option 2 Twin 2004 150 Honda 4 Strokes 2.4 liter 480 lbs each
Currently push 38 knots @ WOT 52000 RPM (Until piston stuck).

Should be 200 Black Max's
LHG posted 07-13-2004 08:39 PM ET (US)
With a hull that heavy, I'd consider a pair of 225's. The 150 Hondas ( or even 2-stroke V-6 150's) won't cut it at all. The Merc 200 and 225 Opti's are the same engine.

Yes , it is a heavy hull. On the trailer @ the Scales I get 8180lbs, trailer weighs 2173, with a full tank of fuel total weight of boat is 6820 (140 Gal.)The engine liter size of the Honda 150 and current 200 are the same.

Tates,
Like LHG stated, put a pair of 225 Optis on there and get the smart craft guages.
As I said in my email, you can find an older pair still under warranty. Your boat will do what it is supposed to and fly to the islands!
BTW, Tates has a beautiful 25' Hardtop with Whaler Drive that should be on the cover of a sport fishing magazine.

With the Whaler Drive option, it is better to think of the boat as a 27-footer, not a 25-footer. Twin 150-HP engines on a 27-footer would be quite light power. I would go for twin 225-HP engines.
The fuel consumption should be much better with the Optimax. You will be reducing fuel burn significantly in comparison to the older two-stroke engines.

Thanks for all the great response, Its clear that the Twin optimax 225 is the engine of choice. What differences would there be between 200 & 225 other than top end speed and price ?
The vessel Max Id Tag states 400 hp and 3035 lbs.
I generally run 18-20 knots 3000 RPM into head seas 3-4 ' and 27-30 Knots 4000 rpms in following sea 3-4 '. I very seldom run WOT 38-40 Knots @ 5200 RPM.

Hopefully I will be back in the water by Early August. Andy thanks for the complement on my rig , I'll forward the pictures to LHG and jimh also.

I don't think you would see that much difference between the 200 and 225 Optimax except at WOT.
Myself having a pair of Evinrude 225s on a 27 Whaler WD, far heavier than the Revenge 25 WD, I'm sure the Revenge 25 WD with a pair of 200 Optimaxes would be fast enough for most people. I also think you will see an improvement with the 3.0L 200 HP Optimax over your 2.4L 200 Black Max simply due to the additional displacement.
Since you seldom run at WOT, I think you could save yourself some money (~$1500) by going with the 200 instead of the 225. You will also not be over your capacity plate (the boat can take it but by going over you expose yourself to some increased legal risks in my opinion).

One thing I forgot to add here--while it is true that a Revenge 25 WD should be though of as nearly a 27-footer, most 27-footers such as a Grady Sailfish 272, have an 8'6" to 9'6" beam. The Revenge beam is narrower (8') and so it should not need as much HP even if it were to weigh the same as a Grady, which I don't believe is the case.

The other difference between the 200 and 225 is the throttle control availability. The 225 is available with the new Mercury electronic digital shifting system (dts)which is really smooth.

Well the help I got from you all was awsome. It has been a good learning experience. I have chosen the Twin 200 optimax engines,I should have them next week.
I am now in the process of selling my good 200 Black Max and parts off my burned up one. Preping the "Whalebone" for installation. My local mercury dealer will be installing them.
I'll post the progress and speed results of the Engines.. Thanks again to all for the help .
