I'am considering repowering with Twin Merc Optimax SL 200 , any coments or suggestions regarding them.

If you can get along with less than 400HP, I would recommend the twin 150's instead. They are lighter weight and have a proven track record.
Are you convinced you need clean technology right now? Otherwise I would consider the 200 EFI's, also much lighter and just as strong.
If you have time, you might want to wait for new, supposedly supercharged, lightweight 4-stroke 200's.

Looks like Tate is in California, pretty strict on the pollution regs. I'd go with the Opti or the 4 stroker when it arrives. Only trouble is, I wouldn't trust a supercharger for the 1st couple of model years. They all seem to introduce engines before the faults are known and cured.

where are you guys getting the info on superchargers.Merc has a long way to go on reliability on some current models.

I'am weighing in close to 8700 +-lbs ( the trailer & boatweight). I think the 400 hp is needed, I currently have 200 Black Maxs with 1250 hrs apiece, cruise @ 30 Knots @12gal/hr. I've been told by Mercury dealers that I would increase my range by By 1/4-1/3 with the Optimax.I have a 25' Revenge /WD,.The four stroke is also a option but the weight factor of the engines on the WD platform is a unkown. Perhaps as Ihg stated the EFI may be better.Is mercury comming out with a lighter 4 stroke then thier competitors?I have time to review the options I'am just in the early stage of gathering Info. Thanks for the opinions

There will be a Mercury outboard dealer meeting in the next 30 days or so, and it is expected that the new I-4 and I-6 Mercury 4-stroke engines with superchargers will be demonstrated to the dealers at that time. Earlier this summer some dealers were invited to see these prototype engines running at a technology demonstration. Mercury has been hyping the lower weight and high horsepower of these engines.
Where do we get information like this? From the CEO of Brunswick. He puts it on the web for anyone who wants to listen to it--recordings of presentations made quarterly to investment bankers. See the Brunswick website for the hyperlinks.

With a 25 revenge, the added weight of the 4s might make it sit more static. Revenges seem to be a tad bow heavy.

If you like the Optimax, and wanted more hp for the same weight...twim 225's are the same weight as the 200s. The extra hp would be nice... at a price.
Unlike the rest of the Saltwater Series (EFI and carb) where the 150hp equal the 200hp in weight (and the 225hp equal the 250hp), the opti 150 are about 90 pounds littler than the 200's (443 versu 531 pounds).
So why does a carb 150/200 weight 125 pounds lighter than the Opti???

It is less instead of max:)

Capt - the 200 Opti's are built on the 3 liter block, a larger engine than the 2.5 liter platform. Hence the weight, and also why I'm not recommending it. For a 25 Revenge WD, I would think a pair of 200 EFI's would do 48-50 on the boat. For the 225 EFI's, also an option but pushing the weight limits, speed more like 60 mph.
Or wait for the new lightweight 4-stroke technology. I would not recommend the heavy Yamaha built 225 4-stroke or Opti's for this boat. Might check with BW as to it's ability to handle 1200 lbs engine weight. I think not.
Currently, I still think a pair of the conventional EFI's is the answer. Mine are just super, and more economical & quieter than the 1989 carbed 200's they replaced. They are extremely quiet running and bulletproof, and should give up to 2 mpg. Only real downside is smoke on startup, although they start & respond instantly with the EFI system.
Conventional 2-strokes, with EFI technology, are still good performing & highly reliable engines, in spite of the hype about all the new clean models. The DFI's and 4-strokes have not yet caught my interest for powering Classic Whalers because of the high weight. I'm hoping Mercury's next generation of supercharged 4-strokes will solve this problem as 2006 comes around.

I have a single 225 Optimax on my 25' Outrage Cuddy w/T-top, super consol and an armstrong bracket(similar to your Revenge / WD) Loaded with fuel and as many people and equipment as you want, the boat loves 30 and WOT is over 40. Range is well over 450 miles and the Optimax is quiet and smoke free.
Just my two cents.

Fishcop, Andy, thanks for the info on the 225 optimax, How large is your gas tank ?, I have 140 gal I figure my range @ 225 miles +_, the fuel economy sounds good on your setup.

Standard 140gal tank.
