We just purchased a 2015 q series twin 350 that is very heavy on the rear. It has twin gas tanks in the back that we only fill two 70%. Is anybody know where the center of gravity is on that boat? We are trying to determine what to do on our lift. Thank you

Considering the lack of detail in your question. The answer to “what to do on our lift” is park it forward.

General consensus is the cockpit is about the COG of most of our boats. With twins, it might be even farther back.

You can get a close estimate of CG location if you assume the CG of a boat without a motor is in the middle. If the weight of heavy motor(s) and associated items is known one can estimate how far back the CG moves from midpoint.

Why only fill tanks 70% ? Fill them up and do a test run on your lift. You can't go left to right so go forward as much as you can and then start moving her back until your comfortable. Your lift will support the boat right?

Agreed.
So long as your lift is rated for the boat weight (+ people and gear), I’d play around with how it sits on the lift to find the right spot. Might be hard to pinpoint an answer to your question from fellow forum members here - not as much concrete collective ownership with that particular boat.
As others have said the general consensus on a normal tritoon is approximately the helm area as the center of gravity (+/- 1/3 of the way from aft towards front). Yours, well maybe less with all that rear weight (That’d be my guess). Start there (helm area) with your lift and play with it as Illinois mentioned above.
