higuys what isthe best trim or indicator numbers should the drives and tabs stay for the fastest speed thanks

There is no way of knowing that.

You need to determine nuetral for tabs and drive(s) with a straight edge from the bottom of the boat and mark it on the indicators.

Then you need to determine what is best for your hull, power, drive height, prop, load and indicator.

You didnt really think this power boating thing was that easy did you??

hell no i didnt the boat was 2008 353 fastech with regular 496 ho set up and we were just 4 people no

You will need to experiment with the boat to find out what is the best.
Probably something close to having tabs nearly all the way up and drives up to about the 7 mark.
