This is my first time owning a boat,picked up a 67 14' alumicraft to get my sons into fishing. Glad to see there are helpful forums such as yours to answer novice questions. The motor i have questions on is a 7hp Chrysler model 703 serial 4576 year 1969. My boss was given it a couple of years ago and told the only problem was the fuel pump. He recently gave it to me as he had no time to repair. Upon getting it the fuel pump was disassembled. I purchased a repair manual and gasket kit and went to town. The repair manual though shows a gasket between the powerhead mounting and diaphram then the reed plate then a second gasket and cover. The kit has a third gasket that looks the same as the one that goes against the powerhead. There was no diaphram when i recieved the motor but it appears to have had possibly both gaskets that look the same between the reed plate and the powerhead and im assuming the diaphram between the 2 gaskets. that is how i assembled it but not sure if its correct. I tried to get gas through and found inlet line to pump was pinched and plugged so it wasnt recieving any gas to pump. I replaced the line and primed with bulb and got good gas flow out of outlet of pump but when i tried pulling starter rope i did not get flow out of pump. This is why im questioning the 3rd gasket placement or could something else be wrong. I pulled about 10-15 times till my rope broke but no flow unless using the primer bulb.Also if you can tell me the correct fuel / oil mixture. I see alot of the chryslers use 50/1 but have seen also the 6hp model at 16/1. My manual does not say.<br />Also any help where i could find a breakdown of parts would be helpful.I would like to replace waterpump impeller also but have not had any luck finding part numbers for this model engine. Thank you in advance for your time and any imput you can give me on my little project.
