While newer outboards start right up, older outboards can require a little more know-how to start up quickly and correctly. If you are restoring an old boat or considering the purchase of an older used boat, read the article below for more information on how to start a Carbureted 2-Stroke Engine. Also remember, today’s high-performance outboards provide incredible power and require very little maintenance.

Outboards start like a car; just tilt them down and turn the key. At least newer ones do. But it wasn’t always that way. In the past, you had to learn how to start an outboard motor. Carbureted two-strokes can be fussy, especially when cold.
Now, there’s still plenty of carbureted two-strokes in service. And how to start a 2-stroke outboard motor is as important as ever. Maybe you own one, or maybe you’re considering a used boat that’s fitted with one. Perhaps it’s an outboard in need of a rebuild. In either case, here’s a basic 5-step starting procedure you can use to fire-up that oldie but goodie on the transom.
Five Steps to Starting an Older 2-Stroke Outboard Engine:
- Engine tilted fully down (this makes it easier for fuel to get to the carburetors).
- Squeeze primer bulb till firm.
- Advance throttle in neutral to 2/3s.
- Turn key on, push to choke (or pull out choke) and crank at the same time.
- Release choke, return the throttle to neutral after ignition.
Also, make sure the tank is vented. If it’s a built-in tank, make sure the vent fitting is not partially obstructed by an insect nest or wax or something.
Takeaway: Outboard engines are the only propulsion designed from the drawing board specifically for marine applications.
