Now after the new impeller and housing along with the new stars I've noticed it starts peeing the minute you start it up... what would cause the difference?
I recall waaay back in the day my 92 175 did the EXACT opposite thing and i never quite have ever put my finger on it. When I replaced what I believed was the factory installed impeller and housing......wham, it changed how it pee'd at startup. Where from before it pee'd strong from first startup, muffs and lake........
Everything was assembled properly ya ya ya, just somehow changed it ever so slightly now it takes a few minutes to pee (stats cracking open) and the stream seemed to weaken a bit too. Internal pressure is within spec, stats all good, not sure, maybe it was all a dream or something I ingested back then........
Since then I probably have changed impellers a couple of times along with housings and wear plates etc and it never has went back to what I recall as the "original" tell-tale functionality
I've always used merc OEM parts BTW. My guess is there was a slight design change.
My best guess is....Since the original impeller/housing had never been changed (No P.O.) there was only slight wear on the impeller BUT the housing base and cup looked like it had gotten a bit hot and the plastics melted/flowed a bit around the SS impeller cup and base plate. I figure the motor must had been fired up somewhere along the road before I got it "just for a sec" with no water and the "instant" pee I recalled was not proper pee...........Proper pee came after I replaced the parts a few years (94/95) later.
Long story longer..........That era of motor seems very "touchie" in the pee area, some pee different when on muffs verses in the lake, (mine does, always has, or used too, I forgot, it changed) some don't. If yours was worn slightly one way or another, it now could now be back to norm, check the stats, pressure and idle/running temps, if they're the same/in spec..........run it!!
