This tread is like the one with the Yamah 150 Fourstroke on the 18', but with a 1972 21' Outrage...

Oh, Just to let you guy's know It currently has an 125 Evinrude on it now and I think its underpowered. It planes nice and smooth top end isn't to fast maybe 30 mph (just guessing) Anything bigger than that has to be better! It has a real hard time planing when I have 10-12 people in it......(Cruising to the local sand bar)

Easy answer, 175 optimax! Best of all worlds.

I think it would be an excellent choice. We have an old evinrude 140 on our 1971 21 that tops out in the low 30's, but planes the boat easily, and is easy to water ski and tube behind. (it is tough to plane when we have a full load though: 7 heavy adults and 5 kids, but that's rare). We cruise in the mid 20's. Usually anything faster is too rough, give the shallow vee of that hull. I believe a fresh 140 or 150 four stroke would get us a top speed near 40, and that would be plenty for our needs.

As the owner of a Mercury 200 EFI I can say it's a very strong engine, and could be a bit much for a 1972 21' Outrage. I would guess better than 50 MPH, more like 55. The boat was originally rated for 200 crankshaft, not propeller, HP, before any such 200 HP engine even existed.
If all out top end is not your objective, I would think any of the 150HP engines you mention would be more than enough HP. I would guess that the Mercury 150 EFI would be the quietest in operation at running speeds. But if you're going to do a lot of trolling, or worry about start-up & low RPM exhaust smoke, and can pay the extra price, the Optimax or 4-stroke would be a better choice. I've got to say the cost of Optimax oil and spark plugs changes puts me off a little, but maybe the better gas mileage compensates for that. So far, on an HP to HP basis, the bigger 4-strokes do not run as fast as the DFI/EFI's. Maybe this new Yamaha will break those rules.
