Here is my Grimracer setup.

Aquacraft SuperVee 27
Entire bottom scuffed with red scratch pad (Menards, Lowes, etc)
One thin cote of Pacer Z-Poxy Finishing Resin on all wood parts (#PT-40)
SS trim plate’s .5deg positive to the bottom of the hull
Strut set at 0deg
Rudder blade tucked full under (stock shear bolt)
DTX 3800s (two 6 cell packs)
Added turn fin to the port side (AQUB7882)
Octura X-440/3 prop (bag)
Top speed… 38MPH (note: the wind blows almost all the time here, typically our water is loose) so this is a great setup for 12 cells...using this setup exaactly and adding 14 cells what type of performance increase can be expected...im guessing 15%-20% excelleration increase and 3 to 6 mph increase ..being new to boating not sure so i thought i would ask the vets...thanks
