Do you have to run 93 octane?

You should run 93 but if you can't get any, the 275 Verado will still run but will automatically drop the power output.

what do they weigh? the look huge compared to the 2 strokes. what kinda of reliable power will they make if you increase the boost?

Velocity Tom

Im thinking of a 35 donzi zf with 2x275 verados. But what other power options do I have?

Tom,
Mercury Racing just released their 3.2 litre 300XS. I bet it will run rings around the Verado 275 (would make an interesting test). Much lighter and you're picking up 50 HP with the pair.

Yes thats true. But Im sick of buying oil! This weakend I spent $450 on fuel and $100 on oil. My 390 with 500 efis is cheeper to run. But then with the 4 stroke you still have oil changes every 100 hrs.

Tom,
The DI Mercs typically have fairly low oil consumption, and good cruising economy. I would talk with a knowledgable Merc High Perf dealer and get his input.

I have herd that to! the optis use very little oil. I have talked to a bunch of merc. hi perf. reps and thay all tell you the pros and cons to 4 stroke verses 2 stroke. So if I cant find 93 on the water the 275s will de toon and it will not hurt them. The only resone Im thinking of the verado is for re sale .Every boat almost at the miami show had verados.

Not sure about the 300XS but I did a direct performance comparison with the 275 Verado vs a 300X. Had two identical tri-hull pontoon boats with the only exception being the motors. From an idle, the 275 Verado powered toon pulled the other by over ten boat lengths immediately and had a two mph faster top speed. Ran the test several times and the results were the same every time. Hard to beat the torque of the 275 for everyday use.
