You may be using a prop too small in diameter for the boat/setup... Motor rpm is not high enough to use 38mm prop... You should try 42mm prop or 45mm carbon props work well... Lifting props are mostly used on riggers and hydros....

Put either a 42x55 or X442 on it. Sharpened and balanced, both props will pull very well.

I run a 42x55 GrimRacer prop in mine. Works well.

Is that a lifter prop

No, it is a standard prop. I usually do not run lifter props on mono hulls.

just a thought. would the rudder angle cause it to dig in? lower tip of the rudder as fwd as possible, creating a small amount of downward force?

just a thought

Take a look at this site. Tune up tips from the guy who designed the boat

cf 45 is the way to go cheap and it works great.
