Hi, I've just bought a "K8 Mariner 8 HP. Motor No. 680 L 306367, This has got 2 fuel pipes from the remote tank to the motor ( duel connector on motor). Is it possible to convert to single fuel pipe system, How do i go about this. what is the plug gap and fuel mix for this motor Can anyone tell me any history about this k8 mariner 8hp models. thanks

K8?
Dual fuel pipes?

Must be a kerosene motor!

I was thinking the same thing.
Start up on gas and run on kerosene once motor is up to temperature.

Probably what the K stands for.

The tank would also have to have duel compartments

Don't see that kind of motor here in the states so cannot help switching it to singe line

YAMAHA 8hp kerosene PID is also #680
Maybe most parts will interchange.

Incredible how YAMAHA still produce this models!
