This just my opinion, I had a 1991 yamaha150 carb on a pro craft, I bought a skeeter with a 1999 200 yamaha vmax efi. I am running it on 200zx it will push it 72-73 with me and my brother. Starts fine and runs strong, but all the things I hear about the ETEC are good. The only thing I dont like about the advertising is that yesterday on the outdoor channel they had a brand new 30 minute show on it and the only motors they compaired the ETEC to was the yamaha and mercury 4 strokes not 2 strokes. Everbody knows the 4 strokes weigh alot more and dont have the power 2 strokes have. I say you would not go wrong with it. My friend has an 05 triton with a mercury 200 optimax, it is a real good motor. I would recommend a yamaha hpdi.
