        line6,
        not sure what could be wrong? We have two SV27. My brother in-laws was brand new and mine was bought used with about 10 runs. And both were measured with a gps around 27 to 30 with two 6 cell nimh. What is your setup?
        I never ran the stock prop on a gps? What are you measuring your speed with? Have you ran a 220? And if so what speed you getting with that prop?

            with the nimh the batteries were in the stock position. with the lipo's there a bit more forward. Lets say the top of the battery is inline with the motor mount. Not sure what the COG is?

                  Yea that could be. I know with the lipo I'm only getting 37 with the Prather 220. When I get my boat up and running again I'll try the stock prop and see what speed I get.

                    I think the cog should be around 8 1/2 from the transom with lipo's?? Seen that number around here on the forum somewhere.

                      I'll also read 7 1/2 so go figure. I think I'm lossing some speed with all the weight up in the front but she planted for for sure. I'll add some velcro and mess with the cg.

                            Haven't been able to check the temps with the UL-1 setup in my boat yet?
