i have an 1979 mercury 80 hp, and it does not stay runing... the only way it will turn over is if i started at full throttle then it will run for a while but if i try to lower the throttle it will shut off... i notice a fuel leak.. it has this blue thing where the fuel line is hooked too ( i think the blue thing is the fuel pressure regulator)... it seems that the motor is not getting enough fuel... if any one can help i will appreciate it, its my first boat and first motor so i dont wanna get taken for a ride if i take it to a mechanic...

Rule #1 Get a manual
Rule #2 Read the manual


You have some leakage. You might need a few gaskets, some sealer and maybe a re-build to the fuel pump.

Can you elaborate on the "blue thing" a bit more? Is it connected to the motor, or is it perhaps a bulb that can be squeezed to prime the system?

We will need some elaboration, a photo would be the ultimate way to convey your message.​

well that blue thing is connected to the fuel hose (internally) if it was a car i would think it works like a fuel pressure regulator.... there seems to be a gas leak where the fuel enters the motor ill work on getting some pics...

If there is a fuel leak, then there is also an air leak which means you can well be running out of gas.​

I am new to this but i enjoy it... i apprecitate all the help :)..... its good to know that there are a few out there who care and helped thank you. !!!
