Starting 2 Stroke Outboard Engine After Storage

2 strokes sometimes need excess fuel to start if not used for a while.

Starting 2 stroke outboard engine after storage.

I would advise using the ear muffs as opposed to the flush attachment. Hard to start cold. If you are going to let the engine sit and run for a while which is a pretty good idea to do. Advance throttle in neutral to 2 3s.

Pushing key switch does nothing. How to start a two stroke outboard motor engine small outboards mostly have a manual start which means you pull on a length of rope to turn the engine over. Starting the motor dry even for just a moment can dramatically shorten the life of the water pump impeller or even destroy it. If it refuses to start you can give it a boost.

Oil in cylinders as suggested and crank it over few times then 1 2 teaspoon of fuel in the plug hole refit the plugs and start on full choke. Prime up the fuel turn the key and hopefully start and run the engine. Really hate grinding the started. Fortunately the rope is on a recoil spring so it doesn t have to manually re wound onto a pulley on top of the engine after each pull.

There is no reason to start the motor with the notion that you are going to purge the last drops from the water pump housing. Release choke return throttle to neutral after ignition. Squeeze primer bulb till firm. First lubricate the cylinders by pouring a half ounce or so of tcw3 oil in the spark plug holes rotate the engine best you can to distribute it then turn the flywheel by hand a couple.

Fast idle lever doesn t help. Pump up the primer ball 5 or 6 times then it takes several attempts to start. Maybe the sound of an unmuffled two stroke is irresistible but don t do it. There is absolutely nothing wrong with running an outboard engine using the flushing port on the engine.

Start the motor let the temperature rise to the normal operating range and inspect the engine for proper operation. Slide the thrust hub propeller and washers from the propeller shaft. I have a new 50 hp 2 stroke on my flats boat. Engine tilted fully down this makes it easier for fuel to get to the carburetors.
