Texasmark said:Might trace the tubing back also and see where it originates. Some come from the exhaust manifold water jacket wherein they should squirt as soon as the impeller fills up the powerhead with water......which can take a minute or so....eternity when you are waiting for it to come out :% .
Others come from the output of the stats which are plumed in series wherein the stat has to open before you get water.
Son's '95 150 was plumbed from the stats. We re-routed the plumbing so that it peed as long as the powerhead was full of water. Figured if the stats were a problem, the overheat buzzer would tell us.
Last time I bought an impeller it was in the range of $10. Why would you replace it with a used one......considering how important it is and the pain it is to replace?

Texasmark said:The 150 has a rt angle 3/8" fitting right in the center of the engine right behind the flywheel, on top of the block. The connecting tube goes down to another fitting under the block and drains into the midsection. We cut this and installed the tee that was in the other line coming from the stats to feed the pee spiggot. Then we put a 3/8" plastic union (auto parts store ) in the line from the stats where the tee had been. Piece of cake and works great. Takes about 1 minute at idle on muffs to get water.....block has to fill up first.
To answer another question, the pee comes off a tee using a smaller hose than the thru hose that allows water to circulate from the stats. A clog there would be unnoticeable to the engine function. Essentially that's what we did when we moved the tee to the other hose
