Now have a -3" imco sc drive on it and handles like a dream ! Also on one video it go s complete on one side (rub rail hits the water ) due to going of the throttle before trim it back first . The cam specs I don t no have to ask the builder . |
Why the switch from the black hawk?

Another downside is that it goes very fast on idle and also my engine idles at 900 rpm and the blackhawk don t like to get both props moving at that rpm it gives a very loud bang ! So I decided to try a imco which also gives a lot beter prop selection ,I would loved to try a set 31 props on the BH but there very rare and espacialy here in europe . going out today whit a 1" spacer on the imco to look if I can get the hull a little more out of the water and gain some speed . |
I figured that. Looks like your inner lifting strakes go all the way back. Great set up either way
