Author Topic:   CONQUEST 275 Power: Twin 200's or 225's

goodtidings posted 04-11-2003 10:50 PM ET (US)
I am about to purchase a 275 CONQUEST. It is a 2002 leftover according to the dealer. My problem is that it is powered with twin Mercury 200-HP Optimax engines. My research seems to indicate that most of the 2003 models are equiped with 225 Optimax's. What will be the performance and resale ramifications of these engines? Will I be "underpowered"?

I would be concerned about the 2002 optis, as they had some major problems, but supposed to be cleared up on the 03s.
I don't feel theres going to be that much of a difference between the 200s & 225s, the 200s are the same engine as the 225s, just detuned & could be healthier engines because you arent sqeezing more out of them.
I'd go with either of the 03s.
Look at it this way, if the 200s are under powered, then the 225s would still be marginal to.
Twin 200s puts a lot of power to those props, & 225s really arent that much more powerful.

Have the dealer put Mercyam 225 4 strokes on it and you'll have a nice package with resale capability!

I have the Conquest 275 with the twin 200 opti's. The power is excellent. I top out at 49 mph with motors trimmed.
The twin 225's will get you about 3 more mph on the top speed and they naturally use more fuel overall.
BUT,,,if one of the 200's goes down. the other cannot plain the 275 off. It will be a slow ride home. One 225 will plain out the 275 off if the other goes. That's the major difference between the power selections.
The four strokes are nice but you will pay.

Joey, have you actually see 1 single 225 get that 27' boat on plane ?
I have serious doubts that if 1 single 200 hp can't do it, 25 more hp isn't going to make any difference on a 27' boat.

Sal,
No, I haven't seen the 225 Opti plane the 275. There was a past post that discussed this issue. I will have to research it. I'm sure Chuck Bennet over at Whaler could confirm this.

Let me know when you come up for visit. I'd be happy to take you out on the old stomping grounds. Where do you fish now?

The Mercury 200 & 225 Optimax are identical engines, except for the HP rating. This 200 is probably Mercury's fastest 200, because it is based on the 3.0 liter block, and the prop charts show it faster than the 2.5 liter 200 EFI's. But it's big and heavy.
Which brings up an interesting question. What makes the DFI 200's less powerful than the DFI 225's? A black box, and maybe the timing? If anybody knows, I'd be interested in hearing about it. It seems an upgrade in HP would be simple to have done?
I have also wondered about this same issue with Mercury's 150 and 200 EFI's, also identical engines. What makes the HP difference? All of this discussion would apply to other brands also, on a given block.

There must be a network somewhere on the web where the Mercury tuners (we used to call them hot rodders) hang out. I'm sure folks in the go-fast or bass boat circuits have already looked into this. I imagine that anything one might do to turn his new 200 into a 255 would void the Merc warranty.
