Drive Height For 24 Ft 24degree V-bottom .

[Skater 32]

I RUN A 24 FT , 6.5 BEAM , 24 DEGREE V-BOTTOM RACE BOAT WITH A IMCO 12 STANDOFF BOX AND A 2 INCH IMCO SHORTIE . MY PROP SHAFT CENTER LINE TO THE VERY BOTTOM OF BOAT IS , 2 INCHES BELOW , KEEP IN MIND I HAVE A 12 INCH IMCO STAND OFF BOX . THE BOAT RUNS 80 MPH , SWINGING A 30 INCH HYDROMOTIVE QUAD 4 -X , BY THE WAY , BEST PROP I EVER USED , INCLUDING MERC LABBED BRAVO ONE . THE BOAT RUNS WITH DRIVE ALL THE WAY IN , AND HAS NEVER , NEVER CAVITATED . ANY BODY WITH SIMILAR SETUP , AND WHAT IS YOUR PROP-SHAFT CENTERLINE TO BOTTOM ? lARRY

that sounds about right. how much trim can you use before excessive slippage...

It will never cavitate , ever !!! I can start out with drive trimmed out . Does anyone on here have an I/O on an 12 inch set back box on a non stepped bottom ?

SOMETHING IS NOT ADDING UP??? YOU SHOULD BE RUNNIN BETTER THAN 80 WITH A 30" PROP.
WHAT IS YOUR GEAR RATIO AND TOPSPEED RPM???
JUST CURIOUS CAUSE WE RUN A 24' 24 deg bottom WITH 1.5-1 BRAVO 1
WITH A 27" MIRAGE 5400 RPM @ 78-79 MPH AND NO STD OFF BOX
X-DIM IS STOCK FROM BAJA SO IM JUST COMPARING, WHAT HULL AND HOW HEAVY IS IT?:confused:

I race with a 28 bravo one and it the best it ever ran was 82 @5200 . I run most of the time with a 30 for better cruise speed , 1.50 ratio . by the way , the readings are GPS
