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.
Starting 2 stroke outboard engine after storage.
I would advise using the ear muffs as opposed to the flush attachment.
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.
2 strokes sometimes need excess fuel to start if not used for a while.
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.
Hard to start cold.
If it refuses to start you can give it a boost.
Pump up the primer ball 5 or 6 times then it takes several attempts to start.
Fast idle lever doesn t help.
Squeeze primer bulb till firm.
Release choke return throttle to neutral after ignition.
I have a new 50 hp 2 stroke on my flats boat.
Starting the motor dry even for just a moment can dramatically shorten the life of the water pump impeller or even destroy it.
Engine tilted fully down this makes it easier for fuel to get to the carburetors.
Understand it has an automatic choke i miss the toggle switch choke control on my old one.
Advance throttle in neutral to 2 3s.
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.
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.
Turn key on push to choke or pull out choke and crank at same time.
Maybe the sound of an unmuffled two stroke is irresistible but don t do it.
Whether you work on your outboard motor on the boat or on a storage stand remove the propeller nut with a wrench.
There is absolutely nothing wrong with running an outboard engine using the flushing port on the engine.
Slide the thrust hub propeller and washers from the propeller shaft.
If you are going to let the engine sit and run for a while which is a pretty good idea to do.
