If I remember right you have a GS right Jeff. I have a 225pm and while I am stisfied with the performance it offers on my GS I do feel the need for more power now. Its a craving/addiction I guess. I cant justify for lots of reasons to get a bigger motor at presant,but for a lot less dollars I can do some simple serious up grades to my 225.You can on your 200 aswell like one thing im doing is getting a Brucato ACU that will broden your power band and give you a higher RPM limmit. If you call Tony there he will discuss what limmit you will get baised on what you want,$950.00. Thats the simplest hp/performance upgrade you can make. Now on the other hand if you spent that 1000 bucks and the money you can get for your 200 will that buy you a nice 225pm? The 225 stock will give you maybe better performance than an upgraded 200? I like the 225 for skiing and water sports because they idle so nice compared to a 260-280. They really never load up. If I had two Allisons I would have a drag motor on my other one to quench my thirst when the family isnt with me. Its really like kevin and Bob said depends on what your use is. If ya got a 225pm there light 398lbs and make your GS go 90 for sure. Not sure what your 200 will do? A 225pm with a new ACU limmit at 7500 proped for 7200 will do over 95+! So theres what Im looking for,hope this helps a bit. Ive seen a few 225pm go for 4500-6000 99-2001 lately so what ever your 200 is worth and the diff gets ya going 90,s. A good 280 would be sweet to but looking at around 7500-10500 for a good one, 100mph. I seen your motor on S&F any bites yet. If ya went down a year or two you could get a 250 XS that would be a nice motor for your GS also. Now if I had a super clean 2003 200efi I would trade or sell it and go bigger no Question after thinking about it. My 225pm is a 96 so I would have to lay out to much cash or I would have gotten a 300pm already. When I can thats the motor for me. Then when I buy a new 24ft GS I will can keep the motor :mrgreen: James
