Worked ok for boarding and skiing slow to get out of the hole
We run 1600lbs for surfing and that definitely made it struggle.

Much stronger out of the hole for boarding and skiing plus better top speed
surfing with 1600 lbs much better out of the hole and doesn't seem to bog the engine down as much. Seems to be much easier to hold speed while surfing. 2100 RPM @ 10MPH
