You also need to think about the prop pitch you are running. One inch up from the bottom and 36" bravos are tough to get on plane and almost impossible at the start of a poker run, even with a tab. Five blades are better, but if you are taking off in a poker run, it still can be tough. 34" bravos are OK and 32" bravos are no problem.
Another thing we found to keep from blowing out if using MSD distributors, is to lock the advance. That way you don't have one advancing ahead of the other and blowing one prop out and killing you. This can create other problems.
The best thing I did to keep from blowing out a prop on a start at a poker run was to install intercoms. I keep my ass in the seat and watch the tachs. My navigator stands for the first few seconds and tells me where to go and until we roll over. This also allows me to have my lap belt on before we take off.

I run the P5X's now and wouldn't think about running 4 blade Bravo's again.
P5X benefits vs. Bravo I's
Absolutely no more problems rolling boat over, no more blow outs or pumping the throttles, 4 mph increase at 3500-3800 rpm, smoother and better throttle response, brings the nose down and maybe a 1-2 mph loss on top end, but who cares everything else more than makes up for the loss on top. I never run full throttle anyway.
I highly recommend you try the Hydros, seriously.

Re: 28 TD Daytona x dimension question?
The 5 blades seem to be causing some drive failures on the higher hp boats around here. I do want to try some P5Xs. I have a friend with P5s. He likes the midrange, but that is about it. Another friend can't keep drives together with Mercury 5 blades and 750hp. He runs idle or full throttle.
We have slowed down at poker runs with so many bigger boats now, we just pick a speed to to enjoy the ride.
We cruise a lot on river trips and the extra midrange would be nice.

I don't have enough hp to tear anything up, so that's not a concern.
Aren't you running hp500's?

I'm trying to round up a group purchase on shorties if anyone's interested. I'm going to get a set if the price is right and if we can get enough guys together to make it happen.

Re: 28 TD Daytona x dimension question?
Harper220, I just read your offer to put together a group buy on drives. You say your drives are 1/2" - 1" above the lowest part of the sponsons. You really need to measure right in front of the prop shaft to get your dimension. Eliminator did not always use the same distance between engines (drives) back in in the 1999 - 2001 era. Measuring the way you are in reference to the lowest spot on the sponsons, the farther apart the drives are, the lower the X dimension.
Be sure to measure both sides, I saw a 30' where there was an inch difference between sides.

Re: 28 TD Daytona x dimension question?
In these pictures, does it look like I'd be safe going up 2" with IMCO shorties? I'm roughly 1" below bottom directly in front of the gearcases.
This would put me at 1" above bottom. Would this make sense to do?
