Ok, my father in law has finally agreed to help me replace the water pump on my 1970, 70 HP Chrysler motor. This is to save me from the $100 labor that the shops around here want to install it. One thing he has asked for however, is the diagrams for the lower unit/water pump replacement. Being that he works on jet engines for a living, and that he USED *(many many eons ago)* work on his own boat, I think we can get it done fairly easily. If you have the diagrams needed and can scan them, pm me for my email address. If you know of a good source for the diagrams, please PM me. If you know where I can get a manual for it QUICKLY, (plan on doing it this weekend or beginning of next week depending on part availability), please let me know. Thank you for all your help!!!
