If you have a separate portable fuel tank, try connecting that and see if the motor will run.

See if you notice any contamination or water in the fuel when you drain them, as that might be an important clue. Hopefully, you have spare fuel filters onboard, so changing them shouldn’t be a big deal. If it starts briefly and runs off of the starting fluid, then you know with certainty that the problem is with your fuel system.Īt this point, it’s time to start double and triple-checking the fuel lines, primer bulb, and filters. You want it to go more or less straight into the manifold. Take the cowling off of the motor and spray a short blast of fluid into the air intake. If you’ve inspected everything and are confident that the engine isn’t flooded, the sure-fire way to narrow down your troubleshooting is to get a can of starting fluid. Some motors are very susceptible to flooding, while it happens to others very rarely. Give it a few tries, and if it doesn’t start, then wait ten minutes or so and try again. The cure to getting a flooded motor to start is to close the choke and open the throttle to half or more while starting the engine. It usually results from repeated starting attempts with the choke or primer out. A flooded engine has too much gas in the system, and not enough of it is atomizing to combust. It’s also worth noting that the engine might be flooded. If you have a fuel water separator with a sight bowl, check for contamination. Check all fuel line connections and hose clamps. Prices include shipping in the continental US. Parts manufactured by CDI Electronics meet or exceed OEM specifications. Listen for unusually air sucking sounds as you squeeze. Save on stators, switch boxes, triggers, rectifiers, voltage regulators and internal wiring harnesses for Mercury and Mariner 75 HP outboards. Squeeze the primer bulb and make sure fuel is flowing. Is there fuel in the tank? Is the fuel line in okay shape? Do you have a fuel shut-off valve, and if so, is it open? Even a small air leak can lead to starting problems, especially if your motor is fuel injected. Check the fuel system step by step, from the tank to the motor.

Be sure to do your testing under your normal boating conditions and with a good propeller (not bent, cracked, or excessively chipped). You want your RPM's to be within the proper range while at wide open throttle (WOT). For example, if you look at your tachometer at top speed and it is not within the engine's RPM range then that is generally not good.

On manual or pull start motors, pull the starter rope 4 or 5 times for every cylinder you test. If your motor is equipped with an electric start option, count the number of second. Zero out the gauge after testing each cylinder. Your engine's RPM range is important in choosing the right propeller for a given application. Crank over the motor the same amount of times for each cylinder during testing.
