thanks,I have xr's just got the labbed back will try them today on my way to cambridge, they have the steel insert, does that make the b1's fix xr shafts?

you are up in horsepower.........could you be down in torque?

no the torque is well into the 620's... I did run with the labbed 26's and it seemed better, didnt get a chance to air it out and really test the intervals. have to align the throttles to have the motors running the same rpm. port side is 400 revs more at the same position. Once I get these little things straight I can get more accurate numbers. I may try some box 24's as well...It just freaks me out to make more hp and have to run smaller props, this boating thing is crazy..

THAT Happen to me made more hp hit a wall put on a nickerson carb and a 2'' shortie hitting 5600 to 5800rpms with lab 26 was hitting 5100 74 before. old carb jetting was way off looked good on the dyno 647hp tq was 627. will re dyno this winter with new carb and head work.

update:
Thanks to Brett at BBlades we have it figured out, tried some 24 stock and the RPMS flew to 5700 and the boat peaked at 73-74. It was hard to tell as it was kind of rough out. I am shickled titless at what JC did with my motors, hearing those things at 5700 is amazing, I have to get used to it. I'm going to have Brett do my 26 lab work and it should still be at 5700, I will also get a set of 24's to have as spares. Bretts calculations have the boat at 76.5, I'm hoping he is correct.

Oh btw, i had a local company depitch and "lab" my 26's, and it was 500 bucks wasted, I'm not mad, but next time I'll send it out and make sure it is done right by people that are experianced in hi perf apps.

I highly recommend Brett and his test program!!! thanks again for all your help, talk with you soon...Rob

Who did the work locally Rob?? I wasn't aware anyone is "labbing" here.

Millers Island, when they came back they were stamped 25, so I guess thier idea was to depitch them. I heard when the driver dropped them back off that he told the guys at the shop they will never do that again. I wish they would have just said, "no we dont do that type of work" Oh well it's only money huh?

Hmmm, 25 huh? That might work for a certain Formula I know

I have xr's we can get the hub adapter and try em out, call me and let me know, I'll be out next weekend..will be in vegas tues thru fri.

I had props repaired by them. Had to send them to Throttle Up to have fixed, but Matt did a great job. Good props only go to Florida for us now.
