Propeller rotation
 

Any ideas about prop rotation?The boat is a Scarab 38KV with notched transom and high X-dimension (TRS).

I have been forced to spin my Mirage props inward because of incredible poor hole shot (blow out problems).But I'm going for Bravo 1. 4 blade this year and think that problem is gone.

Most twin eng boats i have seen are spinning their props out. What can I expect in overall boat behaving by swaping the drives?

Bow/stern lift, less or more slip, top end, etc.etc.

Thanks in advance.

Switching from spinning out to in I experienced bow lift and a loosening up of the hull. Gained speed too. 30' Scarab Panther, bravo drives. About 1/8 of hook at the transom.

Going to the four blades should
solve your blowing out when
coming out of the hole.

Outside rotation on vee's gives
stern lift.

I've found on various boats that I've
changed rotoation on: that the handling
seems more "shure" turning out.

Docking maneuverability
is much better when turning out.

The top speed differences have only been
around 1 mph, in favor of inside rotation.

yes,Bravo -one props are nice but we can work your three blade props to almost no blow-out on take -off and possibly increased speed as well,give me call and I will try to help.
