    no not the base gasket for power head but base gasket for lower half of water pump most people dont change that part of the pump for what ever reason but just the impeller and the two gaskets and metal plate if you pull up lower part of pump you will see the base gasket for thats part of the pump that what was backwards sorry for the confusion

    Only thing that bothers me is how much water is coming out of the top 2 exhaust vents. This is a 200 powerhead, and the mid is a 150. Could the adapter plate be causing problems? Were lost

    Think we may have our answer, started looking at gaskets that were on the mid originally. They are 92 and up gaskets, this mid is an 86 according to the serial. The gaskets for the mid to powerhead are completely different in the pics I can find. So we have the wrong mid gasket. Would this cause our problem? Thanks

    I think that's 1 reason I blew my 1st 2.4. I had way to much pressure and water didnt have time pull heat out of block

    Well we got the new gasket on tonight that matches the mid. Psi is still low around 2-3lbs at idle. I will say this, when we run the throttle up it sucks the hose dry and doesnt give a good psi reading. It didnt do this before so were going to lake test and see what we have. Also ran compression test just to make sure we didnt have a bad head gasket etc.. Motor was from 117- 119 on all 6.

    Ok rooster. I will say it again haha. That is perfect pressure for idle. What kinda pressure u lookin for at idle? More pressure isnt good. When u drop n lake and put in gear at idle it will drop little more but that's fine to. U have normal pressure
    Also when u do get to wot. U dont want more than 15lbs
