Hello all,

Does anyone have recommendations on which spark plugs to get for the 2000 Seadoo Speedster with the mercury EFI 1st gen. Any help would be appreciated.

Which Merc SportJet engine do you have? The 240EFI took NGK#BPZ8HS-10 And I actually think they all took the same plug. But I would tell if you share the model.

I was pretty sure the Speedster had a smaller engine
