5 blade.
Trying to educate myself on props since buying the V drive . Don't think it's ever been done on a straight bottom v hull non stepped. with a single engine. There are a few with a single VI drive , Phantom has a 34 with a V but it's on a box and that is not a hull to really compare. It's all I really have information wise. The Checkmate with the VI and a 3 blade made and what I assume was a lengthy process of trial /error. A few of the others (Activators)had 4 and 5 blades.
These 2 props are available at a reasonable price. , one is a Mercury and the other is a Hering. Both are the same size 16.5 x 36 18 degree rake .
I figure I can have them dropped down to low 30's if need be ??.. or do I need to be on the search for 17 /17.5 's.
I Don't know propeller dynamics AT ALL..

Drive is a 1.48 gear.
Yes , stock Bulldog . Has 165 hours on it. Going to have Precision Marine tune on dyno.. If there is anything he can do to increase the torque and just keep it all motor I will see . I am not looking to break records , looking have a good cruise speed 50-70 mph.
Any help/advice is appreciated .
Again, I do not understand prop dynamics at all with SSM drives.
