Anyone running -2" shorties on a 28 Cyclone? Looking for feedback.

SABER28

curious too, i'm sure i'll be blowing up my drives soon and need to replace them.

Just upgraded to XR gears and in the process found out they were 1.36 when I bought the boat. It explained many of questions I had regarding RPM, etc. We are converting to 1.5 with the swap so I know that will dramatically change things but was wondering the ideal drive height.

FunHome

I have -2 Sportmaster lowers on my 28 Saber now. I've been running them for years. I tested with a set of -2 imho lowers and they were a couple (2) mph faster.
Standard lowers were way low on my boat, that is why I opted for -2 shorties.
Any other questions?

So it's been a while since any discussion on this. I have completed engine builds and converted the drives to XR hears with Drive Guardians. Like FunHome I feel my drives sit way low, I have to trim to between 6 and 7 for top end and they sit way deep, Not that I'm looking to, but the boat could not kick a rooster trimmed up if I tried they are that deep..
I'm thinking this is a winter projects just checking to see if anyone else has experimented.
Thanks in advance.
I'm currently spinning a 32 Bravo 4 blades with a 1.5 if I don't go shortie the props need a massage to pick RPM to where the builder wants them.

i actually talked to doug about this a month ago. he didnt think going to shorties would make much difference.

on a different note, swapped my 27 pitch 3 blade mirage props for 29 pitch ones. boat wouldnt hit 90 (93-94 before) and the whole boat shuddered when turning corners. were they overloaded? my motors turn 5600 rpm with the 27's but would barely break 5000 with the 29's.

I would listen to Funhome. Think he has the fastest twin 28 currently.

I have always thought the drives were really deep on the 28s.

SABER28

ballistic and mine both run 90's with stock drive height. i think funhomes is in the upper 80's.

I'm running low 90's now with a best of 93 GPS 91 and 92 depending on the day.. They do seem deep and was thinking shorties over the winter.

As deep as they are I'm not sure if I will pich up anything. I guess thats why I'm asking don't want to spend useless money.
