Blaster Shortened rockered 1100 B1 with 155 pump.....what prop?

[PowersportComposites]

I will be doing a build thread for this ski....once its complete. But for now I am trying to figure out what prop I should run. B2 155 pump with Kawi 1100 stock (for now).
The hull is
-6" and Im aware it will porpoise a lot. I plan on making removable hull extensions, so I can run -6 or +2 on any given day...
I know these prop pitch secrets are closely guarded in the racing crowd so a PM would be just fine if someone has first hand experience and doesnt want it posted publicly. I would really appreciate the input.
Sneak peek....

Alot of the blaster guys are on pwct, I'm running a 144 16/23 skat mag with an 1100 yam but thats no help to you with the 155

Ski looks great though, u did a nice job on the nose.

Sick hull mods! Sorry, no help with the 155.

 

[ChadGnarly]

I think the aussies have a 155 pump with a dasa 1100 b1 on the X, that may help. Ask impros.

 

[PowersportComposites]

K guys thnx. Ski has graphics now but no pics till its turfed

I want that blaster, holy crap! It seems as if you're going more for freestyle, so you may want to hit up the rad dudes. I would think something lower like a 11/17 or maybe a tad taller to stretch out that motor, but you still want that punch out of the hole. Again, not much help. Chadgnarly on here or twinturbostang fron the rad dudes crew may be able to help you. Good luck.

I have a b1 gp1200 motor and 155 pump. I have a concord 13/19 impellor, the guy that builds skis i get my parts from said that pitch is an all around good pitch. I don't know if thats true and i don't know how much bottom end the ski has cuz im waiting for a midshaft to take it out on the lake. Hope that helps , Mike B

 

[PowersportComposites]

thanks guys ill keep progress updated. I will start a build thread here shortly

Ha Mate. I run a 1200 Yami in a stock B1 and have done a thread on Ozfreeride. This might be of a help.Dave. http://ozfreeride.com/index.php?threads/blaster-1200-conversion.6854/

Looks like a fun ski.
We tell everyone to call Impros and tell them you are running a rad dudes Kawi setup and what all is done to the motor (head, carbs so on).
I'm sure they will set you up right even with the 155. Those guys know their sh*t

 

[PowersportComposites]

Dave recommended a Solas Concord 12/18

 

[Twinturbostang]

Nice when's it coming?

 

[PowersportComposites]

Should b pretty soon I hope im very anxious. I'm waiting on a heap of other parts too though

 

[Twinturbostang]

Can't wait for a ride report

 

[PowersportComposites]

Wait till I post pics of after graphics. This thing looks nasty

Good looking ski! Cant wait to hear how it rides!

Any way to get pictures of the pump area and what you had to do to get that to work?

 

[PowersportComposites]

I can take pics of the pump area but I'm not sure what you're asking? I'm assuming you're not asking how I did the glass work you're no stranger to the itch....
I havent installed the pump yet but I'm just going to use the JD155 aluminum pump shot. B2 pump bolts right up...to my knowledge. Now the removable hull extensions is a whole different story. That will coke a bit later. Right now I just want to ride this pig

Kawis need to rev to make power. In a 155, IMO you need to be down around a 9/15 swirl if you want it to rip.
