No water coming from the telltale outlet!?!

[Adamn]

I have that feeling this has been mentioned many times before...
I have a 2007 60hp 4 stroke yam. I am getting it ready for winter and want to fog the engine. I placed a large dustbin under the prob which once filled with water covered the inlet ports up to the first cavitation plate.
I turned on the engine but no water could be seen even after 20 secs. I turned it off and attached the hose to the flush port at the top and water flowed out of all the ports and the telltale freely. The manual states that you should not run the engine this way. The last time it was out was 31st August and all worked well. Any advice?

blow down the outlet pipe with the engine off n try again. they get blocked easily. get blowing

My opinion is that the leg is not deep enough in the tub, my Yamaha Mariner will not pump water unless it is much deeper than the cavitation plate.

Try raising the bow to enable the engine to sit lower in the tub.

I have a feeling you may be right.... Because when I first turned on the engine I got a 2 second burst then nothing. 😕

Can take longer than 20 secs to fill the power head & start coming out of the teltale, I'd give it a minute. When you're on the hose, the water is under pressure & being forced into the leg. In the tub, the impeller has to prime itself, as already mentioned, if you can get the leg immersed until the water pump housing is below the water level, this will help. The pump housing is at the top of the gearbox, just below the split.

Thanks for the help. Deeper water and a little longer is what I will do.
