Soooo... I`m a little confused on DP selection Right now I have a set of G5`s on my Dph drive but my rpm`s are a little low according to VP so to increase RPM do I step down to G4`s or step up to G6`s. If I go to G4`s will I lose much speed

The lower the number (B2, B3, etc), the slower the more RPMs you'll get. When I go from 2's to 3's I lose about 200 RPM's, which I think is normal.
I know B is for aluminum and C is for SS, but what does G designate?

Mike, the G props are for the DPH drive.
This is one of the high performance P/T drives that uses external hydraulic steering cylinders.
No helmet, steering fork or spindle arm.
