    1996 johnson check engine light and alarm

    I have the same problem with one little difference. When i turn the key it beeps and goes through all the lights. has been a little hard to start but not bad. After i start it the check engine light comes on and the alarm sounds for about 10 seconds then alarm stops but check engine light stays on till get on plane. It only does it when at low rpm and comes on and off for different lengths of time. Im guessing its the same as everyone else start checking the fuel lines. Any other ideas?

    An easy and quick check of your fuel system would be to connect a portable tank to the fuel side and try it. If the problem persists it is in the motor. If it goes away it is on the boat side.

    I had a similar problem with an alarm that would'nt go away, it was two wiresw on the tach that were the problem. One was corroded and broke away and the other was a bad ground. Your tach is in conjuction with your system check

    I had a similar issue which turned out to be a bad tach. You can disconnect the sensors one by one and meter them out to be sure instead of ripping the fuel system apart. I replaced all the line and removed the gas tank, learned a lot but also that it wasn't a fuel problem.

    I have a similar situation. 1995 225 rude Ocean pro with Faria Tach system check. Check engine light/alarm comes on when I run engine with a load at 4000rpm/WOT. When I throttle down, light/alarm eventually go away. engine seems to be running ok. light/alarm return anytime I get up near 4000rpm. Replaced the fuel line from tank, new primer bulb.

    It's telling you there is a fuel restriction somewhere coming into the motor. Check your onboard fuel filter.

    If possible try a different gauge if available.
