Starting Issues

[horaceman]

I have a 1983 Johnson 90hp V4 that I cannot get started. The starter is working correctly and I am getting sparks from all of the ignition coils. I could possibly have salt water in the fuel system. I switched to a six gallon tank from the inboard tank. I can get the engine to fire occasionally but will not stay on. If I have water in the system, any recommendations on flushing?

Howdy, Horaceman.<br /><br />First, drain the carbs. Drain the tank and refill with fresh fuel. Then, with the fuel line to the carbs disconnected, pump your primer until nothing but fuel comes out. <br /><br />Squirt fuel mix into carbs to start her and keep her running until she will run without it.<br /><br />If that doesn't work, you may have a failed fuel pump and/or clogged filter.<br /><br />Install a fuel filter/water seperator in your fuel line between tank and primer bulb.<br /><br />Good luck.

Re: Starting Issues

I removed the air silencer and base to get to the carbs. There were two screws for each carb on the side. I was only able to remove three of the four. Is it imperative that I remove the fourth screw or is removing one on that carb enough? I flushed the carbs with new gas from a six gallon tank. I also checked the fuel filter on the side of the motor and it looked clean. I already had a water seperator coming off of my inboard tank. I removed it and found a substantial amount of water and particles (probably sand). Put everything back together and tried cranking. Still cannot get it to crank.
