What prop should i start with ?? thanks for your help.

 

[Jayski]

with the smaller 783cc- will my reduction nozzel need to be bigger than 86mm?

Im tossing up between
-8/14 ?
-10/15 ?
-10/16 ?

J have you tried calling Kyle or dan Lamey at dasa? Lyle leaves inn about 2 hours usually

 

[chriselmore_1]

Dry pipe 800 cc gonna be 8/14 or 9/15 with a washer or two.... Not going to be a 10/15 or 10/16, Based on what we ran with our 900cc Dasa motors
