I think some folks are comparing apples and oranges here, 3700 rpms would maybe get me on a plane.

I owned the same f225 on my 21 Paramount. I thought it would work out well but the first gen 225 were identical to the 200 except for the cowl sticker and price. At the time Yamaha utilized the industry fudge factor to pass a motor rated at 205 hp as either version of the f series. As far as the 200 hdpi goes.... It is over 100 lbs lighter than the F225 of that era and tested at the prop to 215 hp. I will also say the 200 hdpi was one if not the best hdpi of the series and absolutely apples and oranges compared to the f225.

A Paramount is a completely different hull design. I actually had a 21 Concept with a 200 Ocean Runner and the boat ran well but was not a speed demon. 200 HPDI is a great motor.

Agreed. My point is only to illustrate what is on the sticker is not what is always under the hood. Not all 200s are created equal by any stretch of the imagination.

From the test I posted above it appears the i4 f200 is another Yamaha ploy to sell with the sticker. That is why I feel the i4 f200 the OP is questioning is not enough motor for a 23 SC. The torque curve of a 4 stroke 4 cylinder is of no comparison to a direct injected V6 that is rated above it's cowl sticker... and torque is what a 23 foot offshore, deep V boat requires.... not a "200" hp 4 cyl motor that is at best marginally peppier than a 150 on the same boat and identical at cruise speed.

I agree. I don't think a light duty I-4, 4 stroke Yamaha 200hp is enough motor for the 23. Too weak and pretty heavy too (Compared to a 2 stroke)

That was my point back on post #3. As mentioned above the 3.3 225 Yamahas were really wimpy engines (Moose is right on his numbers), however the Yamaha marketing machine sold a bunch of them. They are doing the same with the I-4 200. Again I do not have personal experience, I'm going by other folks opinions. The Maverick forum had this same discussion a couple of years ago on this engine and that's where I got most of my info. What you don't want to do is compare the Yami I-4 200 to the eTec 200HO, it would be embarrassing to the Yamaha with the difference in actual power/torque. Crazy difference.

I had a F150 on my 22' Pathfinder I just sold so don't think I'm anti Yamaha.
