something's not right, you may have to try spacing down 1" & see what happens, unfortunately there a too many variable's to give you a cut & dry answer. From what I understand most have experienced an increase in top speed with the shorty drive (but every boat is different) You may want to try as many prop combo's as you can. Keep testing.

the sportmaster is 2-3 slower in general, against say an imco. at 80 you are not going fast enough to take advantage of the effeciency of the surfaceing design of the sport master. going down may in fact increase your speed due to giving the drive more leverage to lift the bow thus diminishing wetted surface of the bottom.
try a 1/2 spacer with the same prop with maybe some cup added.
hope you find the sweet spot.

I'm going with a 1 1/2 inch spacing
Note : I got side tracked while testing and working on boat
that my port transom plate water passages rotted out so motor getting pulled to replace it
Owners of older 1989 models keep an eye on them if your in salt water like me !
\nwhen its done will have new test and info ,
running new blower pulleys; new pickups for inter coolers water pressure , 1 1/2 inch drive spacers looking for close to
90 on the gps will let you know!
