New to me XR6. Allegedly serviced in 6/24. Hooked to hose and couldn't get it to peeing until i went back and pressed the "ears" against intake. Once i did that it would pee at idle. Wouldn't if i didn't hold ears. Increase rpm's and it would pick up. I shut it off thinking I just need to put in water. Launch and crank, still no pee at idle. Increase rpm, kick into gear and I get a stream. Increase rpm and stream increases. Factory gauge read from 5-15psi. Is that normal? If not, first thing to look at be replacing impeller? I've had a lot of boats...never had one that was slow to pick up water. Had a couple that wouldn't pick up any water...but never one that was slow.

Do you know when the impeller was last changed? I bet it's due. Looking online it appears those motors run in that range, and it concerns a lot of owners. Do some research but if the impeller was in fact changed recently I bet it's fine.
i believe those have a thermostat that doesnt kick in until up to temp. did you give it a few minutes at idle?
Could be some alge growth in the line. I had that issue on a different brand motor. It was right inside the intake. A pressure washer fixed the problem.
I would change the impeller.........which already should have been done when it was serviced.
I don't know about that model but the pisser is there for a reason. If you only get flow when revved up something is wrong.
Could be as simple as mud dauber nest in the pee pipe. (my 50 hp merc has this problem so I make a "flap" out of a piece of painters tape to keep them out).
Could be as serious as a blocked cooling port in the engine which will result in engine failure.
Try wiggling a piece of 14 ga copper wire in the pee pipe with the muffs on and see if anything comes out and restores flow.
IF that doesn't fix it, I would look at having the motor serviced and the waterpump rebuilt.
