Mine ran 106 with the previous owner. Appr. 800 hp per side, Imco Extremes with -2 shortie lowers and extension boxes. Plus, the bottom was blueprinted (everything counts!).
I'm REALLY interested to see what happens with a fresh set of Wesco 540s in it this year (should be about 550 hp each). Also doing shorty lowers on the stock Bravos. My tired old 502EFIs got the boat to 73 (75 on its best day)...it's gonna be a fun spring!
Also...will Caddy be rideable by the weekend? Thinkin' of comimg up...got melted out in Christmas last weekend and came home after only 550 miles

Heading to the Keeweenaw this weekend though, so at least I'll get some miles in. But I digress- thanks to everyone for the advice so far. I'm busy looking into the Imco shorty's and cost to build the setup that has been described by a couple people here (imco shorty's, beefed up internals on my Bravos or B-Max uppers). I don't doubt that the Bravo's can hold the power under ideal conditions, but occasionally I'm not as quick on the sticks as I would like to be yet, so I would rather just build the drives up from the get-go if I'm going to do this. Our boating season is short here in MI, so the idea of a blown drive taking a weekend or two away from me doesn't sit well...
A member here contacted me about retrofitting #3's to my boat because he had a couple complete setups for sale used that he had pulled out of a customer boat that went to #6's... I understand they are making gears for them again, so apparently parts are available, but I don't know much about #3's. Input?

Hey Northerndoc, take all the advice you can get, when it comes down to it if your boat has a 2000 set your going to have to put a lot of power on a bravo to get it to run that fast IF you find someone that knows a transon set up youll go a lot faster with less power, and more depenability. Ive rigged 2
35s that with 525s that ran 115 all day yeah they were race boats only difference being weight. Put the CG were it belongs rig the transom how it should be and you wont have to put the power on a drives that everyone knows a wont take. how much does your boat weight and is it dry and can you keep it dry?

Really Bo, how many people in fountain country can call you by name? Input on #3s your transom isnt tall enough to get them to a good working heigth and what a can you would open in the engine compartment. you like working on it now put a transmission behind the engine think of the room your losing. your also adding a lot of weight. Making your 100 # harder.

Hey guys- bought a 35' single step last summer. Best I've gotten out of it was about 81 mph GPS. That was with two people, half load of fuel,etc. Good conditions, cool water, air etc. Running stock 26 Hydros. Have a set of 28 hydros in the garage for this next year, but am thinking of possibly doing something more. Is it possible to get to 100mph with a set of Whipples or Prochargers? The boat has 500EFI's with B1's at 1.5:1 ratio. Can these drives handle the extra power, or should I be looking at B-maxes or the like to handle the power...? Just looking for some input. Seems like some run the stock bravos and then others upgrade to stouter drives. Is it even worth it with a single step boat?

I have the same boat as you. If a 100 is what you are after, there is no cheap way to get there. but this Is how i would start, I would go with the vortec supercharger. they are less expensive than a whipple but a better package than the procharger. you did not state how many hours are on your motors but I would assume over a hundred, so I would at least do a topend and replace the head gaskets with mls or cometic head gaskets. Next, I have run XRs for years and you can and will break them. How long you run them is dependent on how you drive the boat. The bmax that you mention is hard to get parts for and I am not sure they are still in business. a better choice would be a imco scx drive - next I would go with a 2" shorty with a 1.34 ratio. That will keep you in the 30 to 32 pitch propellers. Your final question is it worth it with a single step boat? That you will have to answer for yourself but for me, personally, the answer is YES.
Hope this helps
