help?
If you did what the dealer told you, you now need a new water pump
impeller. The flush hose fitting is to be used with the engine OFF, as
it supplies no water down into the water pump, which is ruined in
seconds by runniing without water.
Some engines also require muffs that push water through BOTH sides.
Not all muffs do that.
With the proper muffs, set up correctly, there should be water from
the pilot hole almost instantly when you start the engine.
Different animal, but my Suzuki allows operation, not above idle,
through the flushing port.
I have had this happen on occasion because I had some insect
perpetually trying to build a nest in the pee hole. The engine was
getting cooling water, it just wasn't peeing. I can remove the plastic
plug that constitutes the pee hole and clean it out. I don't think you
have that luxury and I suspect the dealer is trying to get you to
essentially back flush a plug out.... at least I *hope* that is what
it was. I'd *never* run an engine over about 10-15 seconds without
seeing some water or knowing, in some way, that water was circulating.
Latest preferred practice (though I don't get it) is that one must use
muffs that push water through BOTH sides of the new Yamahas.
A dry water pump self destructs in seconds......
Thanks Gene. When I hook the hose to the garden hose adapter, water *does*
come out the pee hole. Maybe there was an obstruction and the garden hose
adapter setup allowed enough pressure to unjam it. I'll try the muffs again
today.
To fog the engine, I've got to get enough rpm for the intake to suck in the
fogging oil. An idle at 700rpm doesn't do it.

John,
The first year had my new engine, I paid the dealer to winterize it. I
watched them and made notes. It is very easy, but you still want to
do it yourself, Dave Brown has an easy to understand web page.
