Clogged thru hull fix DISCOVERY…
First, I was running the engine while on a mooring at Catalina island to charge my batteries a bit. To my surprise when I went to shut off the motor I noticed the temp was WAY over!!
Water was coming out when I started it.
I first pulled the impeller cover to inspect it and no water came out but the impeller looked intact.
Next I opened the strainer. It has some debris, but not enough to clog it. And no water was coming out at all from the strainer that is mounted right on top of the thru hull.
So, my next thought was: how am I going to unclog this? I have nothing to connect to it like a hose to backflush it. It’s night time and cold and I’m not diving. What else could I do? Was there something I could shove down it to clear it?
Then I ran across a post online where someone used their airhorn pressed against the strainer housing. Genius! (@Roland gendreau

I closed up the impeller housing and made sure nothing else could stop the air going OUT, then I pressed the horn flange against the strainer housing as airtight as i could and gave a couple quick blows. Lo and behold I could hear it unclog and water started flowing!! Holy crap. It worked and whoever thought of it is a genius. I can’t take credit but I wanted to spread the knowledge!
Photo is not insitu but my old strainer I placed the air horn on so you get the idea.
