Engine runs perfect, no alarms, overheating etc even when letting sit idle for 20 minutes with muffs on.. but there is no water coming from pee hole other then a tiny dribble, tried running weed eater line up in hole but nothing has helped, engine stays cool to the touch everywhere some I'm assuming water is circulating thru cooling jacket just not coming out pee hole..
How far should weed eater line be able to Go up into hole, it only goes in a couple inches and hits something hard, when I look up in it with light all I can see is something grainy looking like a stone or maybe the end of a piece of tubing.

On my 50 hp Merc 2 stroke I could remove engine cover and get to pee hole hose and unclogged with small wire cant do it with this one.
Want to take in get impellor replaced(previous owner said it was replaced a year ago) but only 2 shops around are backed up anywhere from 3-6 weeks or more.
