Props in or out? Current Motion cat runs 130 running number sixes turning the props in. I have the power to run 150 with bigger gears. Not interested in hard turns at 100+ as in offshore racing. In or out at 150 mph?

What size pitch are those props?

in is always faster so if you a straight line shooter keep it that way. both my 31 ao and 32 skater run the fastest that way

I have also found turning in to be faster by a few mph. I am worried about swapping ends at 150. Currently running 17x34 Mercury lab 4 blades. Just wondering what other cats are running for setup.

spinning out give the boat more tail lift so in gives less tail lift. i would spin in and good luck. BE CAREFUL

Hey Charlie, how are you making out with the agitator? Do you have any pix to post. Would like to see and hear about the status

Thanks

Turning in on a v-hull gives less manuverability at slow speeds, marina, parking in slips etc. But better top end and quicker planing. is it the same problem on cats?

Every cat I have owned is a real problem docking compared to a V-hull. They will not slide with those two big "rudders" running the length of the tunnel. Turning in will not handle as well at speed as turning out. But thery do seem to be a little faster top end turning in. It seems to me that boats are running in or out depending on preference? After this post I have looked through some past issue of Powerboat and saw pictures of some very fast cats with props turning in.

they are real bad when they have crashboxes like mine do. just point and shoot.

merlin,

is it ready for some december testing?
