I noticed the pee hole on my outboard was blocked while testing at home and unblocked it using a thin piece of wire, it started pumping water great and left it at that. However i took my SIB on Windermere at the weekend and after about 5-10mins noticed the engine seemed a little sluggish i checked the pee hole and noticed no water was coming out, foolishly i hadn't takedn any wire out with me so had to make do with what i had on board (which wasn't a lot!!) and poked around for a while and a trickle of water appeared which was like boiling water. I presume this was because it wasn't exiting from the engine and got hotter and hotter??
When i tried to start the engine again it wouldn't start, i put my hand on the cowl which was v. hot! I had to let the engine cool down before it would start again, i limped back to shore (minimal revs) and tried to clear the obstruction but it didn't budge. I had sandy grit coming from the pee hole so it must now be blocked with a larger piece of shell or similar.
I don't know anything about outboards so was hoping for some advice on here, hopefully i haven't damaged the engine by overheating it
but how would i go about clearing the blockage?
Thanks in advance
