2002 90HP Overheating at low RPM

[walleye1]

I have found in the past most yamaha's will over heat if the exaust ports arn't covered with water.

I don't think water should be coming out of there while running. Wasn't there another OP recently with this observation? There may be a problem where the tube connects to the pump. The rubber grommet/seal. Now that I look again, seems to be more 2 stroke oil than what might be "normal" in the first pic.

Yep, wasn't long ago, exact same thing.

Turned out the seal was missing (I believe) at the top of the water tube (as I re-call, closer to the powerhead)..

What do the two stroke guys think about the oil? Different issue?

Well, that small drip must be coming from the power head lower cowl...

Sounds like a small oil leak somewhere finally made it south...

Yes a guy a while ago had same problem...missing seal on water pipe. I wonder if that little damper seal is also missing, allowing exhaust to come around the water pump and getting mixed in with all the leaking water that is supposed to be going up the pipe to the engine???

Thanks Scott...I do not know what I am doing wrong wit the pictures...will figure that out later.

I wanted to tell the OP to look at items #1,2,3,4,14, 15 11 and 10. Make sure all are there.

No problem...

I simply go to the parts site, "snip" the pic.

Then upload to Postimage, (size 19" screen). Copy and paste "the link for forums"

go hunt another wabbit or chase a different ghostie. water coming out at that point in the pic is normal.
do make sure that all the water tube seals are in place and the housing has ZERO melt damage.

Who the hell knows? Lower unit still on the last I read.

Thanks, folks, yes I have not pulled the lower unit. I am waiting on the housing - impeller parts to arrive. I did spill some oil when refilling more than once so the oil could be that issue. Good to know that water out of that point is normal.

Pic size is based on the size of ones hands. Or member. Here's mine.

Boscoe if your member is that large how do you walk around?
