Twin Modified motors( 2.5's and 300x) have pushed 28 Skaters over 125.
My question is where do the new XS motors stand in this comparison?

I am going with 1.62 gear ratio, 14 1/2 x 32 cleaver 3 blades. When Jim was at at the Powerboat Mag test for the 30 skater, they ran 32s, but Jim & I are hoping we run out of prop and plan to try a 34.

My boat is runing 109 full of fuel or empty with 15x34 cleavers stock. I saw 112 on a flat calm day.
your boat easily will turn the 34's
The boat ran 118 with the 280's 116 everyday so I know more speed is in it.

Dan So as of now the 300xs lost app.5mph compared to the 280ros ? Did the boat gain weight as a result of the pleasure conversation?

I have not weighed the boat. I don't think it is slower because I am on the rev limiters with the 34's. The motors stop making horsepower at 6100-6150 cylinders are flooded oil. The efficiency of the boat carry the boat to 6300 and the motors go into gaurdian mode.
If I had a set of 36 pitch props the boat would be faster.
Basically its going to be difficult with the 07 model year motors to see 120 mph with out custom props. I would bet that eventually mercury will increase the rpms on the motors as they get more time.
