blackhawk props
 

Looking for a set of 29 any out there please.craig

Would you happen to have a set of 27s for sale?

Yes I have 27 and 31 in excellent shape but right now im trying out 31 on the front and 27 back we are in the testing phase.I tried spinning the 31 but just not enough power with 525 hp

also try hoss propellers...they made some of the props for merc..i believe they also have the castings to make new ones..

Thanks guys I don't now what to do.I re did my 18 donzi to 350 mpi with a whipple charger pushing 525 and I that for sure I could spin those 31 but im running 74 mlp at 5000rpm and so im trying the 27 to see.but thanks for the help.craig.

Would you sell the 31s?

I will loan you a set to try if you are close to new jersey

Thanks a lot excal27 that is very kind off you but I live in Kitchener Ontario.I would do the same for someone else that would need to try props it's a expensive try.how much power do you need to spin these 31if I have to ill do aluminum heads bigger gaskets and more boost.so no I think I could never sell the 31 or any props they are a great drive if I can get my hands on another one I would be all over it.thanks guys craig.

I might be selling one you can pm me your phone number or i will give you mine

If you could pm me with your number that would be great to chat thanks.

just a word of caution and someone correct me if im wrong but I thought I read that they tested mis matched pairs at lake x with good results in performance but it was very hard on the lower gears. Ate up gears rather quickly.

Hey Craig, you can also have the 31s labbed to get a little more rpm and they should spin a little easier. also what gear size are you running?

I didn't think you could take pitch out if I did can I put back in.gear is1:50 ratio I should now today hiw the 27 did im hopping 80

A lower gear will help you spin them as well, im running a 1.36 in mine.
