Old outboard motors require just the right touch to start.

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 you’re considering a used boat that’s fitted with one. Here’s a basic 5-step starting procedure you can use to fire-up that oldie but goodie on the transom.

Steps to Starting an Old Motor

1. Engine tilted fully down (this makes it easier for fuel to get to the carburetors).
2. Squeeze primer bulb till firm.
3. Advance throttle in neutral to 2/3s.
4. Turn key on, push to choke (or pull out choke) and crank at same time.
5. Release choke, return throttle to neutral after ignition.

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 application.
