Could be a stupid question........but

would my Johnson 5hp 2 stroke have a fuel on/off tap like my old mopeds used to?

Only had my boat and engine a few days and I'm new to all this!!!

Assuming you have a separate fuel tank, i.e. tank is not contained within the upper section of the outboard, then start with the tank and follow the fuel line all the way to the carburetor. Is the question just general or are you having issues with the outboard??

It's just a general question, do outboards have a fuel on/off tap like a bike?

I actually have a small internal tank, but want to make sure there's nothing that needs shutting off before laying in the back of the car.

The small engines with internal tanks tend to have a fuel tap on the side to close off the internal fuel tank (at least both my 2hp outboards do), but slightly larger outboards that use only external tanks don't tend to have a tap, as you can just disconnect the tank connector.

When I put our 2hp's in a vehicle, I make sure the fuel tank cap and air breatehr are closed, the fuel tap is shut, and that's it.

There is a lever on the side, but I believe this switches from internal tank to an external tank. I can't see a fuel tap anywhere.

Assuming you don't have petrol in both tanks simultaneously, or the external tank fuel line is disconnected, I guess moving the switch to the external tank effectively acts as a fuel tap for the internal tank?

My backup - Suzuki DT4 2-stroke - has a lever on the side which isolates the internal fuel tank and other than the small amount in the carb means I can put it in the car without leakage - don't forget to close the breather in the tank cap!
I leave the lever in the closed position other than when the engine is actually in use.
The engine can also work with an external tank via a hose the connector of which plugs into a male connector on the front of the engine & is self-sealing when the hose is removed.
