1998 honda 90hp no tell tale new impeller

[jstme123]

I have a 1998 honda 90hp bf90 barely drizzles watter out of the tell tale at idle does pick up a little at throttle but not alot. New impeller was installed, tell tale tube is free of debris as well. Not overheating but i cant figure out where the water is going.

Did you check the tell tale at the engine block, where the hose starts, or just the outlet/first couple inches?

I pushed weed eater string in about 6” or so then popped the hose off and can blow through it freely.

So you can blow through the hose OK, but what about the port the hose plugs in to? That should pass a couple of inches of weed eater string easily.

It makes a hard turn and i did not try to force it. But yes i can easily blow through the line.

I had a very similar issue on my 50HP Honda and think it might be resolved, maybe the same approach will help you too. See the thread here:

I blew water from the thermostat housing down, from the water pump tube up, in through the pee line and blew air through the pee line too. It made a mess, but seems to have gotten a lot of junk out.
