turn fin tuning

[ncornacchi]

I have never folded my UL1 turnfin. Maybe some batches were made using softer aluminum.

With L40 x 57 prop do not be afraid to go deeper on the strut. I went deep using my Nue1515 1y combo. Larger props may need shallower strut setting


...

Yeah, I also run my blue UL1 with a nue1515...I never had luck with the 40x57, would either cavitate or would have to run too deep and wet, could never get past 45mph, slapped a x445 on and she is running 55mph and has alot more to go, not even tuned yet...I did move my rudder up 3/4" the other night and will test her today and also try a M447
