I would leave the drive at the stock depth and try a 27 p5x. I think you will be happy.
Otherwise, throw the 1 inch spacer on her and go with a merc lab 28.
Glad you are getting things sorted out.
I find that each time I do a motor or horsepower mod, I have to re-do the setup on the boat.

I got my 26 4 Blade back from BBlades Saturday and today I tested them both ....
So my test was 26 Labbed 4 Blade Against 26 P5X ....
my Boat is an 05 Heat with a 525 and a 1 inch spacer testing was done on the mississippi River with about 1/2 load of fuel with my Bow cover on.....I made the excact same run with Both props .....
Top speed with the 4 Blade GPS was 74.9 and just under 1/2 Trim ....If I trimmed any higher I would hit the rev limiter ....So at 74.9 Just under 1/2 trim I was at 5300 RPM ....But the Boat was real Unstable with that Prop in comparsing to the P5X..
The P5X top speed was 73.9 GPS at 5250/5300 RPM ...trim just above the 1/2 way mark....But the Prop keeps the Boat so much more stable .....
So my Decision is to Buy the P5X .....the prop just hooks up so much better then the 4 blade ........I felt I really had to keep both hands on the wheel at Full throttle with the 4 Blade where the 5 Blade I was much more relaxed .....The 5 Blade is expensive but well worth it I think .......
Anyone interested in trying one BBlades will let you try one for 14 days for $40....

Everything Helps at this point, thanks....
Took the boat to the lake today with the standard XR and the 28 B1 that I've been testing with. WOW!!! BIG difference. The boat came out of the hole really good and FINALLY didn't blow out. Still alot of slip, but a noticeable diff all through the rpm range. Throttle reponse was pretty good, and the handling was WAY better. Not sure how just the sportmaster can make that much difference, but IT DOES!!!
Prop is currently 3 3/8 below keel - approx 880 elevation - 82 degrees
Boat ran 74mph (garmin gps) at 5300/5350
Hi Derek,
Well, Were do I go from here? you guys are the experts and my brain is overloaded at this point. One thing is for sure, I am MUCH happier with the standard XR even after one test run.
I did have a B1 26 with me and didn't test it, should I??
Thanks, Derek

Sounds like you are getting close. With the RPM you are running now with the 28", the 26" will just put you into your rev limiter. Time to test props.
Congratulations

Congrats Bent. The Hydros are nice out of the box, but I'm sure Brett can find you another MPH or 2 with some minor tweaks. I would just keep it simple like sharpening the leading edge, pitch matching the blades, and these boats seem to like a little more than stock cup.

I think you'll have a great time with it like it is. Ran my new 30" P5-X this weekend. Smooth as silk, efficient in the midrange (50 @ 3500, 60 @ 4000, 70 @ 4500), and fast
.Best Regards,
Steve

Maybe I'm doing this backwards, but I put a 1" spacer on last night to test. gonna try the stock B1 28" in the morn. Still gonna order a p5x, this was just faster cause all the parts were here. Prop shop said if I let them know soon the can Lab/add cup/tweek the prop by the weekend. How much should the spacer bring the rpm down? anyone got a p5x for sale??

You should see a noticeable reduction in slip with the 1" spacer with a B1. It really helps the 4 blades to run them deeper, because they have less blade area than the 5 blades.
As for exact #s to give your prop man, you really should run the prop and note speeds at varying RPM, holeshot, and lift, handling, and speed/RPM at WOT. If you give your prop man this accurate information he should be able to do a nice custom job for you.
The P5-Xs will also run with fine with the spacer, even though you may be able to run them without it.
Regards,
Steve
