Is that Kilometers perhaps

The GPS does not BS maybe you do!

sweet boat,what was the rpm when she was driveing?

She only had it to 5700 RPM that was enough for her she said.

there is no doubt thats a better boat then what I'm runnin but the numbers don't add up. We run a 33 elimianator with 632 tall decks NA with dry sump 6 drives 132 gears and 16/3/4 x 35 merc lab four blades the mills dyno at 944 hp.
when we let it eat she spins 6 to 62 at 135.

One Question.... How come in the picture of your girlfriend driving the boat you do not see the back side top of the GPS / Speedo???? Based on the other picture of the GPS / Speedo you should clearly be able see the top of the back of the Speedo gage as it appears to be above the dash... For some strange reason its not there.... Things that make you go Hummmmmmm........

what kinda boat is that ?
