Re: mercury 200 efi vs 200 optimax
These are totally different engines. The 200 EFI is a 2.5 Liter and the 200 Opti is a 3.0 Liter. I just traded my 225 optis for 4 Stokes because of reliablity fears. I am told by my dealer that EFIs are reliable. They will burn more fuel, but shouldn't smoke much more.
