Hi!

I am now rigging twins on my Phantom 25. I have been reccommended to turn the props outward. I will have twin Merc 2.5 EFI SS engines (15 inch mids) spinning for a start labbed Mirage 27 pitch props. Propheight approx. 1 inch below the bottom.

Would you reccommend to mount the engines toe in or toe out. And how much?

Cheeeers, Toffen G

Well this is the next logical question to the rotation one.
There are to different discussions about this...

1- To go fast with the least resistance and assuming that the water comes off the transom with a slight parting angle than you want to have the toe 'in'.

2- Handling, like the skis on your sled toe in and out effect the stability. So, in opposition to the theory of toe-in is faster, the toe-out is easier to steer in a walk. If your boat does not fly high enough to walk then its not an issue.

But none of this matters because you will try a little "in and out" after you deside on rotation which you also tried both ways.

1/4 inch toe in. Measured at the bullet and tip of prop shaft. At least that's what worked on my twin OBs.

Be safe out there.
