Alright so i started on this boat with a seized slant 6 in it. its a 74 chrystler with volvo outdrive. ive got it to the poin now where the motor is running perfect. questions i have now are about the cooling system. Its got a sherwood dul impellor pump run by belt from motor. Im not familiar with systems like this there is a valve on a hose going to the bottom of intake manifold from a union supplied by the water pickup hose that when shut allows water to pump up through the pump but when its open it stops pumping.also motor has been overheating and i cannot for the life of me figure it out, theres no blockages in any of the hoses or manifolds. seems like pump is picking up water fine with that valve shut but not circulating through the motor. seems to me like possible backward hose or something but i have no idea how its all supposed to be routed. i know this is a long post any advice is appreciated.
