Motor Not Peeing Well Initially

[TSCTSC]

Noticed that when I started the motor last outing, the pee stream was not very strong for about 5-10 seconds. And then after that, when I increased the RPM and starting moving, it was better. I had the impeller changed last fall. I had not noticed this before and am not sure if this is normal or not. Please help. Thanks.

There may be some dirt in your water pump.

Try putting one of those motor flushung muffs on it and flushing it out.

I have also cleaned the dirt out on older motors with an air compresser with a rubber tipped blow nozzel.

If the stream does not increase you may have another bad impeller.??

If it was my motor and there was only a few seconds of decreased flow I would not be to worried. If the flow stops you are in trouble!

If you have ever run the motor while it was out of the water you may have damaged the new impeller. It sometimes only takes a few seconds!

Was it ever started dry even for a few seconds?

Did you put a little Vasoline on it when you first installed it?

If there was any old burnt rubber inside the housing that wasnt 100% cleaned out when the new one was installed it might have ruined the new one already too.

Excess dirt,sand, mud as mentioned before too.

What about ice??? Could there be some ice in the system that made the pee poor initially, and then got better as it cleared?? If so, I should not have this problem when the weather is warmer, right?

I have had the port where the water comes out of the engine. Take a small wire and insert in the hole where water comes out, while you have the water muffs on. If any blockage, it will be unloadged then. caj

Not having a stream for 5-10 seconds isn't unusual. On the other hand having a weak stream isn't good. Once the thermostat opens up you should have a good stream while idling. Like Cliff stated there could be debris somewhere. EOTL asked, did you run the outboard out of water. I've seen guys start their outboard out of water just to hear it start I guess. Its hard on the impeller and a bad idea.

[TSCTSC]

No...I never run or even try to start it out of the water. I know that it is bad. The stream is poor at start but is good after that. So....

[Surface Tension]

If it has a good stream then I wouldn't worry about it.

I would guess that what is happening is that the delay is due to getting all the air out of the cooling passages, which would result in a lighter stream. As Surface Tension said, if it's only for a little bit after start up and it's just fine after that I don't think you have anything to worry about...

I had a 30 HP that did that as well. I took a piece of wire and poked it in the pee hole. Cleaned it right up. Just a little Muck in the outgoing port. Not saying this is your problem, but it is a quick and easy possible fix.
