CG: Adjusting the CG or center of gravity of the boat has a lot to do
with how tight the boat rides as well as the how the boat “fl ies” as it
exits the water. Moving the battery packs forward or rearward is the
best way to adjust the CG.
SCUFFING: Scuffi ng is a tuning trick boat racers use to increase
the speed of their boat. Scuffi ng involves dulling the area/s of the
boat that touch the water as the boat is running. We like to use a red
scratch pad like the ones you fi nd in the paint section of your local
home supply store. Only scuff the bottom of the boat to the point
the shine is removed from the paint. While this tuning trick is mostly
geared towards the hard core boat racer, sport runners can benefi t
from this as well.
IMPORTANT! Scuffi ng will remove the attractive shine from the
bottom of your hull. If having a pretty fi nish is important to you,
don’t scuff!
PROPS: About the best we can do is help guide you to a better
performing prop. Ultimately how you drive and tune your boat will
determine the best prop for your racing program. Having said that
we have found the GrimRacer 40x52/3 (AQUB9720) or GrimRacer
42x55 (AQUB9725) are about the best overall props for your
SuperVee 27R. It is also advisable that you balance your propeller
when it is new and check it for balance periodically. If you want to
learn more about tuning props check out some of the links listed in
the “National Organizations and Online Help” section of this manual.
You can also learn more about balancing and sharpening your prop

Give your SV27R an added burst of speed—as easily as bolting on
a high-quality copper-beryllium-titanium GrimRacer metal prop!
Racer-designed and USA-made, these are the most accurately cast
metal props available. Ultra-clean casting and true center-bore hubs
place each prop near its balance point right out of the package.
You can fi ne-tune them using less effort than stainless steel props
require—and they hold their shape better for balancing, sharpening,
and changing pitch.
To maximize performance—and minimize damage to on-board
electronics and parts—balance your props with the GrimRacer
Precision Prop Balancer. It’s easy to use. Three thumb screws
provide perfect level adjustment, and a precise bubble level is built
into the one-piece extruded aluminum base. The balancer includes
balancing shafts for 1/8" (3.2mm), 3/16" (4.8mm) and 1/4" (6.4mm)
bore prop hubs. Propeller not included. AQUB9575
