Bro just got a 2002 175 Merc hock it to muffs no water came out pisser hole for alittle more than a min then not real strong but it was pissing.impeller? Or do this bigger motors need more water. Or higher rpm. New impeller last year only 10 hours old.
2002 Merc 175 efi piss hole ?
I believe eyesman is on the right track... Some motors tell tale stream is after the impeller but before the t-stats, this is why you get water right away and it always is cool, and others are after the t-stats so they don't open until around 135 or so, so the water will always feel warm. I'm guessing yours is after the t-stats as it took a minute before the tell tale stream was visible.
I'd take her out on the water and see how she does.
I have had that happen.. I have use a paper clip to stick in there but I have seen the guys at the boat shop use a tiny drill bit. Make sure to check if it has low water pickups. If so you need to put duck tape on them before running it on muffs. I am not sure if that lower unit has them of not.
I cannot speak directly to the 175. My 225 pee's a good stream all the time. My buddy did have a 150, that seemed to have a weak stream all the time. I know some guys have used a bottom bouncer to clean out the hole, but that always makes me nervous. I now keep a 2' long piece of trimmer string in the boat to clean it out. In my mind less of a chance of pushing a wire through the side of the hose.
