    Were not getting a spike really merc, it's just jumping to 15 or less. Bought the quicksilver poppet kit, dont have number on me. No saltwater. The alarm was going off before too but I thought low water psi caused it

    Seems me like there still a clog. Bit maybe its sumthin else. I wanna say any clog b a spike n pressure , if poppet not sealed gud it will b little low , the "surge" I seen. like poppet opening and closing. Ur 100% sure everything went back rite with the pump? Hey s&f. am I missing sumthin I'm tellin him , would a clog n head cause lowish pressure?, rooster. Was the old pump intact. ot was there any pieces missin?

    Old impeller was intact, just hard and starting to crack. What wasnt intact was some if the poppet valve and the spring.

    All parts did go back correctly. I turned shaft clock wise when installing top half of water pump cover. Did everything as right as I know how to. Nothing looks wrong with it now. I am thinking it has something in it rattling around intermittently clogging the passages in the block, like part of the puppet valve that was missing.

    i just remembered a situation i had several years ago i installed a rebuilt power head on a customers stump which he claimed he just put in a new water pump , i sent him on his way he called a week later saying it was heating up just like before i asked before what??? he did not mention that while i was quoting him a price so he brought it back i took lower off saw nothing wrong i took it to lake it idled running cool but the minute i gassed it the heat gauge climbed with the speedo so i went back to shop tore out poppet ( i rebuilt it so i did not think that was it but u never know which old man is showing up for work at my house)nothing wrong there took out stats put in washers back to lake same deal back to shop pulled heads put hose diverters in it back to lake same deal back to shop took lower unit off again this time i took bottom half up i saw immediately that the base gasket was on backwards that cuts off about half of the water that should be coming thru so another deal of just not watching what your doing bites again maybe thats it good luck PS inspect the metal plates in your pump if do did not replace them you should because if they are scored very deep it will affect you performance

    Right Merc, before we started we had zero water pressure at idle and maybe 3-6 at wot. Here is a list of what we have done so far following merc specs in the book. Water pump kit, poppet kit, tstats with new grommets, and mid gaskets. Now we have more pressure but its intermittent from 5-12 psi. It will idle decent but 5 seconds after you go wot and jump on plane it overheats.

    Sure sounds exactly what bobby sayin (texas) also hes lot better at these than I am. So with that said. R u 100% sure the metal plate went back in right in water pump and if so.base gasket mite b upside down covering g wrong holes for flow. But fine at idle

    If base gasket gets flipped it dont fit water passages just rite. It will "fit" both ways but only work 1 way

    Im pretty sure, as I lined it out with flow path of the metal plate. Were gonna pull the lower tomorrow and flush it, I will check it again as I installed the new one like the old one came out. Maybe the old one was in wrong the whole time idk.
