78 Merc 800 80 HP plugs

[mercman]

Any one know what the factory plug is for a 78 (i think) Merc 800, 80 HP, w/Thunderbolt?

Also, what about Amsoil Saber 2 cycle outboard synthetic at 100:1 mix ratio? Pretty lean or what? Amsoil tech says they tested to 200:1 and it is just fine. So which kind and at what mix ratio??

Thanks

It uses a Champion QL76V spark plug. I have never used the Amsoil oil, not sure.

Thanks for your reply. I finally got a call from Mercury and they said NGK BUHW-2, which crosses to a Cahamp L78V. The L78V is a little hotter than the L76V.

Thanks again,
