Joe;

Send it down. I will anneal it, bend it, then harden it in the Kiln.

Joe,

[email protected]" to 4.50" max. cup with 8 1/2" OPS 67 pipe on the Picco

H-32 or profiled H-48 on the 67 boat

Waiting for my ABC propellers to arrive from Columbus,Ohio

Thanks,

A 1457 will be the fastest. I ran a stock prop on a Crapshooter. You can try a mod if you want. I think you will have trouble pulling it, especially with a short pipe of 8.5". Start at 9.75" and go down. I ran the 1655 on my 40 RR. OPS 67 pipe is good as well as the AB parabolic.

1657 Octura Stk S/B for a picco 45 Crapshooter 45 for the low 80`s. pitched will run upper 80`s. 1460 works very well also will run mid- upper 70`s. 60 Hydro H32 works very well. 1662 same load a little less lift. Will require you to tip pitch it to obtain the speed desired. I have ran both boats & this is what worked best for me.
