More like an AAA impeller if your peak is 5500-6500

6700

[malcolm]

Wow, that's up there. According to my homemade impeller chart (the Berk chart stops at 550 hp) That puts you somewhere between a B and C. I'm sure you'll get all kinds of different opinions on this though.

[Rondane]

I'd start with the AA then cut to fit your application. Can always go down but not up in cut. Then again for 6700 you'd be around a B. Just my .02

Is their a book a webb site i can read aboat impellers every body tells me different

[malcolm]

Well, so far that's 2 votes for a B.
You might want to ask Duane at HTP for a more scientific answer.

800HP peaking at 6700rpm?
To get to that point, you'd want a Berkeley "B".
Thats according to my new handy dandy JPC.

Yea, too bad that HP doesn't come in lower. A "B" will hurt your acceleration and pulling ability for skiers & tubes some, but maybe not too badly. How long is the boat? I am unfamiliar with a Crusader.
