Propeller for Zapcat

What type and size of propeller will suit for a Zapcat year 2004 with a new Tohasu 30hp.

The boat is not bought for racing. It will mostly be run with a light load - one adult and one child.

I have two goals and consider using two props.

Goal 1: Max speed without totaly sacrifising the acceleration.
Goal 2: Pulling a tube, kneeboard and maybe even af skier.

The Tohatsu will be delivered with a standard alu prop. Havent seen it yet and dont know what size.

Will a Michigan Ballistic 10 1/8 X 15P fit for goal 1? Its on offer right now.

Any advice will be appreciated.

I think 15" might be a bit big a pitch if you want to pull a skier up with a 30-but I'm no expert on Zapcats.

I'm using a 10.1/8x14" on a 50 mariner on the sr4. Boatster was running a 15" on his 50 Tohatsu.

I was thinking of using different props for the two goals. A highspeed prop and a pulling prop. Maybe the standard alu prop for pulling?

I can get the 15P Ballistic realy cheap. I know from a test on a monohull that the Ballistic is a realy fast prop with lots of grip low slip and best acceleration. Allso it was mentioned that it produced lot of bowlift. Is that good or bad for a Zapcat? I should think a multihull produce enough bowlift by it self.

Allways wondered why not a real cleaver for the Zapcat?

I think the Zapcat 50hp are raced with a 15P semicleaver. But the 50hp. Tohatsu has a bigger hub 3½" to 3" on the 30 hp. Allso the 50hp prop has a slightly bigger diameter. Dont think the two 15P props are direct compareble.

The new youth LC30 class what prop are they using?

them Tunnel hulls like a lot of Cup, bow lift is not really what you want.
choppers make a lot of bow lift, cleavers lift the transom, semi's got some of boath.a semi is the best all a round. i run a cleaver on mine 12 5/8" X 23 or 25p
