Scuba or anybody else
I have a 2012 Honda 90 outboard on my boat and I noticed that I had no water from the tell tell running at trolling speed this weekend. I kept it at that speed under 1000 rpm back to the dock and never got a warning or anything. We kept checking the oil filter and it never got hot just warm ( you could hold your hand on it). I think it just may be clogged tell tell port.
My question is at 1000 rpm would it over heat? What should I do to trouble shoot this ? It took us almost an hour and a half to get back to the dock at that speed, thoughts?
Thanks

well I am not scuba but this is what I would do
does that have the hose hook up to flush? my dads yamaha does , mine is too old
hook up a hose you got nothing to loose make sure you can get water out the Pissah
make sure the port isn't clogged
if you start up with muffs on or the motor in a barrel of water and you don't have water from the Pissah in a minute shut down keep looking for the blockage
would be a little hard to think the impeller would be shot on a 2012 but it is possible , try removing the hose from the port where it goes through the cowl and see if it come out then
once you have it figured out why your getting no stream of water
toss the compression tester on each cylinder , if you did damage that would be how you would see it with out taking anything apart
I had to speak Nessy for Pissah instead of how we say in WI with an er or the filter blocks it

America only has one issue, we have a Responsibility crisis and everything else stems from it.

If it over heated it would get as hot as a car engine correct? That oil should be burnt and the filter untouchable correct?
Thanks I been looking at youtube to find trouble shooting tips too
That's why I called it a tell tell LOL

I would bet it’s the impeller in the pump. With age they do crack And can come apart.

I love the smell of burning spruce---I love the sound of a spring time goose---I love the feel of 40 below---from my trapline I will never go!

Yes. The impeller on my 99 Yamaha came off the shaft. The shaft was still spinning but the impeller wasn't. Engine got hot in a hurry.
Most in this country have things people in other countries only dream about. Yet, they want America to be more like those other countries.

I saw no signs of it getting hot and it run for almost 5 hours that day . Oil clean unburnt, oil filter warm not hot, no warnings or power issues. Wanting to make sure I did no damage and get it working properly so I can sell it.

Nope muffs won't work in that case as the water pressure from the hose is enough to cool the engine with no working impeller.

But if the line is clogged I'd know correct or if I cleared it?

The muffs would be a good way to clean out the system. Then go to the barrel to see if it pees.

I'd pull the lower unit and take a look. Probably a bad impeller. I bought a motor that had the impeller fall apart and I had to get chunks of plastic out of tube from the pump housing up to the power head. It will take 20 minutes to pull the lower and take a look. 2 hours later you'll be fine.
I only put 40 or 50 hours on my outboard each year and I change my impeller every 2 years. They look brand new when I pull the old one out but I want to see the condition for myself at least every other year. I don't want to be 10 miles from the ramp and not be able to get back. If my truck breaks down I can walk for help. If my outboard dies I can't walk very far. Had that happen once. Watched the ramp get further and further away while we drifted down the river.

You will get more pressure from muffs but you may not get enough volume. I had an old Johnson that would not pick up any water from a barrel but muffs "pushing" the water directly into the ports was enough for the impeller to work correctly.
