Default Sport20 Whiplash COG

This is probably a dumb question but when I check the COG on my Sport 20 Whiplash I need about 3.5oz's at the back of the boat to balance where they recommend.
Do you ever add weight to the back? I've only added it to the sponson tips on other boats. Maybe my pipe is too light.
Thanks
Brian

Can you add a extended rudder to get the back some weight. Or move your battery to the back. The CoG should be at the turn fin's leading edge or close to it. Also the flywheel coupler area.

Maybe it's fine then where it is. Without any lead it's about in the middle of the turn fin, at the collet. I'll get her wet this week and see.
Thanks!

You should be OK. A riggers CoG is NOT 30 % from the transom.
